Swivel Union Female -3 to Female -3

The Swivel Union Female -3 to Female -3 from ALLSTAR PERFORMANCE is an essential fluid transfer fitting for high-performance automotive systems where flexible hose connections demand reliable, leak-free joints. Designed for mechanics and enthusiasts building custom cooling, fuel, or transmission line configurations, this adapter eliminates rigid piping constraints and allows angle adjustments critical in tight engine bays or complex plumbing layouts.

This swivel union features female -3 AN (dash-3) ports on both ends, enabling 360-degree rotation to accommodate hose routing without stress or kinking. The -3 designation corresponds to 3/16-inch inner diameter tubing, making it ideal for lower-pressure cooling or brake applications where weight savings and compact fitment are priorities. ALLSTAR PERFORMANCE's precision manufacturing ensures minimal internal turbulence and consistent thread seals, reducing vibration-induced leaks common in amateur installations.

The lightweight construction—at just 0.03 pounds—keeps suspension unsprung weight minimal while maintaining the structural integrity needed for engine compartment temperatures and modest pressure cycles. This fitting is essential for racers, fabricators, and street enthusiasts upgrading cooling systems, as it provides the flexibility and reliability needed for various applications.
