Wear resisting rubber gasket silicone rubber seal

A Wear resisting rubber gasket provides a custom seal where the mating arrangement may subject the rubber to contact movement. The joint should be designed and assembled so avoidable sliding does not damage the gasket before it reaches its working position. Material, size and color can be selected for the actual interface.

Check how the two mating parts approach one another. If one face sweeps across the gasket while closing, the rubber may drag out of its seat or develop a cut at an opening. Keep the part located without stretching and use the intended alignment and fastening sequence. Select the compound for the service medium and contact conditions rather than assuming a harder material always solves wear. During disassembly, compare marks on the gasket with the movement of the mating faces. A recurring scrape can indicate an assembly path issue. Correct that relationship and remove sharp features before fitting a new gasket, so its sealing surface remains intact when the joint is first put into operation.
