Straight Adapter Fitting #4 x 3/8 MPT Black

The Straight Adapter Fitting #4 x 3/8 MPT Black from FRAGOLA is a precision hydraulic and fuel system connector designed for applications requiring a secure transition between 4 AN male ports and 3/8 inch NPT male connections. This fitting is ideal for professionals and enthusiasts working on high-performance fuel systems, hydraulic lines, and custom automotive builds where reliable, leak-free connections are essential.

Constructed from aluminum with a black anodized finish, this adapter combines lightweight durability with corrosion resistance and a professional appearance. The 4 AN male end accommodates standard hose fittings and adapters common in race fuel systems and aftermarket hydraulic applications, while the 3/8 inch NPT male port threads directly into manifolds, regulators, and block ports using standard pipe thread specifications.

This fitting is particularly beneficial for technicians upgrading fuel delivery systems, installing aftermarket fuel pressure regulators, or adapting legacy hydraulic components to modern AN hose standards. The straight configuration eliminates unnecessary bends and pressure points, reducing turbulence and potential leakage under high-flow conditions. Basic wrenching is all that's required for installation, ensuring a straightforward process.
