OEM customized round flat heat resistant rubber washer

This round flat rubber washer provides a shaped layer around a central opening within a custom assembly. The inside diameter, outside diameter, and thickness should be selected together to suit the mating parts. Its flat cross section needs support across the intended contact area.

For a warm location, choose the compound for the actual temperature and exposure duration. The washer's compression also depends on the fastening arrangement and the space available as the joint closes. Material suitability and dimensional fit need to be established separately rather than assuming that a heat-resistant description resolves both.

Check that the central hole clears the intended fastener or shaft without leaving an excessively narrow supported ring. Install the washer flat on clean surfaces and avoid trapping an edge as the parts are tightened. If the washer serves a sealing role, evaluate the complete joint with the actual medium and operating conditions. During service, inspect for cuts or permanent flattening and replace the washer with the correct thickness so the assembled stack remains as intended.
