EVIL ENERGY 6AN Straight Push-Lock Hose Fitting End — Black, 2-Pack, 3/8" Barb, 6061-T6 Aluminum

This pair of straight push-lock fittings from EVIL ENERGY delivers a compact, corrosion-resistant transition between AN-style plumbing and push-on rubber fuel hose. Machined from 6061-T6 aluminum and finished in black, each fitting uses a 9/16-18 UNF 6AN threaded end and a 3/8" barb to attach soft fuel lines securely. Designed for workshop and motorsport use, they balance lightweight construction with practical sealing performance when paired with hose clamps.

How does this fitting connect an AN line to a rubber fuel hose?

Each fitting features a 6AN male threaded end that mates with standard 9/16-18 UNF female AN ports and a tapered 3/8" barb to accept push-on rubber hose. The barbed section grips the hose internally while the AN thread provides a reliable mechanical interface to braided lines or adapters.

• 6AN end thread: 9/16-18 UNF for standard AN ports
• Barb size: 3/8" for compatible rubber fuel hose
• Installation: push hose over barb, secure with clamp for best sealing
• Sold as a set of 2 identical straight fittings

What materials and durability can I expect from these connectors?

The fittings are machined from aircraft-grade 6061-T6 aluminum for a high strength-to-weight ratio and finished in a black coating to resist wear and corrosion. They are rated for typical fuel system pressures and a wide temperature range suitable for most automotive environments.

• Material: 6061-T6 aluminum alloy for light strength
• Working pressure: up to 1,500 PSI in ideal conditions
• Operating temperature: -40°F to 248°F for broad climate use
• Finish: black surface treatment for corrosion protection

Are these fittings easy to install and maintain?

Yes — these straight push-lock fittings are designed for straightforward installation. Slide the rubber hose over the 3/8" barb and tighten a hose clamp or crimp clamp to improve sealing; thread the 6AN end into the mating port using proper tightening practices to avoid cross-threading.

• Quick to install: push hose onto barb, secure with clamp
• Recommended: use hose clamps to ensure leak-free operation
• Maintenance: inspect clamps and hose periodically for wear
• Do not use with hard or non-rubber tubing

Who is this for? These EVIL ENERGY 6AN straight push-lock fittings suit mechanics, fabricators, and motorsport enthusiasts who need a compact, reliable transition from AN-threaded hardware to soft rubber fuel lines. If you work on carbureted setups, fuel pumps, or custom plumbing where lightweight aluminum fittings and a narrow temperature range are acceptable, this 2-piece set offers an affordable and easy-to-install solution. Avoid using them with non-rubber tubing and always pair with clamps for best sealing performance.
