Neoprene Rubber O Rings
Neoprene O rings provides good resistence to UV, oxygen and weather applications. Neoprene o rings are commonly used in the refrigeration industry due to excellent resistance to ammonia and freon. Neoprene o-rings offer a range of operating temperatures Neoprene o-rings are also referred to as chloroprene o-rings or CR o-rings
