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., 160
0
C,
CHO-SEAL 1224, 1298, or 1285 are
recommended. For those applications
where exposure to ���uids is a concern,
fluorosilicone materials are recommended.
