#6 90 Deg Fem Swivel Coupling

The #6 90 Deg Fem Swivel Coupling from XRP-XTREME RACING PROD. is a precision-engineered hydraulic fitting designed for high-performance fuel systems, cooling lines, and brake applications in modified vehicles. Built for racers, engine builders, and serious enthusiasts who demand reliability under extreme conditions, this swivel coupling eliminates hose kinking and reduces stress on adjacent components during aggressive driving or engine vibration. Whether you're assembling a custom fuel injection setup, upgrading a turbo system, or fabricating a competition-grade cooling circuit, this fitting provides the flex and durability required when every millisecond and every pound of pressure matters.

Engineered to XRP's rigorous standards, the #6 90-degree female swivel coupling features a compact design (2.7 x 1.2 x 3.7 inches) that fits tight engine bays without sacrificing flow or structural integrity. The 90-degree angle allows directional routing around obstacles while the female swivel end accommodates male-threaded hose fittings and adapters, enabling full 360-degree rotation to relieve hose torque and vibration fatigue. Manufactured from aerospace-grade materials, this coupling handles high-pressure applications—common in fuel rail systems, transmission coolers, and oil circuits—while the swivel mechanism prevents hose binding that can crack fitting seats or rupture hose assemblies under load.

Mechanics and fabricators building LS swaps, EFI conversions, or full engine bay refreshes rely on XRP swivel couplings to reduce assembly time and failure risk. The #6 size (typically -6 AN / 3/8" NPT equivalent) integrates seamlessly into medium-flow circuits where space and reliability are equally critical. Installation is straightforward—thread the male fitting into the swivel end, secure the 90-degree outlet to your line or adapter, and the swivel action immediately absorbs vibration and thermal cycling stresses that would otherwise damage conventional rigid fittings. Compatible with both steel braided hose and hard-line applications, this coupling is an essential component for any serious performance fuel, cooling, or hydraulic system upgrade.
