Premier North American Fabricator

Sealing Devices is a premier North American manufacturer of gaskets offering a variety of different methods to produce gasket products. Our manufacturing facility includes over 200-pieces of equipment and in-house tooling and die-making, which allow us to make gaskets from commercial and mil-spec rubber, compressed sheet gaskets, cloth inserted gaskets, paper, fabric, felt and most any other material with quick cut options.

What is a Gasket?

Gaskets seal between two different surfaces under compression. Sealing Devices is an expert manufacturer of gaskets produced from all materials. Gasket sealing is a result of compressive forces created by sufficient bolt load and works to fill the imperfections on the mating surfaces to be sealed. (ANSI Flange Standards)
