90 Deg Adapter Fitting #16 x 1 MPT

The 90 Deg Adapter Fitting #16 x 1 MPT from FRAGOLA is a precision hydraulic and pneumatic hose adapter designed for applications requiring a sharp directional change in fluid or air lines. This 90-degree elbow fitting connects a #16 AN (Army-Navy) male port to a 1-inch NPT (National Pipe Thread) male port, making it ideal for industrial equipment, mobile hydraulics, fuel systems, and custom fabrication projects where space constraints or system layout demands an angled connection. Technicians and fabricators rely on these adapters to redirect flow paths without compromising pressure ratings or seal integrity.

Constructed from lightweight aluminum and finished in blue anodized coating, this adapter resists corrosion while maintaining excellent strength-to-weight characteristics essential in aerospace, marine, and automotive applications. The anodized surface provides both corrosion protection and a professional appearance, while the aluminum core ensures durability under repeated pressure cycling. The 90-degree elbow geometry minimizes turbulence and pressure loss compared to multiple fittings, and the dual-thread design—AN on one end and NPT on the other—allows seamless integration between systems using different thread standards, a common requirement in retrofit and custom-build scenarios.

This fitting is essential for engineers and technicians configuring or upgrading hydraulic lines, fuel delivery systems, and pneumatic control circuits where routing flexibility is critical. The combination of #16 AN and 1-inch NPT connections suits both OEM replacement and aftermarket system design. Installation is straightforward—apply appropriate thread sealant (PTFE tape or equivalent) to NPT threads, use a wrench to tighten both ports to the system's torque specification, and verify no leakage under operating pressure. The compact 3.25 x 1.55 x 4.7-inch footprint makes it ideal for tight engine bays, equipment panels, and confined hydraulic manifold layouts.
