Welcome to Learning About Neoprene-Faced Phenolic Flange Isolation Gasket
The neoprene-faced phenolic flange isolation gasket has always been used as a standard isolation gasket in the water, gas and oil industries due to the soft neoprene rubber giving excellent sealing efficiency. For this type of gasket, it is made of soft neoprene rubber that is covered to either side of a phenolic gasket to supply an effective sealing performance and high electric resistance. Its working temperature is maximum to +79°C.
