The Vibrant Performance Straight Adapter Fitting in -4 AN x 3/8in NP is a precision hydraulic connector designed to bridge AN (Army-Navy) and NPT (National Pipe Taper) fluid line standards in high-performance automotive and industrial applications. This adapter serves as a critical interface component for fuel systems, coolant lines, and custom fluid routing where different port thread types must be reliably connected.
Constructed from black anodized aluminum, this straight adapter fitting offers corrosion resistance and durability. The -4 AN male port accepts standard four-size AN hose ends, while the 3/8-inch NPT male thread engages directly into factory or aftermarket manifold ports, simplifying installation by eliminating the need for multiple fittings or adapters in series.
This adapter is particularly useful for fuel injection conversions and turbo coolant systems, where OEM ports use NPT threads but performance hoses employ AN fittings. Proper installation requires hand-tight seating plus 1–1.5 turns with a wrench; care should be taken to avoid over-torquing, which can damage the aluminum body.
