#12 45 Deg Hose Fitting P/C Crimp-On

The #12 45 Deg Hose Fitting P/C Crimp-On from RUSSELL is a precision-engineered hydraulic hose adapter designed for high-performance fuel, coolant, and brake line applications in modified vehicles. Built for automotive enthusiasts and fabricators who demand reliability under pressure, this 45-degree crimp-on fitting transitions 12 AN hose connections with the directional control that tight engine bays and custom plumbing layouts require. Whether you're upgrading a fuel system in a high-horsepower build or routing brake lines around a turbocharger installation, this fitting eliminates the need for bulky bend-radius hose runs that consume valuable underhood real estate.

This fitting features a 12 AN male crimp end that accepts standard -12 hose with a corresponding 12 AN female port, delivering a sealed 45-degree directional change in a compact aluminum body. The black and silver anodized finish provides corrosion resistance in aggressive underhood environments while the crimp-on design eliminates the need for JIC (37-degree) sealing surfaces—critical for maintaining system integrity at elevated pressures common in turbocharged and supercharged applications. The aluminum construction keeps weight minimal without compromising strength, and the 45-degree geometry allows for efficient path routing that reduces hose kinking and pressure losses compared to multiple 90-degree elbows.

This adapter suits custom fuel system builds, aftermarket cooling configurations, and brake line relocations where space constraints demand angled connections. Installation requires proper hose crimping equipment and a compatible 12 AN hose with internal diameter and wall thickness matching RUSSELL's specifications. For street and track vehicles using braided stainless steel or reinforced rubber hose, ensure your crimper is calibrated to the fitting manufacturer's torque and compression settings to prevent leaks under boost or hard braking. Stock this fitting for any serious engine bay modification project that calls for leak-free, directional hose routing.
