Nylon Float Bowl Screw Gaskets (18)

The Nylon Float Bowl Screw Gaskets (18) from Advanced Engine Design are precision-engineered seals designed specifically for Holley carburetors and compatible fuel bowl applications. As a mechanic rebuilding or restoring classic and high-performance engines, you understand that fuel system integrity depends on reliable gasket materials that resist fuel degradation and maintain consistent sealing over thousands of heat cycles. This 18-piece set ensures you have spares on hand for multiple carburetors or future rebuilds, eliminating downtime when float bowl screws need attention.

Each gasket features a 0.219-inch inner diameter with a precise 0.063-inch thickness, engineered to compress uniformly and create an airtight seal around float bowl fasteners without pinching fuel lines or restricting flow. The nylon construction resists ethanol-blend fuels and temperature extremes better than natural rubber, making these gaskets ideal for both street and competition applications where fuel chemistry and engine bay heat pose challenges to inferior sealing materials. The consistent dimensional tolerance ensures proper bolt torque distribution and prevents fuel seepage that could contaminate oil or create fire hazards.

Professional rebuilders, restoration shops, and serious enthusiasts benefit most from stocking these gaskets during carburetor overhauls, fuel system upgrades, or routine maintenance intervals. Installation is straightforward—simply place the gasket under the float bowl screw head before torquing to manufacturer specification, ensuring the nylon compresses evenly for maximum sealing life. These gaskets are compatible with Holley carburetors of various displacement and configuration, making them an essential consumable for any shop managing multiple platform builds or restorations.
