EVIL ENERGY 6AN PTFE Straight Hose End Fittings — Black 4-Pack, 6061-T6 Aluminium, 1500 PSI

These straight 6AN fittings from EVIL ENERGY are engineered to mate only with PTFE-lined hose systems, offering a corrosion-resistant aluminum body and a sealed AN cone for reliable connections. Built from 6061-T6 aluminum, each fitting swivels freely to simplify routing and installation while standing up to a wide temperature range. The kit contains four identical fittings so you can equip multiple lines or keep spares on hand for maintenance.

How does this fitting attach to PTFE hose and stay leak-resistant?

The fitting uses an AN-style 37° cone to form the primary metal-to-metal seal common in performance fuel systems. The design requires PTFE-lined hose only; the smooth PTFE inner liner couples with the fitting’s insert so the seal is secure without compressing braided outer layers. The swivel nut lets you tighten the connection while orienting the hose for best routing.

• 37° AN sealing angle for standardized, reliable sealing
• Swivel nut allows final orientation after hand-tightening
• Intended exclusively for PTFE-lined hoses to ensure proper seal

What strength and temperature limits should I expect?

These EVIL ENERGY fittings are rated to handle up to 1500 PSI working pressure, making them suitable for many fuel and fluid systems where higher pressures occur. Temperature capability spans from -65°F to 252°F, covering typical operating ranges for automotive and racing environments. Keep in mind that overall system limits will also depend on your hose and fluid compatibility.

• Working pressure: 1500 PSI
• Temperature range: -65°F to 252°F
• Material strength from 6061-T6 aluminum construction

Will these fittings fit my AN specification system and how is size defined?

Yes — these are 6AN fittings, with a threaded size of 9/16-18 UNF, matching standard 6AN threaded ports and adapters. AN sizing denotes the hose and fitting diameter used in aviation and high-performance systems; confirm your hose is PTFE-lined and sized for 6AN to ensure proper fit. If you use adapters or different AN sizes, verify thread compatibility before assembly.

• AN size: 6AN (threaded 9/16-18 UNF)
• Designed to match standard AN thread and cone dimensions
• Confirm PTFE-lined hose with 6AN inner diameter for correct pairing

Who is this for: This 4-pack of EVIL ENERGY straight 6AN PTFE hose end fittings is aimed at automotive enthusiasts, race teams, fabricators, and technicians who work with PTFE-lined fuel or fluid hoses. It suits anyone needing durable, lightweight fittings that swivel for easier installation and provide a standardized AN seal. Avoid using these with non-PTFE hose types; they are purpose-built for PTFE-lined systems where a metal-to-metal 37° AN seal is required. The pack size makes it convenient for small projects, repairs, or stocking spare fittings for service work.
