For refrigerant service, Durlon® offers gasket materials engineered for performance, reliability, and chemical compatibility:
Durlon® 8500 is a versatile, high-performance gasket material made from a proprietary blend of aramid and inorganic fibers. Known as our “workhorse” material, it delivers excellent sealing results in new-generation refrigerants and has successfully passed HVAC service fitness and compatibility testing.
Durlon® 8700 is the top choice for OEM-style HVAC applications, specifically designed to perform in ammonia-based refrigerants, as well as in oils and fuels. It offers a tight, durable seal for demanding refrigeration systems.
Both materials are trusted for long-term performance in HVAC and refrigeration systems where chemical resistance, pressure, and temperature stability are critical.
