#3-#3 Female/Female Swivel Union

The #3-#3 Female/Female Swivel Union from Triple X Race Components is an essential hydraulic or fluid line connector for high-performance automotive builds, race cars, and custom engine bay setups. This fitting serves as a junction point where two hoses or lines meet, allowing controlled flow between fuel systems, cooling circuits, or hydraulic brake lines. Whether you're building a fuel cell setup, custom cooling loop, or modular brake system, the swivel design of this union eliminates the need for separate adapter fittings and reduces potential leak points in your plumbing.

Engineered with a swivel connection mechanism, the #3-#3 Female/Female Union allows 360-degree rotation at the fitting joint, making installation and maintenance significantly easier in tight engine compartment spaces. The female-to-female configuration means both hose ends connect using standard male adapters, simplifying your parts inventory and compatibility across different hose sizes and materials. Triple X Race Components manufactures this fitting to withstand the vibration, temperature cycling, and pressure demands of competitive motorsports and street performance applications, ensuring reliable sealing without constant re-tightening.

This compact union (weighing just 0.03 lbs) fits seamlessly into cramped engine bays where every millimeter counts—ideal for bracket-mounted fuel regulators, intercooler plumbing, and modular cooling systems on LS swaps, turbocharged builds, and dedicated race vehicles. The #3 size designation matches standard AN3 hose and fitting standards used throughout the automotive aftermarket, ensuring straightforward compatibility with Aeroquip, Parker, and other quality hose manufacturers. Installation requires only wrenches or a hose crimping station if you're running custom lines; the swivel head prevents over-torquing damage to surrounding components during final assembly.
