Endura Hose Fitting - #3an Straight

The Endura Hose Fitting #3AN Straight is a precision-engineered hydraulic and fluid line connector designed for high-performance automotive applications where reliability and durability are non-negotiable. Whether you're building a custom fuel system, upgrading cooling lines on a modified engine, or fabricating brake circuits for a track car, this straight AN fitting provides the secure, leak-free connections that serious enthusiasts and mechanics demand. As someone who has spent countless hours under the hood, you know that substandard fittings lead to slow leaks, system failures, and wasted weekends troubleshooting—this product eliminates that headache.

Constructed from steel with a nickel-anodized finish, the Endura Hose Fitting resists corrosion and oxidation in engine bays and underbody environments where moisture and road salt are constant threats. The #3AN designation indicates a nominal bore diameter suitable for moderate to high-flow applications; the straight configuration eliminates unnecessary angles that can restrict flow or create dead zones in fuel systems and coolant circuits. The nickel plating provides superior corrosion resistance compared to bare steel while maintaining excellent thermal conductivity—critical when fluid temperatures spike during sustained performance driving. The fitting threads onto both male 3AN hose ends and female 3AN ports with precision-machined surfaces that guarantee consistent, repeatable seals without galling or cross-threading.

This fitting is ideal for engine builders retrofitting older vehicles with modern fuel injection, fabricators constructing custom cooling systems, and track enthusiasts who need reliable connections in high-vibration, high-temperature environments. Installation is straightforward: hand-tighten first, then use an appropriate wrench to secure the fitting to your desired torque specification—typically 10–15 foot-pounds for 3AN fittings depending on your system pressure rating. The compact dimensions (2.65 x 1.95 x 4.95 inches) make it easy to fit into tight engine compartments and between tightly-spaced components. Compatible with any standard 3AN hose, port, or adapter, the Endura Hose Fitting integrates seamlessly into fuel systems, coolant circuits, transmission coolers, and custom hydraulic brake setups.
