#12 45 Degree Hose End Swivel

The AEROQUIP #12 45 Degree Hose End Swivel (FCM4025) is a precision-engineered hydraulic fitting designed for high-performance fuel, oil, and coolant line applications in automotive and powersports builds. This swivel adapter is essential for eliminating hose kinking and misalignment issues that often occur in custom engine bays, particularly in tight spaces where rigid plumbing can create stress concentrations.

The design features a 45-degree angle head that threads onto -12 AN (7/16-20) port fittings, a universal standard in racing fuel systems and high-flow cooling applications. Built to AEROQUIP's OEM standards, this fitting allows for full 360-degree rotation at the connection point, enabling independent hose orientation without twisting the line itself. The ball-and-socket interface is machined from aluminum alloy, which reduces weight while maintaining structural integrity under pressure cycling.

Automotive fabricators, engine builders, and bracket engineers rely on this fitting for custom fuel cell plumbing and remote-mount fuel pressure setups. AEROQUIP's precision manufacturing ensures zero leakage when mated with compatible -12 AN hoses, effectively eliminating micro-movement that can lead to chafing or ferrule damage over thousands of thermal cycles.
