Rubber Gasket Rubber is the most cost-effective material to use where temperatures and pressures are low and the chemical environment is mild. Different elastomers offer different mechanical and chemical properties. Cloth inserted materials are better able to handle movement and high compression loads. Rubber Gaskets are die cut or circle cut from different types of rubber materials. Technical Specifications
