Specifications

EXHAUST GASKET SET

Cometic HTS exhaust gaskets are constructed from multiple layers of strong stainless steel that has excellent rebound ability and corrosion-resistant characteristics. Outer layers are coated with a heat-resistant, graphite-based material to create a superior-quality seal that can withstand a variety of sealing and load conditions and surfaces.

Rated for 1400 degrees F, these gaskets are perfect for small engine and turbocharged applications. Cometic HTS exhaust gaskets are ideal for all types of head and block material—and their design promotes an even torque load across the sealing surface, allowing for measurably reduced bore distortion. Order the gaskets recommended for your application.
