EVIL ENERGY 6AN PTFE Straight Hose End Fitting — Black Hard‑Anodized, 2‑Piece Swivel 1500 PSI

EVIL ENERGY 6AN straight PTFE hose end fitting (2 pieces) is a durable, swivel 6AN aluminum connector made exclusively for PTFE fuel hose that seals with a 37° AN seat and holds up to 1500 PSI.

This pair of straight 6AN hose end fittings is built for PTFE-lined fuel hose assemblies where reliable sealing, high pressure tolerance and easy installation matter. Machined from 6061‑T6 aluminum and engineered with a 360° swivel, these fittings let you route PTFE fuel lines precisely without twisting the hose. The fittings accept a 9/16-18 UNF thread and operate across a broad temperature range from -65°F to 252°F, making them suitable for many automotive and performance applications.

Will these fittings work with my existing PTFE fuel line?

Yes — these hose ends are designed specifically for PTFE-lined fuel hose and will not function correctly with other hose types. They use a 37° AN seat to form the primary seal and rely on proper assembly for leak-free operation.

• Compatible only with PTFE-lined fuel hose
• Thread size: 6AN (9/16-18 UNF)
• Seals on a 37° AN angle for standard AN connections
• Sold as a 2-piece straight fitting set

How durable and heat-resistant are these 6AN fittings?

Machined from aircraft-grade 6061‑T6 aluminum, the fittings balance strength and light weight while resisting corrosion in fuel system environments. They are specified for working pressures up to 1500 PSI and handle temperatures from -65°F to 252°F, covering common under‑hood and motorsport conditions.

• Material: 6061‑T6 aluminum for strength and corrosion resistance
• Working pressure: rated to 1500 PSI
• Temperature range: -65°F to 252°F for broad application use
• Hard‑anodized black finish for added surface protection

How does the 360° swivel feature help during installation?

The rotating collar allows the hose to be positioned accurately after the fitting is tightened, preventing hose twist and reducing stress on the PTFE liner. That makes routing simpler in tight engine bays and improves longevity by avoiding kinks or strain.

• 360° swivel collar for final orientation without twisting hose
• Simplifies tight‑space routing and alignment
• Helps reduce liner stress and potential fatigue points
• Speeds up assembly and maintenance tasks

What are the key installation points I should follow?

Proper assembly is critical—these fittings depend on correct hose preparation and torque values to seal on the 37° AN seat. Use the recommended cutting, flaring or hose end installation procedure for your PTFE hose and tighten to the appropriate torque for 6AN fittings.

• Prepare PTFE hose ends cleanly per hose manufacturer instructions
• Hand‑start threads, then torque to recommended AN spec (avoid over‑tightening)
• Verify swivel orientation before final torque
• Pressure‑test the assembly before regular operation

Who is this for? These EVIL ENERGY 6AN straight PTFE hose end fittings are aimed at DIY mechanics, tuners and race teams who use PTFE‑lined fuel hose and need reliable, high‑pressure AN connections with easy routing. If you require a lightweight, corrosion‑resistant fitting that seals on a standard 37° AN seat and allows final orientation via a swivel collar, this 2‑piece set is a practical choice for street performance, track or custom plumbing projects.
