Neoprene Ring 1/16" 150# Gasket
Neoprene or polychloroprene is a family of synthetic rubbers that are produced by polymerization of chloroprene. Neoprene exhibits good chemical stability and maintains flexibility over a wide temperature range.
Our standard gaskets conform to the sizes set forth by the ASME, as shown below.
