EVIL ENERGY 8AN 45° PTFE Hose End Fittings — Black, 2‑Piece Set, 6061‑T6 Aluminum, 360° Swivel

EVIL ENERGY 8AN 45° PTFE hose end fittings are 45-degree, 8AN aluminum connectors designed specifically to join PTFE fuel hose—sold as a two-piece set.

This pair of 45° hose end fittings is built for use with PTFE-lined fuel hose, offering a compact angled connection that resists high pressure and wide temperature swings. Machined from 6061-T6 aluminum and fitted with a 37° AN sealing surface, these fittings provide a reliable mechanical joint for race, marine, and custom fuel systems where PTFE hose is specified. They are not universal hose fittings and will not properly seal on non-PTFE hose.

How do these 45° AN fittings perform under pressure?

These fittings are rated for high-pressure fuel applications and are machined to meet AN standards for sealing and thread engagement. The swivel design helps prevent twisting and eases installation under load.

• Working pressure: up to 1500 PSI
• AN sealing: 37° flare angle for metal-to-metal seal
• Thread: 8AN thread corresponds to 3/4-16 UNF
• Temperature tolerance: -65°F to 252°F for wide-range environments

Will these fittings work with all fuel hoses and fluids?

These hose ends are purpose-made for PTFE-lined hose and are not intended for conventional rubber or fabric fuel lines. PTFE hose provides chemical compatibility with many fuels and additives, but the fitting must be paired with PTFE hose to form a proper seal.

• Compatible only with PTFE-lined fuel hose
• Not recommended for non-PTFE hoses or crimp-type connections
• Suitable for many fuels and chemically compatible fluids when using PTFE hose

What materials and construction details matter for durability?

The connectors are CNC-machined from 6061-T6 aluminum for a strong, lightweight component that resists corrosion when anodized or properly finished. The 360° swivel feature reduces hose torque during assembly and service, extending hose life and simplifying fitting alignment.

• Material: aluminum alloy 6061-T6 for strength and weight savings
• 360° swivel: easier alignment and prevents hose twisting
• Seals on AN 37° flare: metal-to-metal contact for reliable sealing

How do I install these fittings and what should I check?

Installation requires the correct PTFE hose size and following manufacturer crimp or clamp instructions for PTFE systems. Tighten the fitting to the specified torque for 8AN (3/4-16UNF) threads and inspect the 37° sealing surface for proper contact.

• Confirm hose is PTFE-lined and the correct inner/outer diameter for 8AN
• Use proper crimping tools or approved hose ends per PTFE hose manufacturer
• Torque threads to recommended values and verify 37° seal engagement

Who is this for: These EVIL ENERGY 8AN 45° fittings are aimed at automotive, motorsport, marine, and custom-fabrication users who need a compact, high-pressure angled connection for PTFE-lined fuel hose. Choose this two-piece set if you require durable 6061-T6 construction, a 37° AN sealing interface, and a swivel design to simplify routing and installation in tight engine bays or fuel systems.
