MDP Billet Aluminum AN Fittings

MDP Billet Aluminum AN Fittings Built with purpose. Engineered by enthusiasts. MDP – Innovators, Not Imitators. Stop marring your custom engine bay components during installation. The new MDP Billet Aluminum AN Fittings are engineered with an extended wrench-flat area, giving you ample clearance for a standard AN or 22mm wrench. Tighten your lines with absolute confidence, keeping your high-dollar fuel rail and valve cover entirely scratch-free. Inside, these fittings feature a proprietary velocity-style internal bore that eliminates restrictions and smooths out fluid turbulence, ensuring maximum flow efficiency where your fuel system needs it most. Performance Specs: The Material: Precision CNC-machined from lightweight, corrosion-resistant 6061-T6 billet aluminum. The Threads: 10 ORB (O-Ring Boss) male inlet to -6AN, -8AN, or -10AN male flare outlets. The Clearance: Extended flats prevent wrench slippage and protect neighboring components.
