GASKET SHEETS

PRODUCT DESCRIPTION

Gasket material selection is critical. To perform their function, gaskets are expected to be compressible and resilient. After all, the purpose of a gasket sealant is to compensate for the unconformity of mating surfaces (surface irregularities). These irregularities may be minute or large. The gasket material may need to limit the flow of gas or fluids through the
