FKM, NBR, EPDM and Silicone O-Rings — Service Life and Replacement Criteria

These circular-section O-rings are offered in NBR, HNBR, FKM, EPDM and silicone compound options for drawing-defined sealing applications. Specify inner diameter, cross-section, tolerances and hardness together with the mating gland. Material options are selected separately; matching dimensions do not make different compounds interchangeable.
 
Service life depends on compound, fluid exposure, temperature, squeeze, motion and pressure cycles. For hydraulic, pneumatic, plumbing or machinery applications, include cleaning fluids and shutdown conditions as well as normal operation. Define inspection criteria for cuts, swelling, hardening or permanent deformation; durability and replacement intervals require application-specific evaluation.
