Rubber Exhaust Gasket Rectangle Heat Resistant Gasket

A Rubber Exhaust Gasket with a rectangular form must be matched to the specific joint and the exposure at that location. Exhaust-related assemblies can have very different thermal conditions, so the rubber construction should be selected from the actual surface temperature, medium and duration of contact. The name alone does not establish suitability for direct engine exhaust gas.

Match the outline, internal passage and thickness to the supported mating faces. Corners and fastening areas should align without stretching the gasket into place. Select the compound for the joint's temperature and chemical conditions, then evaluate the complete installed seal. Where heating and cooling occur, include those stages when assessing fit. Once the assembly is safe to open, inspect the gasket for hardening, cuts or a locally crushed region. A rectangular edge pushed outside its supporting face can be damaged even if the rest of the seal remains intact. Correct the mating or thermal issue before fitting a replacement rather than applying extra tightening to a deteriorated gasket.

Material options

Rubber. Custom formulation and color for the intended contact conditions.

Hardness selection

Custom dimensions

Match the outline, internal passage and thickness to the supported mating faces.

Fit & assembly

A rectangular edge pushed outside its supporting face can be damaged even if the rest of the seal remains intact.

Use & inspection

Correct the mating or thermal issue before fitting a replacement rather than applying extra tightening to a deteriorated gasket.
