The United States Government, along with many industries world wide, has proven Copaltite an unequaled sealing agent. Wherever a packing is required against pressure, heat, cold, gases, acids, Freon, oil, benzene or gasoline, Copaltite is the premier product on the market. Under the most exacting conditions, Copaltite out performs any other product. It adheres readily to surfaces and its elasticity guarantees a perfect seal against vibration, expansion and contraction leaks. For sealing threads, flanges and other fittings exposed to high temperature and pressure, Copaltite is unexcelled.
