6-Hole Flange Gasket

The JAZ 6-Hole Flange Gasket (MPN 850-201-01) is a precision-engineered sealing component designed for fuel cell installations and high-performance fuel system applications. As a mechanic who has worked extensively with fuel cell fabrication and custom fuel system builds, this gasket serves a critical function: creating a reliable, leak-free seal between your fuel cell's filler neck flange and its mounting surface. Whether you're building a race car, restoration project, or off-road rig with a modern fuel cell upgrade, this six-bolt gasket eliminates the risk of fuel weeping or vapor leaks that can compromise safety and system integrity.

This flange gasket is manufactured to withstand the chemical and thermal demands of fuel contact, using materials formulated to resist gasoline, ethanol blends, and nitromethane—making it suitable for both street and racing applications. The six-hole design distributes clamping force evenly across the flange joint, preventing stress concentration and warping that can lead to mid-race failures or fuel odors in your garage. Its compact profile (measuring 4.9 x 0.3 x 5.1 inches and weighing just 0.02 lbs) ensures it fits snugly in tight engine bay configurations without interfering with adjacent components. JAZ Products' OEM-level construction means the gasket maintains dimensional consistency and surface flatness over repeated thermal cycles, essential for vehicles exposed to extreme temperature swings or high-load racing scenarios.

This component is ideal for custom fuel cell installations, vintage hot rods equipped with modern fuel cell systems, and race car builders who demand OEM-quality reliability without compromise. Installation is straightforward: position the gasket between the fuel cell flange and mounting surface, align the six bolt holes, and torque fasteners in a star pattern to ensure even seating. The gasket's proven durability makes it a trusted choice among professional fabricators and weekend enthusiasts alike. For any builder planning a fuel cell swap or fuel system upgrade, the JAZ 6-Hole Flange Gasket provides the peace of mind that your fuel delivery system won't leak, fail, or create safety hazards on the street or strip.
