Yamaha WR450F, YZ450F & More Namura Full Gasket Set

Quality materials mean increased longevity and continued performance. A critical aspect of any rebuild, gaskets are often given little thought. However, the right materials can make all the difference.

Manufactured from materials specifically chosen for each individual application. From top-end sets to complete kits for a full teardown, you can be sure that Namura gaskets are up to the task at hand.

Namura gaskets are manufactured to OE-specs, which means no trimming or fitment issues. Our materials are explicitly selected for their temperature, oil, fuel, and coolant-resistant qualities as well as tested using ASTM standards. Each design is evaluated against rigid quality-control standards to ensure each set meets or exceeds OE performance. Clutch gaskets are available for certain applications.

AF Gasket Material

Made from a high-quality, non-asbestos cellulose fiber composite bonded with Nitrile Butadiene rubber (NBR), this gasket material is ideal for clutch covers, oil pumps, coolant systems, and other engine case applications. It maintains excellent tensile strength, sealing integrity, and torque retention—even in continuous temperatures exceeding 300ºF.

Engineered for durability, it offers reliable performance in high-stress environments where fluid resistance and heat tolerance are essential.
