The Metal Tech Hi-Tex series features our specially designed starburst core tang technology. This robust metal core, available in carbon or stainless steel, provides optimum strength for the laminate in the most demanding applications. The starburst pattern provides 3-4 contact points around the tang and a columnar shape, providing excellent load retention and crush resistance. This technology is best used for high temperature or high load applications such as engine exhaust systems, where sufficient flange loading is available and load retention is required. Generally, the grades in this series are designed for applications such as exhaust manifolds, turbocharger applications, exhaust system gaskets, head gaskets, general industrial flange applications, etc.


HT 142 – Economy graphite

Provides an economical solution where graphite gasketing is required.

HT 195 – Globally sourced performance laminate

Anti-oxidant graphite applied to starburst-style core. OEM performance at an economical price.

HT 908 – Proven domestic graphite

An excellent all-around sealing material typically used for engine cylinder head and exhaust gaskets, industrial flange gaskets, along with numerous others.

HT 959 – Oxidation-resistant graphite

Recommended for OEM exhaust flange gasket applications and other performance-driven uses that require long-life sealing.

High temperature fiber

HT 337 – Durable graphite/fiber blend

Universal material that can be used in a variety of applications including: sealing intake and exhaust, cylinder heads, high pressure/temperature engine ports, and high performance turbo charger environments in engines from large diesels to lawn and garden uses.
