EVIL ENERGY 6AN Straight Push-Lock Hose Fitting, 2pcs Black Anodized Aluminium — 3/8" Barb, 1500 PSI

EVIL ENERGY 6AN straight push-lock hose fittings are black anodized 6061-T6 aluminum 2-piece connectors that convert a 6AN threaded port to a 3/8" rubber fuel line barb for reliable, lightweight fluid routing.

These push-lock hose fittings are designed for fuel and other low-compression fluid lines where a secure, compact transition from an AN-threaded port to a rubber hose is required. Machined from 6061-T6 aluminum and finished in black anodize, the fittings offer corrosion resistance and a professional appearance. The 6AN female thread measures 9/16-18 UNF and mates to standardized AN ports; the 3/8" barb accepts rubber fuel hose and is best used with a clamp for optimal sealing. Rated for up to 1,500 PSI and a wide temperature range, these fittings suit many automotive and motorsport plumbing applications.

How do these fittings attach to AN ports and rubber hose?

Each fitting screws into a 6AN (9/16-18 UNF) threaded port, creating a compact straight connection. The opposing end features a 3/8" barb sized for rubber fuel lines; push the hose onto the barb and secure it with a clamp to improve sealing and prevent leaks under pressure.

• 6AN thread: 9/16-18 UNF for standard AN compatibility
• Barb diameter: 3/8" to match common fuel hoses
• Clamps recommended for leak-proof installation
• Straight orientation for minimal flow disruption

What materials and pressure ratings should I expect?

These fittings are machined from 6061-T6 aluminum, a common choice for lightweight strength and corrosion resistance when anodized. They are rated for a maximum working pressure of 1,500 PSI and operate across a broad temperature span, making them suitable for many engine-bay and fuel-system uses (with proper hose and clamps).

• Body material: 6061-T6 aluminum with black finish
• Working pressure: up to 1,500 PSI
• Temperature range: -40°F to 248°F (-40°C to 120°C)
• Durable finish for corrosion and wear resistance

Are these fittings compatible with all hose types and fluids?

The barb is specifically intended for rubber fuel lines; it is not designed for hard tubing or PTFE hoses without a compatible adapter. Use these fittings only with hoses rated for the intended fluid and operating conditions, and confirm chemical compatibility for specialized fuels or additives.

• Recommended hose: rubber fuel line sized for 3/8" barb
• Not for rigid tubing unless adapted
• Check hose chemical compatibility for additives or specialty fuels
• Always secure with appropriate hose clamps

How easy is installation and maintenance?

Installation is straightforward: thread the 6AN end into the port, push the rubber hose onto the barb, and tighten a clamp. Regular inspection of hose clamps and the anodized finish is recommended to ensure long-term sealing and to spot any wear or corrosion early.

• Thread engagement: standard 6AN 9/16-18 UNF
• Push-on barb for quick hose connection
• Use clamps to boost sealing performance
• Inspect periodically for wear or loosening

Who is this for? These EVIL ENERGY 6AN straight push-lock barb fittings are intended for automotive and motorsport enthusiasts, tuners, and DIY mechanics who need a compact, lightweight adapter from an AN threaded port to a 3/8" rubber fuel line. If you work on carbureted or fuel-injected engines, small engines, or custom plumbing where rubber fuel hoses are used, this 2-piece set offers a durable, serviceable connector that balances strength, appearance, and ease of use. Not suitable as a substitute for rigid-line plumbing in high-temperature or chemically aggressive systems—verify hose and fluid compatibility before installation.
