High temperature resistant FKM rubber round washers for seal

FKM rubber round washers provide custom annular sealing components for defined joints. The inner diameter, outer diameter, and thickness should place the rubber over the intended sealing land while clearing the central feature. FKM is the named compound family for this version, and the selected formulation needs to suit the actual application.

Consider the contact medium and local temperature together. A broad material name does not establish compatibility with every substance at every condition. The joint must also provide controlled compression and support the washer so it is not pushed into an adjoining gap. Check the complete secured assembly when assessing fit.

During installation, keep the washer flat and centered. Avoid stretching it over a sharp feature that can nick the inner edge. Clean mating surfaces are important to continuous contact. If the old washer shows damage concentrated in one region, inspect that part of the seat before replacing it. The new component should match the specified geometry and material configuration rather than only the visible diameter.
