Below is a list of Neoprene Gaskets manufacturers from Bothell, Washington. Neoprene gaskets are made of synthetic rubber and create a long-lasting seal for gaps on machine parts in several industries. Used as an alternative to rubber and latex, these gaskets are similar to Teflon gaskets because neoprene is also an inert substance and can withstand large amounts of chemical flow without breaking down. As a result, neoprene gaskets are commonly used in the automotive industry; particularly in vehicle engines, belts and hoses.
