Customized high temperature oil resistant FKM rubber o ring

A viton rubber o ring should be selected around the specific oil and temperature at its sealing location. Oil exposure can include additives or cleaning residues as well as the primary fluid, making the actual service mixture relevant to compound choice. The ring's dimensions then need to suit the groove and the changing gap through the operating cycle.

Check the section support in the direction of pressure and identify whether the joint remains static or moves. A high temperature requirement should be evaluated at the seal itself, including startup and cooldown, rather than inferred from a nearby machine temperature or a general material name.

Install the ring without twist and use only compatible assembly aids where needed. Keep sharp shoulders from contacting the section as it enters the groove. During service, inspect for swelling, hardening, cuts, or material pushed into a gap. If the oil specification changes, reassess the chosen compound before continuing with the same replacement solely because it fits the existing groove dimensions.
