#10 Straight Theaded Plu

The #10 straight threaded plug from XRP-XTREME RACING PROD. is a purpose-built hydraulic and fuel system fitting designed for high-performance automotive applications. Built for racers, engine builders, and serious performance enthusiasts, this aluminum plug seals AN-spec ports with precision and reliability. Whether you're assembling a custom fuel system, setting up a high-flow cooling circuit, or completing a race-spec engine platform, a quality threaded plug is essential infrastructure for systems operating under pressure.

This #10 AN fitting features an O-ring sealed design that creates a robust, leak-free connection without relying on crush washers or tape. The blue anodized aluminum construction offers corrosion resistance and a professional appearance in engine bays and fuel compartments, while the hex head design accommodates standard wrenches for straightforward installation and future service. The straight threaded port accepts direct hose connections or additional fittings, making it ideal for block-offs, drain ports, or dead-end terminations in your hydraulic or fuel line routing. O-ring sealing technology provides superior reliability compared to older NPT tapered designs, especially in mobile applications subject to vibration and thermal cycling.

Mechanics and fabricators working with XRP systems benefit from the compatibility of this plug with existing #10 AN hose, fittings, and block assemblies. Its compact footprint (2.7 × 1.2 × 3.9 inches) fits tight engine bays and custom manifold layouts without demanding excessive clearance. Installation is straightforward: hand-tighten the O-ring seated fitting, then wrench-torque to secure the hex head—no tape, no guesswork. Perfect for LS swaps, fuel system upgrades, cooling system builds, or any modern racing platform requiring AN-standard plumbing solutions for sale or custom builds.
