EVIL ENERGY 10AN PTFE Hose End Fitting Straight Black — 4PCS, 6061-T6 Aluminum, 360° Swivel, 1500 PSI

EVIL ENERGY 10AN straight PTFE hose end fittings are black anodized aluminum connectors designed specifically to attach PTFE fuel lines securely, sold as a set of four.

These straight hose ends are purpose-built for PTFE-lined hoses and deliver a compact, high-pressure connection for fuel and fluid routing where chemical resistance and temperature tolerance matter. Machined from 6061-T6 aluminum and finished in black, each fitting features a 37° AN sealing face, a 7/8-14UNF thread size (10AN standard), and a 360° swivel to simplify installation in tight or rotating assemblies.

What makes these fittings compatible only with PTFE hose?

EVIL ENERGY designed the ferrule, sealing geometry, and inner seat to match PTFE-lined tubing characteristics — softer liners and specific outer diameters. Using these fittings on standard rubber hose or incompatible liners can compromise the seal or damage the hose.

• Sealing face angled 37° to match AN-style PTFE hose ends.
• Internal profile sized for PTFE liner wall thickness and diameter.
• Not recommended for rubber or braided non-PTFE hoses.

Can these fittings handle high pressure and wide temperature ranges?

Yes — the fittings are rated for working pressures up to 1500 PSI and operate across a broad temperature span, accommodating common automotive and industrial environments. The 6061-T6 aluminum body provides a solid strength-to-weight ratio while the PTFE-compatible interface preserves chemical and heat resistance.

• Working pressure: up to 1500 PSI under correct hose and assembly conditions.
• Temperature range: roughly -65°F to 252°F (-54°C to 122°C).
• Appropriate for many fuel, oil, and fluid systems when used as specified.

How does the 360° swivel help during installation?

The swivel nut allows the hose assembly to rotate independently of the fitting body, which minimizes hose twist and simplifies alignment when tightening. This feature is especially useful in cramped engine bays or when routing hoses around obstructions.

• Enables easier hand-tightening without twisting the hose lining.
• Reduces stress on hose ends during final orientation.
• Saves time when fitting multiple lines in confined spaces.

What are the key dimensions and mechanical details I should verify before ordering?

Confirm you need a 10AN size, which corresponds to the thread spec 7/8-14UNF; mismatched thread or AN size will prevent proper assembly. Also ensure your PTFE hose outer diameter and liner thickness match the fitting's internal profile for a reliable seal at rated pressures.

• Thread: 7/8-14UNF (10AN standard).
• Sealing: 37° AN-style sealing surface on the AN side.
• Material: machined 6061-T6 aluminum with black finish for corrosion resistance.

Who is this for: These EVIL ENERGY straight hose end fittings are aimed at mechanics, fabricators, racers, and DIY vehicle builders who use PTFE-lined fuel or fluid hoses and need compact, pressure-capable connections. If you run PTFE fuel lines, require a robust 10AN union with a 37° seal and value a rotating nut to ease final positioning, this four-piece black set is tailored to that workflow. They are not intended for non-PTFE hoses or applications exceeding the specified pressure and temperature ratings.
