EVIL ENERGY 6AN Female to 3/8" Barb Straight Swivel Adapter, 2PCS — 6061‑T6 Aluminium, 1500 PSI

High-strength aluminum swivel fittings that adapt a 6AN female flare connection to a 3/8" barb hose, sold as a pair and built for high-pressure fluid routing.

EVIL ENERGY's 6AN female to 3/8" barb straight swivel fittings are lightweight, corrosion-resistant adapters intended for custom fuel, oil, coolant, or vacuum lines where a secure AN flare connection must transition to hose. Machined from 6061-T6 aluminum and sealed by a 37° AN flare interface, these fittings combine workshop compatibility with service temperatures and pressures commonly encountered in automotive and racing applications.

How does this fitting ensure a leak-resistant connection?

The female AN side uses the standard 37° flare seating geometry to create a metal-to-metal seal against a mating male AN flare. The barb side accepts 3/8" (OD) hose and is designed for hose clamps to secure a tight mechanical bond. Together, they provide a reliable seal in both static and dynamic fluid systems when installed correctly.

• 37° flare on AN side for proven metal-to-metal sealing
• 3/8" barb OD sized for common fuel and coolant hoses
• Recommend using hose clamps to prevent slip and leaks

What materials and pressures can I expect from these adapters?

Each fitting is CNC-machined from 6061-T6 aluminum for an excellent strength-to-weight ratio and corrosion resistance. The working pressure rating is listed at 1500 PSI, with an operational temperature range from -65°F to 252°F, making them suitable for many automotive and industrial fluid applications.

• 6061-T6 aluminum alloy body for strength and low mass
• Working pressure: 1500 PSI (operational condition dependent)
• Temperature range: -65°F to 252°F

How do I install the 6AN female to 3/8" barb swivel fitting correctly?

Installation is straightforward: thread the 6AN female onto the corresponding male AN flare and tighten to the appropriate torque; then push the hose over the 3/8" barb and secure it with a clamp. The swivel design allows alignment without twisting the hose, making assembly easier in tight spaces.

• Hand-start the AN threads, then torque to recommended spec for AN fittings
• Push hose fully over the barb and fit a compatible hose clamp
• Use swivel feature to align hose without torsion on the line

Who is this product for? These 2PCS EVIL ENERGY adapters suit DIY mechanics, race teams, custom fabricators, and anyone building or repairing fluid lines that require an AN flare transition to common rubber or PTFE hose. They are ideal when you need a compact, lightweight, and serviceable connection with a standard 6AN interface and 3/8" hose compatibility. Always pair with compatible hoses, clamps, and properly matched AN fittings for safe, long-lasting service.
