EVIL ENERGY 12AN PTFE Hose End Fitting 45 Degree Black - Durable Fuel

In this review of the EVIL ENERGY 12AN PTFE Hose End Fitting 45 Degree Black, the bottom line is straightforward: this pair of fittings is aimed at anyone using PTFE fuel line who needs a compact, reliable 45 degree AN connection that resists leaks under high pressure. The reviewer found the fittings well suited to high-pressure PTFE hose assemblies because they combine a 37 degree AN seal with a sturdy 6061-T6 aluminum body and a 360 swivel design for easier alignment during installation.

Key Features

• Thread Size: The 12AN thread size (11/16-12 UNF) gives a standard, tight connection for common AN plumbing setups and reduces adapter guessing.
• PTFE Only Application: These hose ends are designed specifically for PTFE fuel line, ensuring material compatibility and a proper fit when used as intended.
• High Working Pressure: Rated for 1500 PSI, the fittings are suitable for many high-pressure fuel system or fluid transfer applications where PTFE hose is used.
• Temperature Range: With a -65F to 252F temperature tolerance, the fittings handle a wide span of operating environments from cold starts to hot engine bays.
• Sealing Design: The AN side uses a 37 degree angle seal that provides a reliable metal-to-metal seal when mated with the correct AN counterpart.
• Construction and Assembly: Machined from aluminum alloy 6061-T6 and featuring a 360 swivel, these hose ends are durable and simplify installation and routing.

Who It's For

This product is best for DIY mechanics, racers, and tuners who specifically use PTFE fuel line and need a robust AN-style 45 degree fitting. It is a practical choice when replacing worn hose ends or building a custom PTFE hose assembly where high pressure and temperature resistance matter.

It is not appropriate for non-PTFE hoses or applications requiring fittings with integrated barb ends for rubber hose, so those using other hose materials should look for a different style. Also, buyers who need a wide assortment of sizes or different angles will want to source additional fittings beyond this 2PCS pack.

Pros & Cons

Pros

• Good build quality from 6061-T6 aluminum provides durability for repeated use and uninstalling.
• Works well with PTFE hose and customers report no leakage when properly installed.
• 1500 PSI working pressure and wide temperature range suit demanding fuel system tasks.
• 360 swivel design makes alignment and tightening easier in tight spaces.

Cons

• Only compatible with PTFE hose, so it is not a universal hose end for other materials.
• Sold as a 2PCS pack which may not cover projects needing multiple fittings of other sizes or angles.

Frequently Asked Questions

Will these fittings work with rubber or braided nylon hose?
They are designed for PTFE fuel line only and are not suitable for rubber or standard braided hose without proper adapters.

What does the 37 degree seal mean?
The 37 degree angle refers to the AN-style metal-to-metal sealing surface used on the AN side to form a leak-resistant joint when properly tightened.

Are these fittings reusable?
Yes, the aluminum 6061-T6 construction and 360 swivel allow repeated installation and removal, though standard good practice is to inspect seals and hoses each time.
