Crimp Collar #6 Sport Crimp (1pk)

The Crimp Collar #6 Sport Crimp is a precision-engineered aluminum fitting designed for high-performance fuel, oil, and coolant line systems in custom automotive builds. Built by FRAGOLA, a trusted name in performance hydraulic solutions, this crimp collar serves as the foundational component in secure hose assembly for racing, street performance, and professional shop applications. Whether you're building a custom fuel system for a show car, upgrading cooling lines on a turbocharged engine, or fabricating brake and power steering systems, the #6 AN-size crimp collar ensures leak-free, vibration-resistant connections that withstand extreme pressure and temperature cycles.

This natural aluminum crimp collar is engineered to work in concert with FRAGOLA hose and fittings, using a mechanical crimp process that compresses the collar onto reinforced hose to create a permanent, pressurized seal. The #6 AN size corresponds to a 3/8-inch nominal hose diameter, making it ideal for mid-range flow applications in fuel delivery, engine cooling, and transmission cooling circuits. The sport-crimp design provides superior holding strength compared to push-lock alternatives, eliminating the risk of hose separation under load. Weighing just 0.03 pounds per collar, aluminum construction keeps overall system weight minimal while delivering reliability that matches or exceeds steel fittings in corrosion-resistant performance.

Mechanics and fabricators working on fuel-injected engines, LS swaps, and custom cooling systems rely on this crimp collar as part of a complete hose assembly kit. Each single-pack collar is compatible with standard hose crimping tools and FRAGOLA's modular fitting system, allowing for repeatable, professional-grade line assembly in your shop or garage. Installation requires proper hose preparation, fitting insertion, and a precision crimp tool—the mechanical nature of the connection ensures it won't loosen from vibration or thermal cycling, making it superior for race cars, hot rods, and daily-driven performance vehicles exposed to demanding conditions.
