Endura Adapter Fitting #10 to 3/8 NPT Straight

The Endura Adapter Fitting #10 to 3/8 NPT Straight is a precision hydraulic and pneumatic connector designed for professionals who demand reliable fluid or gas transfer between systems using different port standards. This straight adapter bridges the gap between #10 AN (Air-Line) male connections and 3/8 inch NPT (National Pipe Thread) male ports, making it essential for custom fuel systems, brake lines, air suspension builds, and industrial pressure applications. Whether you're fabricating a performance fuel system, assembling pneumatic tooling, or integrating aftermarket hydraulic components, this fitting provides the critical interface your system requires.

Constructed from lightweight aluminum with a protective nickel-anodized finish, the Endura adapter resists corrosion and oxidation in demanding environments while maintaining durability under pressure cycling. The nickel plating provides superior corrosion resistance compared to bare aluminum, extending service life in fuel, coolant, and moisture-exposed applications. The straight-fitting design eliminates unnecessary elbows, reducing pressure drop and simplifying installation in tight-tolerance builds where space is limited. Both the #10 AN male and 3/8 NPT male threads are precision-machined to OEM standards, ensuring leak-free seals when paired with compatible hose ends, quick-disconnects, or port adapters.

This fitting is ideal for automotive restoration shops, custom fabricators, and equipment maintenance technicians integrating legacy and modern components into unified systems. It works particularly well in fuel system conversions, air brake retrofits, and pneumatic control circuits where thread-standard mismatches are common. Weighing only 0.08 lbs with compact dimensions of 2.75 × 1.65 × 4.9 inches, it installs quickly without requiring specialized brackets or supports. Always apply thread-seal compound (PTFE tape or liquid sealant) to the NPT male thread to prevent leakage, and verify pressure ratings match your application before installation.
