EVIL ENERGY 12AN to 3/4 in Barb Push Lock Fitting - Full Flow

Our review looks at the EVIL ENERGY 12AN 150 Degree Push Lock Fitting and concludes it is a practical, heavy-duty option for anyone fitting or repairing rubber fuel lines where a compact, one-piece connection is needed. The single biggest reason to buy is the combination of a one-piece full flow design with 6061-T6 aluminum construction, which yields smooth flow and solid build quality for automotive fuel-system work while tolerating a wide temperature range.

Key Features

• Size: The 12AN to 3/4 in barb conversion fits common rubber fuel hose sizes while providing the specified 1 1/16-12 UNF thread for secure attachment.
• Material: Machined from aluminum alloy 6061-T6, it offers good strength and resistance to corrosion for under-hood applications.
• Pressure rating: With a max working pressure of 1500 PSI, it is suitable for many fuel system and low-pressure hydraulic uses within spec limits.
• Temperature tolerance: The rated range of -40F to 250F means it holds up across cold starts and high-heat engine bays.
• One-piece full flow: The integrated design with a thickened curvature reduces turbulence at the junction and helps maintain flow efficiency.

Who It's For

This fitting is aimed at DIY mechanics, custom shop technicians, and enthusiasts who need a compact, reliable barb-to-AN connection for rubber fuel lines. It works well in tight areas where a 150 degree push lock orientation and a single-piece assembly simplify routing and reduce assembly steps.

Those who need fittings for braided stainless lines, PTFE-lined hose, or non-fuel applications should look elsewhere, since the manufacturer specifies these barb fittings are intended for rubber fuel lines only and may not be optimal for other hose types.

Pros & Cons

Pros

• Solid construction from 6061-T6 aluminum gives durability without excessive weight.
• High max working pressure and wide temperature range make it versatile for engine bay conditions.
• One-piece full flow geometry improves internal flow and reduces potential restriction.
• Compact 150 degree orientation helps when space is limited.

Cons

• Designed only for rubber fuel lines, so it is not suitable for all hose types or every installation.
• Some users report mixed results on leak resistance if over-tightened or improperly clamped.
