Adapter Fittings -4 to 7/16-20 90 Degree 2pk

The Adapter Fittings -4 to 7/16-20 90 Degree 2pk from ALLSTAR PERFORMANCE delivers reliable pressure-line adaptation for high-performance fuel, oil, and coolant systems. This two-pack adapter set is engineered for builders, mechanics, and enthusiasts who demand precise fitting transitions in tight engine compartments. The 90-degree configuration allows space-efficient routing where straight connectors would create clearance conflicts or awkward line runs.

Each fitting features a -4 AN (7/16-20) male inlet that accepts standard -4 AN hose and fittings, while the outlet connects to 7/16-20 threaded ports found on engines, coolers, and block accessories. Manufactured from steel and finished with zinc oxide plating, these adapters resist corrosion in engine bay environments while maintaining structural integrity under fuel system pressures. The O-ring seal design ensures leak-free performance without requiring PTFE tape or additional sealant compounds, critical for fuel and oil circulation systems where contamination cannot be tolerated.

Street and drag racing platforms benefit from this two-pack configuration, allowing upgrades to fuel pressure regulators, bypass blocks, or remote oil filtration without fabricating custom adapters. Installation is straightforward—thread the -4 AN hose end onto the inlet port using standard -4 AN wrenches, then screw the outlet fitting directly into the 7/16-20 tapped hole. Weight at 0.15 lbs per pair keeps impact on overall vehicle mass negligible, making these adapters ideal for weight-conscious builds where every pound matters.
