#3 Str Female Swivel to 1/8 MPT Fitting Steel

The #3 Str Female Swivel to 1/8 MPT Fitting Steel (XRP900631) is a precision hydraulic adapter designed for high-pressure marine and boating applications where reliable fluid transfer is critical. Built by XRP-Xtreme Racing Products, this straight fitting bridges AN3 female swivel connections to standard NPT male threads, making it essential for fuel systems, hydraulic lines, and cooling circuits on performance boats and marine engines.

Constructed from durable steel and featuring a nickel-plated finish for enhanced corrosion resistance, this adapter is designed to withstand harsh marine environments. The female swivel end accepts AN3 hard-line tubing, while the 1/8-inch NPT male end threads directly into engine blocks, manifolds, or auxiliary equipment. The swivel design allows for hose or tube connection without twisting, reducing installation stress and preventing leaks.

This fitting is ideal for boaters upgrading fuel delivery systems, installing aftermarket gauges, or connecting auxiliary hydraulic lines on custom or rebuilt marine engines. Its compact design (2.75 x 0.95 x 3.65 inches) fits tight engine bays and transom installations, ensuring compatibility with various setups. Anglers and boaters running modified or high-output powerplants depend on fittings like this to maintain system integrity under demanding conditions on the water.
