Key Features
-
Precision Fit: Converts carburetor male inlet threads to AN hose connections for popular Holley, Edelbrock, Demon, and Quick Fuel carburetors. Designed for easy integration with braided fuel lines and custom AN routing setups.
-
Dual-Seal Design: A side seal at a 37-degree flare cone for leak-free high-pressure connection. The carburetor side uses an aluminum crush gasket for an end-face compression seal. Do not overtighten — tighten until snug to avoid cracking the washer.
-
CNC-Machined 6061-T6 Aluminum: CNC-machined from solid 6061-T6 billet with black anodized surface treatment. Corrosion-resistant, lightweight, and built for harsh under-hood environments from -65°F to 250°F.
-
1,500 PSI Rated: Max working pressure of 1,500 PSI. Suitable for EFI fuel lines, braided hose setups, turbo oil feeds, clutch lines, and nitrous systems — not just carburetors.
-
Easy DIY Install: Requires only basic hand tools. Apply a small amount of assembly lube to threads to prevent galling during installation. No special equipment needed.
