Product Details
Cometic Gasket is known for making well-built sealing components, and this Multi-Layer Steel (MLS) head gasket is a prime example. If you're working on a high-output engine like those found in your Jaguar XK120, XK140, XK150, Toyota Cressida, or Supra, you need a gasket that can handle the pressure. This gasket is designed to provide maximum sealing performance without needing any additional sealants, making the job a bit simpler.
This gasket is constructed from multiple layers of stainless steel, which gives it increased strength and the ability to rebound, helping it resist corrosion. The outer layers are embossed and coated on both sides with Viton, a heat-resistant rubber material that can handle temperatures up to 482°F (250°C). This makes it suitable for sealing environments with varying load conditions and surface finishes, and it can handle the shearing forces between aluminum heads and cast iron blocks. The center layer is stainless steel and can be varied in thickness to meet different requirements; this particular gasket has a compressed operating thickness of 0.036 inches and an 84mm bore, with an overall thickness of 0.045 inches.
