connector gaskets

Parker Chomerics provides several types of connector gaskets, such as mounting flange connectors, interfacial seals, jam nut seals, flat washers, D-subminiature rectangular connectors, O-Rings and D-Rings. All of these connector gasket are available in most of our CHO-SEAL conductive elastomer material types. For applications to continuous high temperature exposure, e.g., 1600 C, CHO-SEAL 1224, 1298, or 1285 are recommended. For those applications where exposure to fluids is a concern, fluorosilicone materials are recommended.

The most common connector seal materials are:

CHO-SEAL 1224, silver filled silicone
CHO-SEAL 1215, silver-plated copper filled silicone
CHO-SEAL 1285, silver-plated aluminum filled silicone
CHO-SEAL 6502, nickel-plated aluminum filled silicone
CHO-SEAL 1298, silver-plated aluminum filled fluorosilicone
CHO-SEAL 6503, nickel-plated aluminum filled fluorosilicone
CHO-SEAL L6303, nickel-plated graphite filled fluorosilicone
