AN Fittings, Hose Ends & Fluid System Fittings

AN (Army-Navy) fittings are the standard for high-performance fluid plumbing, providing leak-free, reusable connections for fuel, oil, coolant, brake, and air systems. AN fittings use a 37-degree flare seal and come in a full range of sizes, configurations, and materials to plumb any fluid system on a performance build.

OneFastShop carries a massive selection of AN fittings including straight, 45-degree, 90-degree, and 120-degree hose ends, AN adapters, AN tees, AN unions, AN bulkhead fittings, AN-to-NPT adapters, AN-to-metric adapters, push-lock fittings, and fittings in aluminum and stainless steel across all popular AN sizes from -3AN to -20AN.

Every fitting at OneFastShop ships brand-new and ready to assemble. Whether you're plumbing a complete fuel system, building custom oil lines, or running braided coolant lines, OneFastShop has every AN fitting and adapter you need. Shop the full fittings collection today.
