Product Details

This set includes four Cometic Multi-Layer Steel (MLS) exhaust manifold gaskets, designed for Cummins 3.9L 4BT 4-cylinder diesel engines. These gaskets are built to handle the demands of high-output engines and are made from multiple layers of stainless steel for increased strength and corrosion resistance. They are ideal for sealing between aluminum and cast iron components, resisting the shearing forces that can occur between different metals.

Each gasket features an embossed outer layer coated on both sides with Viton, a heat-resistant elastomer that can handle temperatures up to 482°F (250°C). This coating is designed to perform in harsh sealing environments and under various load conditions. The center layer is uncoated stainless steel, allowing for precise thickness control. The port dimensions for this specific gasket are 2.082 inches by 1.508 inches. These gaskets are designed to seal effectively without the need for additional sealants.
