EVIL ENERGY 6AN PTFE Straight Hose End Fitting — 4pc Black, 6061-T6 Aluminum, 360° Swivel for PTFE Fuel Hose

This set of four straight hose-end fittings from EVIL ENERGY is crafted for use with PTFE-lined fuel hose systems where a durable, high-pressure, corrosion-resistant connection is required. Machined from 6061-T6 aluminum and featuring a 360° swivel design and a 37° sealing angle on the AN side, each fitting accepts 6AN thread size (9/16-18 UNF) and is rated for demanding temperature and pressure ranges. They are designed exclusively for PTFE hose and include features intended to simplify assembly without sacrificing reliability.

How does this fitting perform under pressure and temperature extremes?

These fittings are built to handle high-pressure PTFE hose applications, with a working pressure rating suitable for many fuel and fluid systems. The aluminum alloy body and precision sealing help maintain integrity across a wide thermal window.

• Working pressure: 1500 PSI for robust system compatibility
• Temperature range: -65°F to 252°F for broad operating conditions
• 37° AN-side sealing angle for secure leak-resistant mating

Will these fittings fit my hose and how do they connect?

These fittings are specifically intended to be used with PTFE-lined hoses and will not properly seal with other hose types. They thread with standard 6AN dimensions and use the AN flare sealing geometry to form the fluid-tight joint.

• Thread size: 6AN (9/16-18 UNF) — matches common AN threaded ports
• Exclusive compatibility: intended for PTFE fuel hose only
• 360° swivel allows alignment during installation without twisting the hose

What materials and design features improve durability and installation?

Manufactured from 6061-T6 aluminum, these fittings balance strength and weight while resisting corrosion in typical automotive and motorsport environments. The swivel design reduces installation strain on hose assemblies and helps achieve a clean routing layout.

• Material: 6061-T6 aluminum for strength and lightness
• 360° swivel design to ease assembly and prevent hose torsion
• Precision-machined surfaces for consistent AN-angle sealing

Are there any practical tips for installation and maintenance?

Proper installation requires matching the fitting to PTFE hose ends and ensuring the 37° AN sealing surfaces are clean and undamaged. Use appropriate tools to tighten to recommended torque for AN fittings and inspect seals periodically for wear in high-vibration service.

• Clean mating surfaces and inspect the 37° flare before tightening
• Hand-start threads, then tighten with AN wrenches to avoid cross-threading
• Regularly check fittings in harsh or high-vibration environments

Who is this for? If you install, repair, or upgrade PTFE-lined fuel hose systems—whether for street vehicles, race cars, machinery, or custom builds—this EVIL ENERGY 4-pack of straight 6AN PTFE hose-end fittings is aimed at mechanics, fabricators, and DIY enthusiasts who require reliable AN-style connections with a swivel feature for straightforward routing and assembly. These fittings are not universal hose connectors; they are intended for PTFE hose applications where AN threads and a 37° sealing angle are part of the system design.
