#10 ORB x 3/8 MPT Adapter Fitting Black

The FRAGOLA #10 ORB x 3/8 MPT Adapter Fitting in black is a straight adapter designed to connect -10 AN male O-ring boss ports to 3/8-inch NPT male threads. Built from aluminum and finished in black anodize, this fitting bridges two of the most common hydraulic and pneumatic port standards found in high-performance fluid systems, making it an essential connector for custom installations across automotive, marine, and industrial applications.

The -10 AN O-ring boss (ORB) configuration on one end meets the NPT male thread on the other, allowing you to mate systems that would otherwise require separate adapters or reducers. The black anodized aluminum construction provides corrosion resistance while keeping weight minimal—essential in performance applications where every pound matters. The straight geometry ensures direct flow paths without the restrictions or turbulence that elbows or offset fittings introduce. At just 0.05 lbs, this adapter adds negligible weight to your assembly while maintaining full structural integrity under pressure.

This fitting is ideal for custom fuel systems, air suspension setups, hydraulic brake lines, and pressurized cooling systems where precision port compatibility is non-negotiable. Technicians and builders working with mixed AN and NPT infrastructure benefit from FRAGOLA's reputation for exact dimensional standards and reliable sealing. The adapter integrates seamlessly into existing manifolds, filter heads, or remote reservoirs that combine older NPT designs with modern AN plumbing. Whether you're fabricating a race fuel cell, upgrading turbo boost lines, or assembling a custom auxiliary cooling circuit, this straight adapter eliminates the need for improvised solutions or mismatched port geometry.
