Designing the parts of an application where orings will be applied is broadly termed "oring groove design" In order to seal properly, the oring has to deform in the application by being compressed and stretched in any number of ways The design of the groove where the oring sits plays a major role in how the oring performs its sealing role Extrusion Limits;Sure act on the Oring in the same direction Groove design can reduce the tendency for extrusion See figures 132 a & b If the friction of the moving metal surface across the Oring is in the same direction as the direction of the pressure, the Oring will be dragged into the clearance gap more readily and thus extrude at about 35% of theORing Face Seal Glands These dimensions are intended primarily for face type Oring seals and low temperature applications ORing Size Parker No 2 W Cross Section Nominal Actual L Gland Depth Squeeze Actual % G Groove Width R Groove Liquids Radius Vacuum and Gases 004 through 050 1/ ±003 (178 mm)050 to to023 19 to to to0005 to015
