Gasket Material

When fittings are installed on polyethylene plastic storage tanks, a gasket is almost always required to insure against leaks. Gaskets are made from several different materials and the decision to use one kind over another is based on the chemical resistance properties of the substance that will be stored in the tank.

The following table is based on recommendations from gasket companies. It is provided for your convenience only. Bailiff Enterprises makes no guarantees or warranties regarding the correctness of this information. Contact us directly for specific application recommendations.
