Topog-E® Gaskets

Topog-E® makes the original molded rubber gaskets that prolong boiler life and are available in sizes to fit every boiler.  Special sizes, water hydrant and chemical dome gasket prices are available upon request.

Topog-E® gaskets are unique in our industry.  They are molded from a special compound that will positively stop leakage that cause corrosion around handholes and manholes in steam boilers, water boilers and air tanks.

Topog-E® gaskets conform to the Topography of both surfaces.  Their unique composition is formulated and mixed at the factory.  This compound is specifically designed to provide the best resistance to the steam, heat, pressure, water and treatment chemicals of boiler applications.

This Topog-E® compound is also available in sheets.
