Neoprene Full Face Gasket

Full Face gaskets are a flat sealing element, consisting of an inner and outer diameter, and a specified number of bolt holes, the center of which are evenly spaced around a bolt circle. Full face gaskets are designed to fill the entire space between flat-faced flanges, with bolt holes that match the size and arrangement of the bolt holes in the intended flanges. ASME B16.21 and ASME B16.47 govern the dimensions of full face gaskets for standard and large diameter pipe flanges. Neoprene offers good resistance to oil and petroleum base solvents and excellent resistance to dilute acids. Known by the chemical name chloroprene, 60 durometer neoprene is made from 100% neoprene and is suited for various applications while giving users a gasket material with excellent weathering and ozone resistance.
