12an StreetLite Crimp Fitting Straight

The 12AN StreetLite Crimp Fitting Straight by AEROQUIP is a purpose-built hydraulic hose adapter designed for high-performance automotive applications where reliability and compact design are non-negotiable. This straight crimp fitting serves as the backbone of fuel, oil, and coolant line systems in modified vehicles, street rods, and racing platforms that demand precision-engineered fluid management. Built for mechanics and enthusiasts who refuse to compromise on fitting integrity, the StreetLite series delivers the performance standards required for turbocharged engines, fuel injection systems, and custom plumbing configurations where failure is not an option.

AEROQUIP's StreetLite Crimp Fitting Straight utilizes a cold-crimp methodology that creates a permanent, leak-proof seal without the need for additional fittings or adapters. The 12AN port size (3/4-inch nominal) accommodates high-volume fluid flow in single-pass applications, making it ideal for fuel return lines, power steering circuits, and transmission cooler systems on both carbureted and fuel-injected engines. The straight configuration eliminates 90-degree bends, reducing turbulence and pressure drops while maintaining critical clearance around engine bay obstructions—a critical advantage when working with tight engine compartments in vintage restorations or modern engine swaps where routing flexibility is essential.

Professional mechanics and serious enthusiasts benefit most from this fitting when upgrading or restoring fuel systems, building custom cooling loops, or installing aftermarket hydraulic accessories on high-horsepower vehicles. The StreetLite design weighs just 0.16 lbs, minimizing parasitic weight while maintaining structural integrity under pressure spikes common in supercharged or turbocharged applications. This fitting pairs seamlessly with 12AN hose assemblies and works across a broad range of automotive fluids—gasoline, diesel, synthetic oils, and coolant—making it indispensable for any serious vehicle modification project that demands OEM-grade reliability in a compact, lightweight package.
