O-RING- Elastomers and other materials -Edition March 2005Busak Shamban5

O-RingDescriptionAdvantagesO-Rings offer the designer an efficient and economicalsealing element for a wide range of static or dynamicapplications.Inexpensive production methods and its ease of use havemade the O-Ring the most widely used seal.A wide choice of elastomer materials for both standardand special applications allow the O-Ring to be used toseal practically all liquid and gaseous media.O-Rings are vulcanised in moulds and are characterisedby their circular form with annular cross section. Thedimensions of the O-Ring are defined by the insidediameter d1 and the cross section d2.Cross section diameters of approx. 0.35 to 40 mm andinside diameters up to 5,000 mm and more areavailable.Compared with other sealing elements, the O-Ring hasa wide range of advantages:- Inexpensive, allows low cost solutions- Simple, one piece groove design reduces hardwareand design costs- Compact design allows smaller hardware- Easy, foolproof installation reduces risk- Applicable to a wide range of sealing problems, static,dynamic, single or double acting- Wide compound choice for compatibility with mostfluids- Ex stock availability worldwide for easy maintenanceand repair.Standard size range for O–RingsStandard/DimensionrangePreferred metric dimensions1.0 1.5 2.0 2.5 3.03.5 4.0 4.5 5.0 5.56.0 7.0 8.0 10.0 12.0International standardISO 3601/1German standardDIN 3771/11.803.55Swedish standard SMS 15861.6 2.4 3.0 5.7 8.4French standard1.9 2.7 3.6 5.33 6.99Japanese standard JIS B 24011.9 2.4 3.1 3.5 5.7 8.4American standard AS 568 ABritish standard BS 18061.783.53American standardAS 568 A (Series 900)1.02 1.42 1.63 1.83 1.982.08 2.20 2.46 2.95 3.00Special versions for largediameters fromapprox. 1,000 mm to 5,000 mm5.0 5.4 7.0 7.79.2 10.0 12.0Ø d2Ø d1Figure 1O-Ring dimensioningO-Ring cross sectiond2 (mm)2.655.30 7.02.625.33 7.0Edition March 20056

O-RingMethod of operationO-Rings are double-acting sealing elements. The initialsqueeze acting in a radial or axial direction due to theinstallation gives the O-Ring its initial sealing capability.These forces are superimposed by the system pressure tocreate the total sealing force which increases withincreasing system pressure.Under pressure, the O-Ring behaves in a similar way toa fluid with high surface tension. The pressure istransmitted uniformly to all directions.ApplicationsO-Rings are used as sealing elements, as energisingelements for hydraulic slipper seals and wipers and thuscover a large number of fields of application. There areno fields of industry where the O-Ring is not used. Froman individual seal for repairs or maintenance to a qualityassured application in aerospace, automotive or generalengineering.The O-Ring is used predominantly for static sealingapplications:- As a radial static seal, e.g. for bushings, covers, pipes,cylinders- As an axial static seal, e.g. for flanges, plates, caps.- O-Rings in dynamic applications are recommendedonly for moderate service conditions. They are limitedby the speed and the pressure against which they areto seal:- For low duty sealing of reciprocating pistons, rods,plungers, etc.- For sealing of slowly pivoting, rotating or spiralmovements on shafts, spindles, rotary transmissionleadthroughs, etc.pFigure 2O-Ring sealing forces with and withoutsystem pressureEdition March 20057
