GASK gaskets are made from EPDM. EDPM is a very durable
material with superior resistance to ozone, UV light, and
temperature variations. An EPDM gasket can withstand
temperatures from -30˚C to +100˚C.
All GASK gaskets should be fitted and held tight in the fitting's
hemmed rim. GASK gaskets provide fully sealed and durable
joints. If installed as recommended, GASK gaskets provide
superior air tightness class D (Certificate no. 0103/07 according
to PN-EN 12237).
