Straight Adapter Fitting #8 x 3/8 MPT

The Straight Adapter Fitting #8 x 3/8 MPT is a precision hydraulic and pneumatic adapter designed to connect AN-sized hose systems to NPT-threaded ports and components. Whether you're building a custom fluid transfer system, restoring a classic vehicle's brake or fuel line configuration, or assembling industrial pneumatic equipment, this straight adapter provides a leak-free transition between incompatible thread standards. Its compact design minimizes turbulence and pressure drop, making it ideal for applications where flow efficiency and reliability are non-negotiable.

Constructed from aluminum with a blue anodized finish, the Straight Adapter Fitting #8 x 3/8 MPT delivers corrosion resistance and a professional appearance suitable for both engine bay and display-quality builds. The blue anodize coating protects against oxidation and UV degradation while maintaining a lightweight profile at just 0.04 lbs. The fitting uses industry-standard 8 AN male threads on one end and 3/8 inch NPT male threads on the other, ensuring compatibility with both modern automotive fuel injection systems and traditional NPT-based industrial equipment. Straight-flow geometry eliminates elbows, reducing connection points and potential failure sources in high-vibration or high-pressure environments.

This adapter is essential for custom fuel system builds, aftermarket turbo installations, pneumatic tool setup, and vintage vehicle restorations where original NPT ports must interface with modern AN-line components. Technicians and fabricators rely on FRAGOLA's precision engineering to eliminate cross-threading and ensure repeatable, secure connections across multiple installations. The adapter's compact 1.55 x 0.95 x 4.05 inch footprint fits tight engine compartments and compact machinery enclosures. Always use appropriate thread sealant or tape on NPT threads and torque connections to manufacturer specifications to guarantee optimal flow and pressure retention in your system.
