Namura gaskets are 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. The 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 fibre 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.

Steel and MLS (Multi-Layer Steel) Gaskets

No other gasket is more crucial than your head gasket. The seal between your cylinder and cylinder head is exposed to more heat and extreme pressures than anywhere else in your engine. In order to match these extreme conditions, Namura offers one of the most advanced head gaskets on the market. Constructed from multiple layers of stainless steel to resist corrosion and erosive chemicals commonly found in your engine, then using an on-off pattern, our MLS gaskets are coated/embossed with a Fluoroelastomer-based rubber to tightly seal the metallic mating surfaces. By doing this they can withstand the sheering forces created by the two surfaces (cylinder head and cylinder). This coating also enhances the bond between the gasket material and the imperfect surfaces commonly found when rebuilding your engine.

Seals and O-rings

NBR, Fluoroviton, and Silicone are selected for each application based upon the following characteristics: Temperature Resistance, Abrasion Resistance, Chemical Resistance, and their Aniline Point. A Teflon coating is applied to certain applications to prolong performance life.

Each Namura gasket is made from application-specific materials and designed for everything from top-end rebuilds to full engine overhauls. All gaskets are built to OE specifications, ensuring correct fitment with no trimming or adjustment required. Materials are tested to ASTM standards for resistance to heat, oil, fuel, and coolant, and each set is quality-checked to meet or exceed OE performance.

Features:

• AF Gasket Material: Made from a non-asbestos cellulose fibre composite bonded with NBR rubber, this material is used in clutch covers, oil pumps, coolant systems, and engine cases. It provides strong sealing, durability, and torque retention even at temperatures above 300°F.
• Steel and MLS Head Gaskets: Designed for extreme heat and pressure, Namura MLS (multi-layer steel) head gaskets use multiple layers of stainless steel for strength and corrosion resistance. A Fluoroelastomer coating improves sealing between metal surfaces and helps compensate for minor imperfections, ensuring a reliable seal under high stress.
• Seals and O-rings: Materials such as NBR, Fluoroviton, and silicone are selected based on heat resistance, wear resistance, chemical resistance, and fluid compatibility. Some applications also feature a Teflon coating to extend service life.

Crafted from military-spec certified TI3Al titanium alloy, Vertex Titanium Valves are made to endure the harshest racing conditions. Forged from a single blank, grain flow is improved to enhance the mechanical characteristics of the valve without having to resort to welding. Special PVD, CVD, and CrN coatings are used to provide low-friction surfaces that reduce heat generation and resist carbon build-up; coatings allow alloys like titanium to become ultra-smooth while reaching hardness levels 5x that of high-speed steel.

VERTEX Wrist Pin Features

Case hardened wrist pins are used with all Vertex pistons.Nitride coated pins are normally used for high performance four-stroke engines utilizing a bronze bushing or with engines using a steel connecting rod without bearings. This hardened surface is highly wear resistant and provides anti-galling properties. Nitriding is a highly specialized surface treatment that produces a highly wear resistant surface. The significant advantage of nitriding is that the surface hardness is developed without quenching and the attendant distortion problems with case hardening. Finishing operations can be eliminated or held to a minimum.
