o-ringsThe O-ring is the most widely used seal in industry today. It is simple in concept, easy to install, can be used as a double-acting seal,can seal pressures to over 5,000psi in static and dynamic applications and, best of all, is very economical.

While simple in concept, it can be very sophisticated in its applications. This catalogue is intended to give just a brief overview ofO-ring design and selection. When information beyond the scope of this catalogue is required, please visit our website or contact aDaemar technical service representative.

H w t pec o-

O-rings are specified by calling out (1) the O-ring size (inside diameter and cross section), (2) the compound and (3) the hardness.

i e t the c ect ze:O-rings are available in 349 standard inch sizes as set up by the Aerospace Standard 568 published by the society of AutomotiveEngineers. These sizes are designated by dash numbers as shown in the sizing tables on pages 23 to 31. For O-ring sizes other than these standard AS sizes, specify the actual dimensions desired for the inside diameter (I.D.) and the cross section (W).Measurements can be made with calipers or with one of several o-ring measurement tools (sizing chart, measurement cone). Ourstandard metric o-ring sizes are listed on pages 33 to 37 and standard Boss sizes on page 32.

se ect c p :

i) Check compatibility with the fluid media to be sealed (see tables pages 13 to 20)

ii) Identify the operating temperature range required (see material specifications on pages 6 to 8)

iii) Identify other general properties that are required for the application, check these properties against the performance of variouscompounds in the comparison of properties table on page 4.

dete H e :

Now that a base compound has been selected the next step is to determine the durometer (hardness) that is needed for theapplication. The Durometer chart (page 5) identifies the correct level of hardness for the corresponding fluid pressure and maximumextrusion gap.

The chart matches the general rubber properties required in most O-ring applications with the capabilities of commonly usedelastomers. Since no one elastomer is rated excellent for all properties, compromises are sometimes necessary when selecting anelastomer for a specific O-ring application. Start with the most critical properties to narrow your choices.

TEmPEraTurE rangE CHarTThe temperature range for any compound is determined by the base elastomer used. This chart depicts the maximum temperature range for each elastomer. The temperature rangefor a specific compound may not reach these maximum limits.Higher temperatures may be considered if exposure is short term or intermittent.

The hardness of rubber compounds is commonly measuredby the Shore 'A' durometer; the higher the durometer number, the harder the compound. 70-durometer hardness should beused wherever possible as it offers the best combination ofproperties for most O-Ring applications. Softer compoundsstretch easier and seal better on rough surfaces. Hardercompounds offer greater abrasion resistance and resistance to extrusion. Extrusion must always be considered where highpressures are used. The proper hardness may be selected from this chart by matching the fluid pressure with the maximumextrusion gap.

CHEmiCal rEsisTanCEBecause Kalrez has outstanding chemical resistance,it withstands nearly all classes of chemicals. With thiscombination of high thermal stability and excellent chemicalresistance, the Kalrez perfluoroelastomer parts rating may beconservative, as actual field experience and the example abovehave demonstrated.

In comparing the chemical and fluid resistance of Kalrezperfluoroelastomers to that of Teflon fluoropolymer resins,certain differences should be kept in mind:

Kalrez is an amorphous low-modulus rubber whereasTeflon is a crystalline high-modulus plastic. In fluidenvironments where high permeation occurs, Kalrez willprobably swell to a greater extent than Teflon, even though the polymer is not chemically attacked. Environments in

which this is most noticeable are fully halogenated solvents,Freon, and Freon alternatives. Service ability of Kalrezin these environments will be dependent upon the specificsof the application.

As with all elastomers, it is necessary to compoundKalrez perfluoroelastomers with fillers and curatives togain desired mechanical properties for functionality. In alimited number of environments, even though the polymeris stable, the fillers and curative systems may interact with the chemicals. However, because the level of fillers inKalrez perfluoroelastomers is much lower than in mostother elastomers, such filler interactions are generallynegligible with Kalrez parts. Where such interactionscan occur, such as in highly oxidative environments,service performance is dependent on the conditions of the application and may be affected by compound choice.

Because each application is unique, it is recommended thatusers of Kalrez perfluoroelastomer parts always conduct their own evaluations to determine the suitability of Kalrezfor their application. Because of laboratory constraints anddifferences in field applications, the results shown in this technical information may be based on conditions that maynot necessarily reflect actual operating environments for aspecific application. Additionally, many elastomeric materialsmay show excellent chemical resistance to pure reagentsin relatively short-term laboratory tests. However, they mayfail in actual service because of chemical attack by additives

and/or impurities. Kalrez perfluoro-elastomer parts, with their near-universal chemical resistance, provide an extradegree of safety against these unknown corrosive influences.Case histories are available from Daemar detailing provenperformance of Kalrez parts in over 100 specific chemicalapplications. Information on test performance in a limitednumber of specific chemicals is also available through yourauthorized Kalrez distributor.

CauTionKalrez perfluoroelastomer parts, like all fluorinated products,should not be exposed to molten or gaseous alkali metals, suchas sodium and potassium, because a highly exothermic reactionmay occur. At elevated temperatures above 100C (212F),service life may be significantly reduced in fluids containing highconcentrations of some diamines, nitric acid, and basic phenols.Kalrez parts should always be tested for suitability.

Note 1. The following sizes are not normally recommended for dynamic service, although special applications may permit their use:

-001 thru 003 -013 thru 050 -117 thru 178 -223 thru 284 -350 thru 395 -461 thru 475

Note 2. Clearances shown are based on 70 durometer materials. The clearances must be held to an absolute minimum consistent with designrequirements for temperature variations and should not exceed the values shown.

Note 3. Total indicator reading between groove and adjacent bearing surface. All surfaces and corners must be free of tool marks and scratches.

In all dynamic applications, proper lubrication and good heat dissipation are essential to long seal life and performance. In pneumaticapplications, supplemental lubrication should be provided. Lubricants should be selected on the basis of the material of which the O-Ring is made and the type of service to which it will be subjected. (See Table). In other instances the lubricant can be molded into theO-Ring, or Teflon or other coatings can be applied to the surface.

dynamiCsEalingThe O-Ring moves relative to the mating surface. Amoving seal may be furtherclassified by the type ofmotion: reciprocating,oscillating, or rotating.The greatest number ofdynamic seals are usedin reciprocating servicein cylinders, valves, andlinear actuators. Oscillatingmotion is encountered inswivels and valve stems.When an O-Ring is used ona rotating shaft, it should belimited to light duty where the shaft speed is lowand some fluid bypass isacceptable.

o-ring sTrETCHAs a general rule of thumb the groove I.D. shouldstretch the O-Ring I.D. bybetween 1 to 3% and by no

more than 5%. Exceeding this limit may over stress the material (see Gow-Joule Effect on page 36).

THE goW-JoulEEFFECTThis effect can occur whenelastomers are subjected to heat or friction. It ischaracterized by the tendancy of elastomersunder tension to shrinkwhen heated rather than expand as is mostcommonly believed. Thiseffect sets up a destructivesituation where as heat andfriction build up the O-Ringshrinks thus causing moreheat and friction.

The Gow-Joule Effect canbe avoided by installing the O-Ring in compressionrather than tension.

sEalingPrEssurECreated by compressionof the seal between themating surfaces of thegland and external forcessuch as the pressureexerted by the fluid beingsealed. Low-pressureapplications (below 100psi), rely on the O-Ringsability to deform (materialhardness) and the surfacefinish of the seal and thegland. In high-pressureenvironments, systempressure compresses theseal and thus factors suchas seal material hardness,cross sectional width andgap clearance are moreimportant than seal andgland surface finishes.

longEr sEal liFEBecause less squeeze means less friction with the four-lobedesign, seals last longer. This means equipment in which theQuad-Ring seal is installed will operate longer and require lessmaintenance.

no ParTing linE on sEalingsurFaCEUnlike O-Rings, where partitioning lines are on the sealingsurface, Quad-Rings seals parting lines lie between the lobes,away from the sealing surface. This design eliminates theproblems of leakage resulting from a parting lines irregularsurface.

aVoiding sPiral TWisTTo minimize breakaway friction, an O-Ring groove must be wideenough to allow rolling or twisting of the seal. In the long strokeof a reciprocating seal application, this twisting action canstrain and eventually tear the rubber, causing a failure modeknown as spiral twist.

To prevent spiral twist, the Quad-Ring seals four-lobedconfiguration is designed to withstand the distortion andextrusion often caused by high or pulsating pressure. Toaccommodate these forces, a Quad-Ring seal uses a narrowergroove than a comparable O-Ring seal.

Using the table above, determine the maximum recommendedgland depth for your application. Then, calculate the Quad-Ringgroove diameter as follows:

. Fo o ( h t) e :

Quad-Ring Groove Diameter = Min Shaft Diameter+ (2 X Recommended Gland Depth)

b. Fo bo e (p to ) e : Quad-Ring Groove Diameter = Max Bore Diameter (2 X Recommended Gland Depth)

c. Fo ce e : Quad-Ring Groove Depth = Recommended Gland Depth Application Clearance

With a face seal, if the two surfaces to be sealed are in directcontact (such as with a cover), the seal groove depth is simply the Recommended Gland Depth.
