Why Use a Tee Fitting Adapter?

AN tee fittings allow builders to split fluid flow between multiple components such as fuel pressure regulators, gauges, auxiliary systems, catch cans, or secondary fuel rails. The integrated swivel design also improves installation flexibility while reducing hose twist during assembly.

Translation: fewer crossed threads, fewer stripped fittings, slightly less emotional damage.

[Size] The thread size of 6an is nine/sixteen-18 UNF.

[Sealing] The AN thread of the flare is sealed by means of a 37 degree attitude.

Swivel Design Improves Installation

The integrated female swivel connection allows easier hose alignment during installation, reducing stress on braided lines and helping maintain a cleaner routing layout. This is especially useful in tight engine bays where traditional rigid fittings can complicate hose positioning.

Basically designed for engine bays where every fitting is somehow one millimeter from disaster.

[Material] Product of 6061-T6 aluminum, anodized black surface.

Built for High-Performance Systems

The full-flow internal design supports high-volume fuel and fluid delivery required by turbocharged, supercharged, and high-horsepower applications. Compatible with modern AN plumbing systems, this fitting works well with gasoline, E85, ethanol blends, oil, coolant, and transmission fluid systems.

Especially important when your fuel pump sounds like it belongs on industrial construction equipment.

[Application] Widely utilized in automobile fuel systems, such as carburetors and injectors, in addition to fluid systems.

Clean Engine Bay Appearance

Beyond functionality, black anodized AN fittings help create a clean and organized engine bay appearance while resisting corrosion and wear over time. Pairing matching fittings throughout a build improves both serviceability and visual consistency.

Because if you’re going to spend 14 hours routing lines, they should at least look good afterward.
