Product Details
If you're working on a Jaguar with an AJ26, AJ27, AJ33, or similar engine, this Multi-Layer Steel (MLS) cylinder head gasket from Cometic is built to seal things up tight. It's specifically designed for the right-hand side (RHS) of the engine and has a 93mm bore with a compressed thickness of .040 inches. This gasket is a solid option for a wide range of Jaguar models, including the S-Type, XJ8, and XK8, among others.
Cometic's MLS design uses multiple layers of stainless steel, which gives it increased strength and the ability to rebound, helping it withstand the forces created when mating aluminum heads to cast iron blocks. The outer layers are coated with Viton, a heat-resistant rubber material that can handle temperatures up to 482°F (250°C) and works well in tough sealing environments. This construction means the gasket doesn't require any additional sealants, making installation more straightforward.
