#10 45 Degree Hose End Swivel

The #10 45 Degree Hose End Swivel is a precision-engineered hydraulic fitting designed for high-performance fuel, oil, and coolant line applications in modified and race vehicles. Built by AEROQUIP—the OEM standard trusted by professional mechanics and serious enthusiasts—this 10 AN adapter delivers the directional control and leak-free reliability demanded by turbocharged builds, LS swaps, and custom engine bays where space constraints and hose routing complexity require angled connections.

This 45-degree swivel fitting connects a 10 AN hose to a 10 AN female receiver with a 360-degree rotating collar, eliminating stress on hose ends and preventing fluid leaks caused by vibration-induced twisting. The aluminum construction with blue and red anodized finish provides superior corrosion resistance while maintaining visibility under the hood—critical for identifying fuel, coolant, or oil circuits at a glance. The swivel design accommodates tight engine bay geometries without kinking or crimping the hose, preserving flow integrity in fuel-injection systems and pressurized cooling loops where even minor restrictions trigger performance loss.

Mechanics and engine builders rely on this fitting for LS, small-block, and big-block conversions, custom fuel systems, and retrofit turbo installations where OEM hard lines are replaced with flexible AN hose for heat management and installation freedom. The 45-degree geometry works where 90-degree elbows won't fit and straight adapters won't align—common scenarios in tight engine bays and transmission tunnel configurations. Weighing just 0.21 lbs and measuring 3.5 x 1.8 x 5.25 inches, it integrates seamlessly into compact builds without adding bulk while maintaining AEROQUIP's reputation for zero-failure hydraulic connections under sustained pressure and thermal cycling.
