EVIL ENERGY 10AN PTFE Straight Hose End Fittings, Black Aluminum 2-Pack — 360° Swivel, 6061‑T6

EVIL ENERGY 10AN straight PTFE hose end fittings are black aluminum 2-piece connectors designed specifically to attach PTFE fuel hose securely and swivel for easy installation.

These straight hose end fittings are purpose-built for PTFE-lined fuel lines and are supplied as a pair. Machined from 6061-T6 aluminum and finished in a hard black coating, they combine corrosion resistance with a 360° swivel design so you can assemble tight routings without twisting the hose. The AN side seals on a standard 37° angle and threads into a 7/8-14UNF (10AN) port, making them compatible with many aftermarket fuel and oil systems that specify AN fittings.

What makes these fittings suited to PTFE fuel hose?

EVIL ENERGY fittings are engineered specifically to mate with PTFE-lined hose, not conventional rubber lines. The internal geometry and sealing angle match AN standards and the components clamp onto the PTFE liner without deforming it. That ensures a reliable mechanical connection while preserving the PTFE inner surface.

• Designed only for PTFE fuel hose to preserve liner integrity.
• 37° AN sealing face provides a metal-to-metal seal.
• 360° swivel avoids hose twisting during installation.
• Hard black finish for corrosion resistance and cleaner appearance.

How durable are these fittings under pressure and temperature?

These 10AN fittings are rated for high-pressure use and a broad temperature range suitable for automotive and motorsport applications. The aluminum 6061-T6 construction delivers strength and light weight, while the specified working pressure and temperature limits reflect common operating conditions for fuel systems.

• Working pressure: 1500 PSI for reliable sealing in fuel applications.
• Temperature range: -65°F to 252°F to suit cold starts and hot engine bays.
• 6061-T6 aluminum resists fatigue and reduces weight compared with steel.
• Black surface treatment adds corrosion protection and visual uniformity.

How do I install these 10AN straight hose ends on PTFE hose?

Installation is straightforward if you follow the steps for AN-style hose ends and PTFE hose. Cut the hose square, insert the fitting components per the hose manufacturer’s instructions, and tighten to the recommended torque. The swivel collar helps you orient the hose without transmitting torsion to the line.

• Cut PTFE hose squarely and deburr before assembly.
• Insert the fitting and seat the PTFE liner into the socket fully.
• Tighten the nut until the AN 37° seat engages; use recommended torque values.
• Use the 360° swivel to align hose routing without twisting the hose.

Which vehicles or systems commonly use a 10AN PTFE fitting?

10AN (7/8-14UNF) fittings are common in aftermarket fuel, oil, and coolant systems where PTFE-lined hose is required for chemical resistance or temperature tolerance. They are popular in performance cars, racing builds, and custom fabrications that demand reliable, leak-free connections under high pressure.

• Aftermarket fuel rails, surge tanks, and carburetor feeds on performance vehicles.
• Oil cooler lines and remote oil filter setups using PTFE hose.
• Custom plumbing in motorsport and engine swaps requiring high-pressure fittings.
• Applications where PTFE lining prevents fuel permeation and chemical attack.

Who is this for: This pair of EVIL ENERGY 10AN straight PTFE hose end fittings is for vehicle builders, tuners, and technicians who use PTFE-lined hose and need a durable, high-pressure AN connection with a 360° swivel for easy routing. Choose these if you require a 7/8-14UNF (10AN) straight fitting with a 37° sealing face, wide temperature tolerance, and the lightweight strength of 6061-T6 aluminum.
