Molded heat-resistant EPDM rubber solid stoppers/plugs

EPDM rubber solid stoppers can be custom molded for an opening whose environment includes heat exposure. Select the finished EPDM compound according to the actual temperature, duration and contacting medium. The closure profile should still match the opening's working seat and the space available behind it.

Evaluate the stopper under the conditions it will encounter rather than checking only a room temperature fit. Repeated heating and cooling may be part of the application, and the assembled closure should be assessed through that sequence. Ensure the exposed area remains suitable for the intended handling method.

Before installation, clear the mating surface of burrs and residue. Fit the solid body without puncturing it or forcing it past an internal obstruction. During maintenance, inspect for a changed shape, surface damage or a seating position that differs from the intended one. Review material suitability and local exposure if these changes recur. Greater insertion force should not be used to compensate for a stopper that no longer maintains its designed profile.

Material options

EPDM compound options, customized alongside the profile and contact conditions.

Hardness selection

Solid rubber options: 30–90 Shore A. Fit the solid body without puncturing it or forcing it past an internal obstruction.

Custom geometry

The closure profile should still match the opening's working seat and the space available behind it.

Fit evaluation

Evaluate the stopper under the conditions it will encounter rather than checking only a room temperature fit.
