Buying advice

When buying automotive performance hose fittings and adapters, prioritize AN compatibility and material (aluminum for weight, steel for durability). Check thread sizes and hose type (push-loc, reusable, etc.). For street use, mild steel or aluminum fittings suffice; for racing or high-pressure, opt for swivel or double O-ring designs. Always verify thread pitch and ensure you have the correct hose ID for push-on fittings.
