Topoge Boiler Gaskets

Topog-e® boiler gaskets

The Best Reputation. For over forty years, Topog-E® Series 180 gaskets have earned a reputation for ease of use, durability, unbeatable performance and overall quality.

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.
  • Temperaures to 350°F
  • Pressures to 180PSI
  • No Corrosion
  • Size Easily Identified
  • Good Shelf Life
