EVIL ENERGY 10AN Straight Push-Lock Hose Fittings 2pcs — 5/8" Barb Black, 6061-T6 Aluminum, 1500 PSI

EVIL ENERGY 10AN Straight Push Lock Hose Fitting End (2pcs) is a black 10AN-to-5/8" barb straight fitting made from 6061-T6 aluminum for secure connections to rubber fuel lines.

This pair of straight push-lock hose fitting ends is designed for performance fuel and fluid routing where a solid, compact connection is required. Each fitting converts a 10AN threaded port (7/8-14 UNF) to a 5/8" barb intended for rubber hose, offering a lightweight aluminum construction rated for demanding temperatures and pressures commonly encountered in automotive and motorsport plumbing.

How does this fitting connect to my fuel line?

The fitting uses a 5/8" barbed end to accept rubber fuel hose and a 10AN threaded end (7/8-14 UNF) for the receiving port. Push the rubber hose onto the barb until fully seated and secure it with an appropriate clamp to maintain a reliable seal under pressure.

• Barb size: 5/8" for standard rubber fuel hose
• Thread: 10AN (7/8-14 UNF) for AN-style ports
• Installation tip: use quality clamps for best sealing

What pressure and temperature can these fittings handle?

Each fitting is rated for a maximum working pressure of 1,500 PSI and a temperature range from -40°F to 248°F. That range suits most fuel, oil, and coolant routing scenarios in automotive and light motorsport environments when used with compatible rubber hose and proper clamps.

• Max working pressure: 1,500 PSI
• Temperature range: -40°F to 248°F
• Use only with specified hose types to preserve rating

What material is used and why does it matter?

The fittings are machined from 6061-T6 aluminum, a corrosion-resistant alloy valued for its strength-to-weight ratio. That makes the fittings lightweight while maintaining structural integrity for repeated installations and high-vibration use.

• Material: 6061-T6 aluminum alloy
• Finish: black coating for visual conformity and basic corrosion protection
• Durability: suitable for automotive environments when installed correctly

Which hose and applications are appropriate for these fittings?

These barb fittings are intended exclusively for rubber fuel lines; they are not compatible with hard tubing or braided AN hose without adapters. Common uses include replacement or custom fuel, oil return, and vent plumbing where a barb-to-AN threaded transition is needed.

• Compatible hose: rubber fuel lines only
• Common uses: fuel systems, return lines, venting applications
• Not for direct use with rigid metal tubing or push-on synthetic braided hose

Who is this for? If you build, repair, or modify automotive fuel systems and need a compact 10AN-to-5/8" barb conversion with a lightweight aluminum body, these EVIL ENERGY fittings are a practical choice. They suit mechanics, home-garage fabricators, and motorsport technicians who use rubber fuel hoses and want a durable, easy-to-install connector. Remember to pair the fittings with the correct hose, clamps, and torque on the 10AN thread, and inspect connections regularly for leaks or wear.
