Dimensions of rings for dynamic and static applications. Approximately 200 sizes ‘O’ seals 0.070 in to 15.475 in internal diameter, and 0.070, 0.103, 0.139, 0.210 and 0.275 in cross-section. Recess dimensions, tolerances for ‘diametral sealing’ of reciprocating mechanisms, and ‘face sealing’ for flange and chamfer type seatings in static applications, working pressures to 1500 lbf/in2. Values of maximum roughness for the surface of metal parts in contact with the ‘O’ seal, for static and moving part s.
