Straight Adapter Fitting -8AN x 3/4in NPT

The Vibrant Performance Straight Adapter Fitting -8AN x 3/4in NPT is a precision-engineered hydraulic adapter designed for custom fuel, oil, and coolant line routing in modified vehicles and high-performance engine builds. This fitting bridges the gap between -8 AN (AN8) hose connections and 3/4-inch NPT (National Pipe Taper) ports commonly found on fuel rails, filters, thermostats, and custom manifolds.

Crafted from aluminum with an anodized finish, the Vibrant straight adapter delivers durability and corrosion resistance in engine bay environments while maintaining a lightweight profile. The -8AN side accepts standard braided stainless hose or rigid aluminum tubing with -8AN male or female fittings, while the 3/4-inch NPT threaded port provides a secure, leak-tight interface with factory and aftermarket fuel system components.

Engine builders, fuel system tuners, and DIY enthusiasts benefit most from this adapter when converting older carb setups to EFI, installing adjustable fuel pressure regulators, or fabricating bespoke cooling circuits. The precision-machined design ensures proper sealing when paired with appropriate thread sealant or Teflon tape, critical for pressurized fuel systems where vibration and thermal cycling can compromise inferior connections.
