EPDM rubber seal ring custom made silicone rubber gaskets

An EPDM rubber seal ring should be chosen for the medium and temperature of its intended joint, while a silicone gasket version needs its own material and geometry selection. A ring and a flat gasket can occupy similar overall areas but create different contact sections. The surrounding groove or mating face determines which format belongs in the assembly.

Check the section dimensions, supported sealing width, and closing gap. Include any movement or pressure direction that changes how the rubber is loaded. Keep the selected compound identified so replacement does not rely on a similar color or visible outline.

Install on clean surfaces and preserve the part's natural shape while aligning it. Inspect for twisting in a ring or a folded edge in a flat gasket before closure. During service, compare the wear pattern with the mating hardware. Correct a sharp feature or unsupported region rather than choosing extra thickness that changes the closing condition across other parts of the joint.
