What Is An O-Ring?
O-Ring DescriptionAn O-Ring is a torus, or doughnut-shaped object, generally made from an elastomer.O-Rings can also be made in PTFE and other plastic materials, and in metals, both hol-low and solid. They are used primarily for sealing. Another use is for light duty drivebelts.
Basic PrinciplesAn O-Ring seal is a means for closing off a passageway preventing an unwanted escapeor loss of fluid. The seal consists of an O-Ring installed in a gland and is exactly that -a circular run in which the elastomeric material has a section that is virtually circle.The gland is the cavity (usually within metal) into which the O-Ring is placed. Thecombination of these two elements comprises an O-Ring seal.
UseO-Rings are used in two general design applications: static (non-mov-ing) and dynamic (moving). Static applications may range from vacu-um to over 60,000 psi for sealing flanges and O-Ring grooves. O-Ringseals with lobed cross sections were designed for both static anddynamic applications. The four and six lobed configurations resist spiralfailure and also extrusion failure in applications with large clearancebetween parts. Of the some 20 different types of O-Ring seals available, the commonround cross section O-Ring type is the most versatile. The conventional type of O-Ringmay be used in almost any application if the gland to contain the seal is deisgned cor-rectly and the right size and material is chosen.
OperationAll fluid-tight seals are characterized by the absence of any passage by which fluidmight escape. Detail differences exist in the manner by which zero clearance isobtained - welding, brazing, soldering, ground or lapped fits or the yielding of a softermaterial wholly or partially confined between two harder and stiffer members of thestructure. The O-Ring seal falls in the latter class. The rubber seal should be consid-ered as an incompressible, viscous fluid having a very high surface tension. Now,whether by mechanical perssure from the surrounding structure or whether by pressuretransmitted through hydraulic fluid, this extremely viscous fluid (the elastomeric O-Ring) is forced to flow in the gland to produce zero clearance or a positive block to theflow of the less viscous fluid being sealed. The rubber absorbs the stack-up of toler-ances of the unit and its memory maintains a sealed condition.
Before Installation After Installation With System Pressure
How To Achieve Optimum Performance of An O-Ring
The successful use of O-Rings depends upon many factors:
A. Surface Finish - All metal surfaces over which the O-Ring moves shouldbe held to a maximum finish of 16 RMS, although the groove finish canhave a maximum of 32 RMS. There should be no nicks, burrs, orscratches.
B. Metals - All metals over which anO-Ring moves should have a hardsurface such as steel, nickel-plated,or chrome-plated. Special attentionshould be given if you select softmetals such as aluminum, brass, orbronze.
C. Excessive Metal Clearance -Clearances should be held to therecommended maximum diametricaltolerance. Consideration must be given to the breathing of cylinder in yourcalculations - which is the possibility of the cylinder bore to expand orballoon out at its center.
D. Concentricity - It is important to hold eccentricity within therecommened practice and to design for sufficient bearing area to takecare of side loads or off center loading.
E. Cleanliness - All systems should be kept clean and free from dirt, grit,chips, and any foreign materials. Any type of abrasive material will cut theO-Ring. When replacing a failed O-Ring, look for tiny metal chipsembedded into the O-Ring, which could mean a pump problem.
F. Squeeze (preload) - For good sealing, the minimum diametrical squeezeshould be observed. Where pressures are low and friction is critical, theamount of squeeze can be decreased but caution should be excercized.
G. Lubrication - When used in pneumatic systems, O-Rings should be lubri-cated. If permitted to run dry, then they will face abrasion and twisting.
H. Groove Design - Proper design is a most essential factor in the successfuloperation of O-Rings. The rectangular shaped groove is recommendedexcept for special applications.

O-Ring Characteristics
An early and prominent user of O-Rings cites characteristics of O-Ring seals of interestto designers. 1The more general characteristics are:
A. The seals can be made perfectly leak-proof for cases of static pistons andcylinders for fluid pressures up to 5,000 psi (limit of test pressure). Thepressure may be constant or variable.
B. The seals can be made to seal satisfactorily between reciprocating pistonsand cylinders at any fluid pressure up to 5,000 psi. There may be slightrunning leakage (a few drops per hundred strokes) depending on the filmforming ability of the hydraulic medium. O-Rings can be used betweenrotating members with similar results but in all cases the surface rubbingspeed must be kept low.
C. A single O-Ring will seal with pressureapplied alternately on one side and then onthe other side. However, in cases of severeloading or usage under necessarilyunfavorable conditions, seal life can beextended by designing the mechanismso that each seal is subjected to pressurein one direction only. Seals may be arrangedin series as a safety measure, but the firstseal exposed to pressure will take full load.
D. O-Ring seals must be radially compressed between the bottom of the sealgroove and the cylinder wall for proper sealing action. This compressionmay cause the seal to roll slightly in its groove under certain conditions ofpiston motion, but the rolling action is not necessary for normal operationof the seals.
E. In either static or moving applications, when the O-Ring seal is under highpressure the primary cause of seal failure is extrusion of the seal materialinto the piston-cylinder clearance. The major factors affecting extrusion arefluid pressure, seal hardness and strength, and piston-cylinder clearance.
F. Moving seals may fail by abrasion against the cylinder or piston walls. Therefore, the contacting surfaces should be suitably finished for long seallife. Moving seals that pass over ports or surface irregularities, while underhydraulic pressure, are very quickly cut or worn to failure.

O-Ring Limitations
Although it has been stated that O-Rings offer a reasonable approach to the idealhydraulic seal, they should not be considered the immediate solution to all sealingproblems. It has been brought out in the forgoing discussion that there are cetain defi-nite limitations on their use, for example, high temperature, high rubbing speeds, cylin-der ports over which seals must pass, and large clearances. Disregard for these limita-tions will result in poor seal performance. Piston rings, lip type seals, lapped fits, flatgaskets and pipe fitting all have their special places in hydraulic design, but where thedesign specifications permit the proper use of O-Rings, they will be found to give longand dependable service.2
While no claim is made that an O-Ring will serve best in all conditions, it merits consid-eration for most seal applications except:
A. Rotary speeds exceeding 1,500 feet per minuteB. An environment completely incompatible with any elastomeric material.C. Just plain insufficient structure (for anything but a flat gasket).

O-Ring Without Pressure
O-Ring With Pressure
Why Do O-Rings Fail?
O-Rings, made of an elastomeric material, are unlike other materials. The reason forthis is because in order for an O-Ring to function properly it is has to deform. Once anO-Ring is installed into a gland it is then compressed resulting in zero clearance. It’sthat zero clearance that seals the flow of fluids and gases. As the actuating pressureincreases, so does the force acting on the surfaces, making a tighter seal and deform-ing the O-Ring. This sealing procedure works well for a lot of fluid-power systems.However, in order for it to work well it requires careful design, selection, and installa-tion procedures.
The combined effects of different environmental factors usually result in a typicalO-Ring failure. Some of the most common causes of an O-Ring failure are:
A. Incompatibility between the O-Ring material and the fluid it is to seal.(See our Fluid Compatibilty Guide on pages 44-103)
B. The wrong O-Ring size.C. O-Ring not installed correctly.D. Improper gland design. This allows for too much compression and too little
compression, not enough room for displacement under compression, ortolerance stack-up.
E. Not enough O-Ring lubrication.

O-Ring Failure Analysis
COMPRESSION SET
Description of failure appearance:This failure is common to both static and dynamic sealing applications. This type offailure produces flat surfaces on the sides of the O-Ring that were compressed, usuallythe top and bottom if sitting flat on a desk.
The sources of COMPRESSION SET failure:• The O-Ring material used has poor compression set resistance• The O-Ring material used has limited resistance to heat• The O-Ring is swelling in the groove due to fluid incompatability• The O-Ring has too much squeeze in the groove
How to eliminate COMPRESSION SET failure:• Use a higher quality, low compression set material• Check the compatability of the O-Ring material to the fluid• Select a material good for heat produced in operation• Double check the groove dimensions for proper squeeze• Check existing O-Ring stock for physical properties

“The Top Four Causes of Hydraulic Cylinder Seal Failure”by Jerry Whitlock - The Seal Man™
Hydraulic cylinder seals cost the manufacturer pennies. They are usually purchased ona low bid basis. But, that simple, inexpensive seal can cost you thousands in downtimeand loss of production if it fails. If you have a problem seal, focus on these four pointsto help determine the cause of failure.
1. Improper installation is a major cause of sealfailure. The important things to be watched duringseal installation are: (a) cleanliness, (b) protectingthe seal from nicks and cuts, and (c) proper lubri-cation. Other problem areas are over tightening ofthe seal gland where there is an adjustable glandfollower or folding over a seal lip during installa-tion. Installing the seal upside down is a commonoccurrence, too. The solution to these problems iscommon sense and taking reasonable care during assembly.
2. System contamination is another major fac-tor in hydraulic seal failure. It is usually caused byexternal elements such as dirt, grit, mud, dusteven ice and internal contamination from circulat-ing metal chips, break-down products of fluid,hoses or other degradable system components. Ascontamination can be prevented by a proper filter-ing of system fluid. Contamination is indicated byscored road and cylinder bore surfaces, excessiveseal wear and leakage - and sometimes tiny pieces of metal imbedded in the seal.
3. Chemical breakdown of the seal material is most often the result of incorrectmaterial selection in the first place or a change ofhydraulic system fluid. Misapplication or use ofnon-compatible materials can lead to chemicalattack on the seal by fluid additives, hydrolysisanoxidation reduction of seal elements. Chemicalbreakdown can result in loss of seal lip interface,softening of seal durometer, excessive swelling orshrinkage. Discoloration of the seal can also be anindicator of chemical attack.

“The Top Four Causes of Hydraulic Cylinder Seal Failure”by Jerry Whitlock - The Seal Man™
(continued)
4. Heat degradation is to be suspected when thefailed seal exhibits a hard, brittle appearanceand/or shows a breaking away of parts of the seallip or body. Heat degradation results in loss ofsealing lip effectiveness through, excessive com-pression set and/or loss of seal material. Causesof their condition may be use of incorrect sealmaterial, high dynamic friction, excessive lip load-ing, no heel clearance and proximity to outsideheat source. Correction of heat degradation problems may involve reducing seal lipinterference, increasing lubrication, or a change of the seal material. In borderline sit-uations consider all upper temperature limits to be increased by 50 degrees Fahrenheitin hydraulic cylinder seals at the seal interface due to running friction caused by thesliding action of the lips.
Here’s a secret - it is not necessary tobuy replacement seals from the originalhydraulic cylinder manufacturer. Manyseal suppliers have the same exactseals that are used in most hydrauliccylinders and can easily cross referenceor match up a replacement. In manycases, if there is a recurring problemwith a seal, our seal specialist can rec-ommend a solution and increase the lifeof the seal.
Jerry Whitlock in known as The Seal Man™. He has over 30 years experience in theseal industry. Jerry owns and operates EPM, Inc. located in Atlanta, GA. His web site -www.epm.com - is the largest and most visited web site for seals on the internet.

*The Shore A scale is used to measure the hardness of elastomers, rubber-likematerials, and plastomer materials like polyurethane.
This chart shows the overlapping scales for measuring the hardness of non-metallic materials.
The unit of measurefor all of these scalesis called durometer.
Example:A standard NBRO-Ring is 70durometer Shore A.
The higher the number the harder the material.

Armor-O-Rings™ / PTFE-FEP Encapsulated O-Rings
Armor-O-Rings™ are produced using a thin PTFEshielded tubing fully encasing an elastomeric rubber-like core. The outer jacket protects the resilient corefrom the fluids which the O-Ring contacts. This uniquecombination enables the Armor-O-Ring to give maxi-mum protection in even the harshest environment.PTFE is an ideal sealing material, however, it is notresilient by itself. The elastomeric core material,either silicone or Viton®, gives the outer PTFE shield
the memory required to effect a proper seal. It will provide anexcellent seal in high temperatures, aggressive chemical expo-sure and still remain elastic.
The Armor-O-Ring™ style EOV and EOS have a PTFE-FEP jack-et with a minimum thickness of .008”. This casing is far supe-rior to a simple coating of PTFE. Illustration (A) below showthe typical wall thickness relative to the cross section of the
O-Ring. The PTFE shield is virtually chemically inert and resists most chemicals, exceptmolten metals, fluorine at higher temperatures, and certain complex halogenatedcompounds.
Type Armor-O-Ring™ EOVConstruction: Core made using Viton® fluorolastomer corewith PTFE-FEP encapsulation.
Uses: Chemically resistant to most fluids and gases, exceptmolten alkali metals, fluorine at elevated temperatures andsome complex halogens. Especially suited for oils and solvents.
Temperature: -40° to 205°C / -40° to 401°F
Type Armor O-Ring™ EOSConstruction: Core made using silicone rubber core withPTFE-FEP encapsulation.
Uses: Excellent for cryogenic applications, broad chemicalapplication and most any application requiring a resilient,chemical resistant seal.
Temperature: -73° to 205°C / -99° to 401°F

AN6227 is an Air Force-Navy Auronautical Standard that covers 88 sizes of AS568.MS28775 is the basic standard on which AS568 was developed. M25988, M83248,MS9020, MS9355, and MS29512 cover 31 O-Rings of slightly larger diameter crosssections to be used for sealing straight-thread tube fittings. These O-Rings are usu-ally referred to as “3 dash 9” O-rings and are equivalent to dash numbers 901through 932 of AS568. They are used in gland designs specified by military stan-dards MS16142, MS33649, and MS33656 for tube fittings.
Special sizes and custom made O-Rings are available in any material.Contact your EPM Customer Helper for details.

O-Ring Storage, Handling, and Installation
To achieve the expected lifespan of an O-Ring, proper storage, proper handling and carefulinstallation or O-Rings is necessary to avoid damage to the material and surface, both prior toand during installation - which would adversely affect service life.
The best practical way to store O-Rings is inside a sealed polyurethane bag and then placed ina closed box or container which light cannot penetrate. Options include individually packagingO-Rings in polyethylene-lined craft paper bags - heat sealed to close.
A. Proper Temperature and Humidity Levels: O-Rings should be kept cool(below 30°C / 86°F) with an average relative humidity of 40% to 70%. Excessive humidity will deteriorate some seal element material as well ascause corrosive damage to metal cases and spring.
B. Shield from direct sunlight and ozone: To slow ozone aging, O-Ringshould be kept away from direct or reflected sunlight and electrical equipmentthat may generate ozone. Excessive heat build-up in the storage area and/orexposure to ozone can cause premature deterioration of the O-Ring, thisreducing expected life.
C. To avoid mechanical damage: O-Rings should be stored in aplace other than a work area to avoid possible mechanical damage byequipment or falling objects. A sealed, closed container should provideprotection from mechanical damage, as well as from dirt, dust, grit and othercontaminants. When boxes of O-Rings are stacked, take care to avoiddamage and crushing to the bottom box of parts due to excessive weightresting on the container.
D. Avoid radioactive materials: O-Rings should be protected from radioactivematerials and certain fumes which can also cause deterioration of sealelement.
E. First in / first out: O-Rings should be stored and selected on a “first in, firstout” basis, since, even under ideal conditions, an unusually long shelf-life maycause deterioration of element materials.
F. Rodents and insects: O-Rings should be protected from rodents and insects,some of which thrive on molded rubber products.
G. Packaging for shipping: The O-Rings should be protected from damage andforeign material during shipping from the manufacturer and during finalstorage. They should not be removed from their packaging until ready forinstallation; this will ensure protection and clear identification. Duringunpacking, take care so as not to cut or tear the seal element with sharpinstruments, such as knives, screwdrivers, etc.
Special note: Some O-Ring compounds can aggressively attack clear polycarbonate plastic known as Plexiglas. For best results, avoid storing or shipping O-Rings in containers made from this material.
