EVIL ENERGY 8AN PTFE Straight Hose End Fittings — Black 4‑Pack, 360° Swivel, 1500 PSI

EVIL ENERGY 8AN straight hose end fittings are aluminum swivel connectors engineered specifically to join PTFE fuel hose, sold as a set of four for dependable, high-pressure applications.

This 4-piece kit contains 8AN (3/4-16UNF) straight hose end fittings designed exclusively for PTFE-lined fuel hose. Each fitting uses a 37-degree AN sealing angle, a 360° swivel nut for easier routing and assembly, and is machined from aircraft-grade 6061-T6 aluminum for a strong yet lightweight connection. Rated to 1500 PSI and tested across a wide temperature window, these fittings simplify installations where a PTFE inner liner is required.

Will these fittings work with my PTFE fuel line?

Yes — these fittings are intended only for PTFE-lined hoses and are not compatible with other soft rubber or braided hose types. The design clamps onto the PTFE liner to create a secure, pressure-rated joint when assembled correctly.

• Thread size: 8AN / 3/4-16UNF for standard AN hoses
• Sealing: 37° AN flare angle for metal-to-metal seal
• Swivel nut: 360° rotation for easier hose positioning
• Compatibility: PTFE-lined fuel hoses only

How durable and heat-resistant are these fittings?

The fittings are CNC-machined from 6061-T6 aluminum, giving a high strength-to-weight ratio and corrosion resistance suitable for automotive and motorsport environments. They maintain structural integrity across extreme temperatures and common operating pressures for fuel systems.

• Working pressure: up to 1500 PSI under proper assembly
• Temperature range: -65°F to 252°F (-54°C to 125°C)
• Material: aircraft-grade 6061-T6 aluminum for longevity
• Finish: black anodized or coated surface for wear resistance

How does the swivel design help during installation?

The 360° swivel nut lets you orient the hose without twisting the entire assembly, simplifying tight-routing and reducing stress on the PTFE liner. This feature is particularly useful in confined engine bays or custom plumbing runs.

• Allows final hose alignment after threading fittings into place
• Reduces torque transmission to the hose during tightening
• Saves time and minimises rework in complex installations
• Improves longevity by preventing hose kinks or bends at the junction

What size and sealing method should I expect?

These fittings use an 8AN thread (3/4-16UNF) and seal with a 37-degree AN flare, the industry standard for many fuel and fluid systems. Proper assembly and matching PTFE hose end prep are essential to reach the rated pressure and leak-free performance.

• AN size: 8AN (3/4-16UNF) — verify your hose end sizes first
• Seal: 37° angle provides metal-to-metal flare contact
• Assembly: requires correct TORCing and PTFE liner seating
• Pack: sold as a set of 4 identical straight fittings

Who is this for? These EVIL ENERGY 8AN straight PTFE hose end fittings are aimed at DIY mechanics, race shops, and custom builders who use PTFE-lined fuel hose and need a compact, high-pressure, and easy-to-route connection. If you work with fuel systems, turbo plumbing, or any application requiring PTFE hoses and AN fittings, this four-pack offers a practical, durable option for reliable fluid connections.
