Interstate-McBee has been manufacturing gaskets for over 15 years using the highest quality raw materials available for diesel and natural gas engines, including Caterpillar®, Cummins®, Detroit Diesel®, Navistar®, and Waukesha® applications.


The correct material for the specific application ensures the gasket will perform without compromising its functionality and seal ability. Proper material selection will depend upon temperature variations, pressure, and contact with a variety of fluids and surfaces.
Interstate-McBee uses over 30 base materials to achieve superior performance
for our entire line of gaskets and sealing products.
Our made in the USA sealing products use 100% Asbestos-Free Material
