High temperature resistant rubber sealing gasket

A high temperature resistant rubber sealing gasket forms a flexible interface between mating surfaces exposed to heat. Its compound, thickness and retained outline need to suit the joint at working temperature as well as during initial assembly. Custom size and color options allow the part to follow the sealing location.

Identify how heat reaches the gasket and how long it remains present. A brief warm process and continuous contact with a heated surface are different conditions. Include the fluid or gas at the joint and any cleaning exposure when selecting the finished rubber. The material family alone should not be used as a universal temperature limit.

Assemble the gasket on clean, supported faces and avoid stretching it to align the openings. Check the seal in the complete operating arrangement, including warming and cooling where relevant. Once it is safe to inspect, examine for a shifted edge, local hardening or a permanent uneven profile. If the joint is reopened, correct damaged seating surfaces before replacing the gasket. Increased tightening should not substitute for a suitable material and the intended compressed geometry.
