12AN Crimp Style Hose End Black STR

The 12AN Crimp Style Hose End Black STR from Redhorse Performance is a precision-engineered fitting designed for high-pressure fuel, coolant, and brake line applications in custom automotive builds and engine modifications. This component is essential for builders who demand reliable, leak-free connections in turbocharged, supercharged, or heavily modified vehicles where OEM hose routing falls short. Whether you're upgrading a fuel system on a street car or fabricating custom cooling lines, this hose end delivers the security and durability required in demanding motorsport and street performance applications.

The 12AN crimp-style design uses a mechanical swage connection that permanently compresses onto braided stainless steel or nylon hose, creating a vibration-resistant, pressure-rated seal without reliance on threaded compression fittings that can loosen under engine bay heat and vibration. The black finish enhances aesthetic integration into engine compartments. Redhorse Performance hose ends are manufactured to SAE J518 standards, ensuring consistent wall thickness, bore concentricity, and burst ratings that exceed typical OEM specifications—critical when running elevated fuel pressures, coolant temperatures, or brake fluid temperatures beyond factory limits.

This fitting is ideal for custom fuel system builders, performance technicians, and engine builders constructing bespoke setups. It is particularly beneficial for those looking to enhance the performance and reliability of their vehicles under demanding conditions. With its robust design and compatibility with various hose types, the 12AN Crimp Style Hose End is a must-have for serious automotive enthusiasts.
