Male -4AN to Male 1/4in NPT 90 Degree Fitting

The Male -4AN to Male 1/4in NPT 90 Degree Fitting from Vibrant Performance is an essential adapter for custom fuel, oil, coolant, and hydraulic line routing in engine modifications and swap projects. When space constraints or tight engine bay layouts demand directional changes without straight-run possibilities, this 90-degree adapter bridges the gap between -4AN (JIC) fittings and 1/4-inch NPT threaded ports found on manifolds, sensors, and aftermarket components.

Engineered with Vibrant's commitment to precision manufacturing, this fitting delivers the 90-degree bend at a single connection point, reducing line count and potential leak points in pressurized systems. The -4AN male side (nominal 1/4-inch OD hose) mates with standard AN hose barbs and crimp fittings, while the 1/4-inch NPT male threads cut cleanly into female ports with proper sealant application. Aircraft-grade aluminum construction keeps weight minimal—critical in performance builds—without sacrificing strength under boost, fuel pressure spikes, or thermal cycling common in forced-induction and engine-swapped vehicles.

Engine builders, turbo installers, and fuel system fabricators rely on this fitting for LS-swap fuel rail adapters, intercooler coolant lines, and custom oil feed/return setups on modified engines. Its compact design allows for easy installation in tight spaces, making it a reliable choice for various automotive applications.
