Factory custom EPDM rubber gasket silicone washers

An EPDM rubber gasket should be identified by its compound and geometry when used in a custom washer arrangement. Silicone is another material option associated with this product. The choice needs to follow the actual contact medium, temperature, and cleaning exposure, even where two variants share the same visible shape.

Define the inside opening, outside boundary, and section thickness from the mating assembly. These dimensions establish the supported contact area and the space available as the joint closes. A material change should be considered with the required hardness and installed behavior rather than treated as a cosmetic substitution.

Fit the selected gasket cleanly and confirm that it stays centered during closure. Keep similar variants separated during servicing so that a matching outline is not mistaken for a complete material match. Inspect removed components for swelling, cuts, or lasting deformation. Replace them with the specified formulation and profile, preserving the joint's intended contact conditions rather than choosing whichever washer is nearest in size.

Material options

EPDM / Silicone. Custom formulation and color for the intended contact conditions.

Hardness selection

Rubber: 30–90 Shore A. Silicone: 20–80 Shore A. Compare the silicone or rubber grade with inside opening, boundary and thickness fixed, evaluating deformation in the mating assembly.

Custom dimensions

Define the inside opening, outside boundary, and section thickness from the mating assembly.

Fit & assembly

Fit the selected gasket cleanly and confirm that it stays centered during closure.

Use & inspection

Inspect removed components for swelling, cuts, or lasting deformation.
