Extending the use of our patent pending molding technology, the 3504 TUFF-RAIL® gasket is the latest addition to our TUFF-RAIL® family of products. A blend of aluminosilicate and PTFE, the 3504 TUFF-RAIL® offers excellent compressibility and a wide range of chemical compatability. Engineered with the same raised sealing areas, the 3504 TUFF-RAIL® has been proven to seal and reseal even in the most demanding manway installations.
