Below is a list of Die Cut Gasket manufacturers from Bloomfield, Connecticut. Die cut gaskets are ring-shaped sealants that create a tight seal between two mating parts to prevent liquids or air from leaking out. Any device or machine that confines gas or liquid has die cut gaskets, which compensate for non-conformity between two mating surfaces. Since all gaskets have thinner, flat profiles, most are manufactured through the die cutting process, which uses sharp metal dies or CO2 lasers in a cookie-cutter style cutting method.
