Corrosion Resistant Neoprene Rubber CR O-Ring

Neoprene is a multi-purposed elastomer which yields a balanced combination of properties. Neoprene o-rings are typically seen in the refrigeration sector, as they demonstrate remarkable resistance to chemicals such as ammonia and a variety of coolants.

Neoprene o-rings also perform well in contact with oils and many chemicals and has good resistance to sun, ozone and weather. The material displays outstanding toughness and good resistance to fire. 

This, combined with a broad temperature range and moderate cost, accounts for its desirability in many sealing applications for refrigerants like Freon® and ammonia. CR is resistant to refrigerants, ammonia, Freon®, silicone oils, water, ozone, vegetable oils, alcohols, and low-pressure oxygen.
