EVIL ENERGY 4AN Straight Hose End Fittings 2pc — 7/16-20 UNF Thread, 6061-T6 Aluminium, 360° Swivel

EVIL ENERGY 2PCS 4AN straight hose end fittings are 6061-T6 aluminum, swivel-ready connectors designed for stainless-steel and nylon braided fuel hoses.

These 4AN straight fittings combine lightweight, corrosion-resistant aluminum with a 37° AN sealing angle and a full 360° swivel to simplify fuel-line assembly and maintenance. Built for pressure systems in automotive and motorsport applications, the fittings are rated to 1,500 PSI and operate across a wide temperature span, making them suitable for many engine bay and fluid-transfer setups.

Will these fittings fit my existing braided fuel hose?

The fittings are made specifically to mate with stainless-steel and nylon braided CPE-style hoses that accept AN-style hose ends. The threaded side uses a 7/16-20 UNF size, and the AN side seals on a 37° flare angle commonly used in performance plumbing.

• Thread size: 7/16-20 UNF on the threaded end.
• AN sealing: 37° male AN seating angle for leak-tight joins.
• Compatible hose types: stainless-steel braided and nylon braided CPE hoses.

How durable and heat-resistant are these EVIL ENERGY fittings?

Manufactured from 6061-T6 aluminum, the fittings offer a high strength-to-weight ratio and good resistance to corrosion and vibration. Their rated working temperature range supports typical automotive environments without material deformation or loss of seal integrity under normal operating conditions.

• Material: 6061-T6 aluminum alloy for strength and lightweight performance.
• Temperature range: -40°F to 248°F (-40°C to 120°C).
• Pressure rating: up to 1,500 PSI for typical fuel and fluid systems.

How does the 360° swivel improve installation and maintenance?

The swivel design allows the hose to rotate independently from the threaded or AN connection, reducing hose twist and simplifying alignment when routing lines around tight engine-bay obstacles. This makes assembly faster and helps prevent stress on hose crimps and fittings during vibration or movement.

• 360° swivel lets you position hoses without twisting them.
• Reduces strain on hose ends for longer component life.
• Reusable and recyclable construction for multiple assemblies.

What should I know before reusing these fittings?

These fittings are designed to be reusable when inspected and reinstalled correctly; however, always check sealing surfaces and threads for wear, debris, or damage before reuse. Use proper torque and thread engagement to maintain a reliable seal and avoid cross-threading on the UNF side.

• Inspect 37° sealing surfaces for nicks or dents before reuse.
• Confirm thread condition on the 7/16-20 UNF side to prevent leaks.
• Follow manufacturer torque specs for secure, repeatable joints.

Who is this for: These EVIL ENERGY 4AN straight hose end fittings are aimed at DIY mechanics, race teams, and anyone upgrading or repairing braided fuel and fluid lines. They suit builders who need lightweight, corrosion-resistant connectors with a convenient swivel action for tight routing situations, and they work well in performance, custom, and maintenance applications where a dependable AN-style connection is required.
