#12 120 Deg Startlite Crimp Fitting

The #12 120 Deg Startlite Crimp Fitting by AEROQUIP is a precision hydraulic hose connector designed for high-performance automotive and mechanical systems requiring reliable fluid transfer under demanding conditions. Built for professionals and enthusiasts who demand consistency in fuel, coolant, and hydraulic applications, this fitting serves as a critical junction point in custom engine builds, performance cooling systems, and fuel delivery modifications. Its 120-degree angle configuration allows for optimal routing in tight engine bays and complex plumbing layouts where standard 90-degree or straight fittings create clearance conflicts.

This crimp fitting features AEROQUIP's Startlite technology, which delivers superior seal integrity through a cold-crimp process that eliminates the need for solder or adhesive applications. The #12 size accommodates standard -12 hose (3/4-inch nominal diameter), making it compatible with mid to high-flow fuel systems and cooling circuits typical in LS engine conversions, twin-turbo builds, and competition vehicles. The 120-degree angle reduces stress points along the hose run by distributing pressure evenly and minimizing vibration-induced fatigue, extending hose life and preventing catastrophic leaks during sustained high-RPM operation.

Mechanics and fabricators benefit most from this fitting when designing custom fuel systems, intercooler circuits, and transmission cooler lines that must navigate around headers, turbos, and tight frame rails. The crimp design is reusable across multiple hose installations, making it economical for prototype work and motorsport applications where iterative testing is standard. Proper sizing and routing ensure maximum pressure capacity and flow efficiency—critical factors when upgrading fuel injectors, increasing boost levels, or adding auxiliary cooling capacity to turbocharged or supercharged powerplants.
