Topog-E® Boiler Gaskets 
Topog-E® is the original molded rubber gasket for steam, water, or air use on boilers, water tanks, and air tanks that use pressures to 180 PSI and temperatures to 380°F. Topog-E° gaskets conform to the topography of both surfaces to seal immediately. Each batch of rubber compound is rigidly laboratory tested for strength and endurance to exceed conditions under which a boiler must operate. For quick, accurate identification, the size and shape is permanently molded into each Topog-E° gasket.
