EVIL ENERGY 8AN PTFE Straight Hose End Fittings, Black 2-Pack — 360° Swivel & 37° AN Seal

EVIL ENERGY 8AN PTFE straight hose end fitting (black) is a two-piece aluminum 8AN connector designed specifically for PTFE fuel hose, offering a 360° swivel, 37° AN seal, and up to 1500 PSI working pressure.

This pair of straight hose end fittings is engineered to join PTFE-lined fuel lines to standard AN-threaded components without compromising the hose’s inner PTFE liner. Machined from 6061-T6 aluminum and finished in a durable black coating, the fittings deliver corrosion resistance and light weight for high-performance automotive and industrial applications. They are precision-threaded 3/4-16UNF (8AN) and optimized for PTFE hose compatibility only; they are not intended for braided or rubber hose types.

How do these fittings connect to PTFE hoses reliably?

The fittings use a design that compresses the hose outer assembly while leaving the PTFE liner intact, preserving chemical resistance and flow characteristics. A 37° AN sealing angle on the AN side ensures a metal-to-metal seat that creates a leak-resistant joint when torqued to specification.

• Thread size: 8AN (3/4-16UNF) for common AN ports.
• AN side uses a 37° sealing angle for dependable seats.
• 360° swivel allows alignment without twisting the hose.
• Designed specifically for PTFE-lined hose—do not use with non-PTFE hose.

What pressure and temperature conditions are supported?

These fittings are rated for a working pressure up to 1500 PSI, suitable for many fuel, oil, and fluid delivery systems in performance and industrial settings. The operating temperature range spans from -65°F to 252°F, accommodating cold starts and elevated under-hood temperatures typical in motorsports and heavy equipment.

• Working pressure: 1500 PSI.
• Temperature range: -65°F to 252°F.
• Material stability from wide operating temperatures thanks to 6061-T6 alloy construction.

What materials and mechanical features improve ease of use?

Manufactured from aircraft-grade 6061-T6 aluminum, these hose ends balance strength and lightweight performance. The 360° swivel feature reduces installation stress by allowing you to orient the hose end after thread engagement, which simplifies routing in tight spaces and prevents hose twisting.

• 6061-T6 aluminum body for corrosion resistance and reduced weight.
• Black anodized finish improves durability and visual matching to systems.
• Swivel coupling allows final positioning without rotating the hose.

Are these fittings compatible with my system and how should I install them?

These fittings are intended exclusively for PTFE-lined hoses and standard AN-threaded ports sized 8AN (3/4-16UNF). Installation requires correct hose prep—cut square, seat the liner, and follow torque recommendations for AN fittings. Avoid using with braided or rubber hoses; mismatch can cause leaks or damage.

• Use only with PTFE-lined fuel lines sized for 8AN connections.
• Prepare the hose liner and clamp according to PTFE hose fitting best practices.
• Hand-start threads, then torque to AN spec; use swivel to align hose without twisting.

Who is this for: These EVIL ENERGY straight 8AN PTFE hose end fittings are aimed at automotive enthusiasts, race technicians, custom fabricators, and industrial mechanics who need reliable, lightweight connectors for PTFE-lined fuel or fluid lines. If you require a high-pressure compatible, corrosion-resistant AN connection with easy routing and precise sealing for PTFE hoses, this two-piece set is a practical choice. Do not purchase if you need fittings for rubber or braided non-PTFE hoses, or for thread sizes other than 8AN (3/4-16UNF).
