What is the primary benefit of the Viton coating on this gasket?

The Viton coating on both sides of the gasket enhances its sealing capabilities and provides excellent heat resistance, up to 482°F (250°C). This helps maintain a strong seal in demanding engine conditions.

What does 'MLS' stand for in the gasket description?

MLS stands for Multi-Layer Steel. This construction uses several layers of stainless steel to create a strong, durable, and corrosion-resistant gasket that can handle high pressures and temperatures.

Does this gasket come with any installation hardware?

This product is for the cylinder head gasket only. Installation hardware, such as head bolts or studs, is typically sold separately and should be checked for compatibility with your specific engine build.

About this part

Product Details

Starting with a multi-layer stainless steel (MLS) construction, this Cometic head gasket is built for the demanding sealing environments found in Chrysler B/RB V8 engines. The stainless steel offers increased strength and resistance to corrosion, while the multiple layers provide excellent rebound characteristics to maintain a tight seal under various load conditions. This gasket is specifically designed for a 4.500 inch bore and a thickness of .140 inches, making it suitable for a wide range of classic Mopar V8 applications, including vehicles like the Dodge Charger and Chrysler New Yorker.

The outer layers of this gasket are embossed and then coated on both sides with Viton, a high-performance synthetic rubber. Viton is known for its heat resistance, capable of withstanding temperatures up to 482°F (250°C), and its ability to conform to different surface finishes. This dual coating helps ensure a robust seal against combustion pressures and fluids, even in harsh operating conditions. This well-built gasket is a solid option for rebuilding or repairing your B/RB V8 engine.
