#3 AN Tee Fem Swvl On Run

The A-1 Products #3 AN Tee Female Swivel on Run is a precision adapter fitting designed for high-pressure fluid systems in marine, aircraft, and industrial hydraulic applications. This aluminum tee fitting features a 3 AN female swivel port on one branch and dual 3 AN male ports, allowing versatile directional flow control in confined engine compartments and plumbing layouts where space demands a compact solution.

Constructed from aluminum and finished in blue anodize, this adapter combines lightweight durability with corrosion resistance—critical for saltwater and humid marine environments where steel fittings degrade quickly. The swivel female end accommodates hose connections with rotational freedom, reducing stress on attached tubing during vibration and thermal cycling. The 3 AN port size handles flows compatible with standard -3 hose and tubing, making it ideal for fuel, coolant, and lubrication circuits in engines rated for moderate to high-pressure delivery.

Boaters restoring or upgrading cooling and fuel systems benefit from this tee's compact footprint and the swivel connection's ability to angle hoses without kinks or fittings stress. Motorsport and performance engine builders use similar configurations to branch secondary coolant or fuel lines to auxiliary gauges and overflow reservoirs. Aircraft and automotive technicians rely on AN-standard fittings for their precision engineering and interchangeability across platforms.
