Cometic Thermostat Housing Gasket – Dodge 5.7L / 6.1L HEMI

The Cometic C5198 Thermostat Housing Gasket is a premium molded rubber gasket designed for Dodge, Chrysler, Jeep, and Ram vehicles equipped with 5.7L and 6.1L HEMI engines. Manufactured from soft durometer rubber formed specifically to the sealing surface, this gasket provides superior sealing and extended reusability compared to traditional cork or paper gaskets. It is the ideal replacement for maintaining a leak-free thermostat housing on stock or performance HEMI builds.

  • Molded Rubber Construction – Soft durometer rubber formed to the exact sealing surface for superior sealing
  • Steel Torque-Limiting Frame (where applicable) – Enhances rigidity and reusability while preventing over-tightening
  • High-Temperature Resistance – Withstands engine coolant temperatures and thermal cycling
  • Direct Fit – Exact replacement for the factory thermostat housing gasket
