About this product
Achieve unparalleled engine sealing and optimize performance with the Cometic Multi-Layer Steel Cylinder Base Gasket. Engineered for demanding motorcycle applications, this advanced gasket ensures a reliable seal where it matters most, preventing leaks and maintaining consistent engine pressure for peak power output.
Description
The Cometic Multi-Layer Steel (MLS) Cylinder Base Gasket represents the pinnacle of sealing technology, designed to withstand the harshest engine environments. Its innovative construction features a robust center or shim layer crafted from uncoated stainless steel, allowing for precise thickness adjustments to meet specific engine requirements. The outer layers are meticulously embossed and coated on both sides with Viton, a high-performance fluoroelastomer known for its exceptional resistance to extreme temperatures, chemicals, and oils. This dual-sided Viton coating ensures superior sealing integrity under varying load conditions and surface finishes, providing a long-lasting and dependable seal for your motorcycle engine.
Cometic's MLS gasket technology utilizes Load Control Embossments (LCE) to promote an even torque load across the entire gasket sealing surface. This critical design feature significantly reduces bore distortion, leading to a better piston ring seal and ultimately, more power and improved engine efficiency. With a precise thickness of 0.25 mm (0.010"), this rubber-coated steel gasket is manufactured with uncompromising quality right here in the USA, offering a premium solution for high-performance engine builds and critical replacements.
