EVIL ENERGY AN6 Tee Adapter — 6AN Male with AN6 Female Swivel, Black 6061-T6 Aluminum, 1500 PSI

EVIL ENERGY's 6AN male tee adapter with a side AN6 female swivel provides a compact, high-pressure branching point for fluid systems where a swiveling side connection is needed.

This aluminum AN6 tee fitting is engineered for automotive and motorsport fluid plumbing where strength, leak resistance, and flexibility matter. Machined from 6061-T6 billet aluminum, the TEe uses a 37° AN flare sealing surface and supports up to 1500 PSI. It handles fuel, oil, E85, coolant and compressed air across a wide temperature range, making it a versatile component when routing lines in tight engine bays or custom plumbing projects.

How does this AN6 tee adapter perform under pressure and temperature extremes?

The adapter is rated for a working pressure of 1500 PSI and is tested to tolerate temperatures from -40°F to 250°F, so it performs reliably across typical automotive operating conditions. Its 37° AN flare sealing geometry ensures a metal-to-metal seat that resists leaks under vibration and thermal cycling.

• Working pressure: 1500 PSI for high-demand systems
• Temperature tolerance: -40°F to 250°F for broad environmental use
• 37° AN flare seal minimizes leak risk in dynamic applications

What materials and construction features make it durable?

The tee is CNC-machined from 6061-T6 aluminum, a common aerospace-grade alloy that balances light weight with excellent strength and corrosion resistance when anodized. The swivel female side port allows routing flexibility without twisting hoses, reducing stress and wear at fittings.

• Material: 6061-T6 aluminum for strength and low weight
• Swivel AN6 female side port for easier hose alignment
• Black finish provides added surface protection and a clean appearance

Which fluids and systems can this 6AN tee be used with?

Designed for multi-fluid compatibility, the tee accepts oil, gasoline, E85 blends, coolant, hydraulic fluids and air, making it suitable for fuel systems, oil feed/return lines, coolant bypasses and pneumatic setups. Always pair with compatible hoses and clamps rated for the specific fluid and temperature.

• Compatible with fuel, oil, E85, coolant, and compressed air
• Ideal for fuel rails, turbo oil feeds, coolant reroutes, and air lines
• Use with AN6 hoses and properly rated clamps or crimp fittings

How do I size and install the AN6 tee correctly?

The 6AN designation corresponds to a 9/16-18 UNF thread and the AN flare standard; confirm your hoses and ports are AN6 to ensure fit. During installation, hand-start threads to avoid cross-threading, tighten to proper torque for AN fittings, and inspect the 37° flare seating surface for clean, undamaged contact surfaces.

• Thread size: 9/16-18 UNF (AN6 standard)
• Installation tip: hand-start threads, then torque to recommended AN values
• Inspect flare surfaces and use compatible hose ends or adapters

Who is this for: Builders, tuners and fabricators who need a compact, robust plumbing branch in performance vehicles will value this EVIL ENERGY AN6 tee. It’s aimed at people installing or modifying fuel, oil and coolant systems who require a swivel side connection for clean hose routing in tight spaces. If you prefer durable, machined fittings with proven flare sealing and broad fluid compatibility, this fitting matches those needs.
