EVIL ENERGY 6AN PTFE Hose End Fitting Straight Black — 2PCS, 37° AN Seal & 360° Swivel, 6061-T6 Aluminum

EVIL ENERGY 6AN straight hose end fittings are black aluminum swivel adapters designed specifically to connect PTFE fuel hose securely and withstand high pressure in automotive and racing applications.

These two-pack 6AN fittings are purpose-built for PTFE (Teflon-lined) fuel lines. Machined from 6061-T6 aluminum with a 37° AN sealing angle and a full 360° swivel, they deliver a leak-resistant connection while allowing easier routing and assembly in tight engine bays. Rated to 1500 PSI and usable from -65°F to 252°F, they suit high-performance fuel systems and installations that demand durable, lightweight fittings.

How do these fittings ensure a reliable seal on PTFE hose?

The fittings use the AN standard 37° sealing surface on the threaded side to compress against the hard PTFE hose end, forming a metal-to-metal seat that prevents leaks when torqued correctly. These fittings are only intended for PTFE-lined fuel hose, so pairing with the correct hose material is essential for the intended seal performance.

• 37° AN sealing angle for proven metal-to-metal seating
• Thread size: 6AN (9/16-18 UNF) for standard AN connections
• Compatible only with PTFE (Teflon-lined) fuel hose to maintain seal integrity
• Sold as a pair for dual-line or spare use

What temperatures and pressures can these 6AN fittings handle?

Designed for demanding automotive and racing environments, the fittings support a broad temperature range and high working pressure so they remain functional under engine heat and system load. Always verify system limits and install according to manufacturer torque specifications.

• Working pressure: rated to 1500 PSI for high-pressure fuel systems
• Temperature range: -65°F to 252°F (suitable for most engine compartments)
• Corrosion-resistant 6061-T6 aluminum construction helps maintain strength over temperature cycles

How does the 360° swivel design help during installation?

The swivel allows the hose to rotate independently of the threaded connection, making it easier to align and tighten fittings in cramped spaces without twisting the hose. This reduces installation time and stress on the hose assembly while providing a neat routing path.

• Full 360° swivel for flexible orientation during assembly
• Prevents hose twisting and helps achieve cleaner hose runs
• Speeds up installation in tight engine bay locations

What materials and sizes should I expect from this EVIL ENERGY fitting?

The fitting is machined from aircraft-grade 6061-T6 aluminum and finished in a durable black coating for corrosion resistance and a race-ready look. The thread specification adheres to 6AN standards so it mates with existing AN hardware without adapters.

• Material: aluminum alloy 6061-T6 for strength and light weight
• Thread size: 6AN (9/16-18 UNF) standard AN thread
• Finish: black coating for corrosion protection and aesthetics
• Package: two fittings per order (2PCS)

Who is this for: These EVIL ENERGY 6AN straight PTFE hose end fittings are intended for mechanics, fabricators, and motorsport enthusiasts installing or repairing PTFE-lined fuel systems. They are ideal if you need high-pressure, temperature-capable AN connections with a swivel feature for easier routing and assembly. Do not use them with non-PTFE hoses—pair them only with compatible PTFE fuel lines for safe, leak-free performance.
