#10 Crimp Collars 6pk

The #10 Crimp Collars 6pk by Russell are essential fittings for anyone building or repairing custom hydraulic and fuel line systems on performance vehicles. These aluminum crimp collars are specifically engineered to work with #10 AN (Army-Navy) hose sizes, the industry standard for high-pressure applications in engine bays, fuel systems, and transmission coolers. Whether you're fabricating a custom fuel rail setup, upgrading cooling lines on a turbo engine, or restoring a classic car's original hydraulic brake system, this six-pack provides the quantity you need to complete professional-grade installations without repeat orders.

Russell's #10 crimp collars are manufactured from aluminum in a natural finish, delivering a lightweight yet durable connection point that resists corrosion in engine compartments and underbody environments. The crimp-on design means these collars compress onto the hose barb under controlled pressure, creating a mechanical lock that prevents hose separation even under vibration and thermal cycling—critical for safety-sensitive systems like fuel delivery and cooling. The natural aluminum construction allows for easy inspection and modification if needed, and these collars integrate seamlessly with standard hose barbs and fittings found in any serious automotive machine shop or DIY fabrication setup.

Professional mechanics, engine builders, and dedicated automotive enthusiasts rely on Russell crimp collars to ensure leak-free, reliable connections in custom fuel systems, intercooler setups, and cooling loops where OEM components don't fit the application. The compact dimensions (2.65 x 1.65 x 4.85 inches) and lightweight profile (0.07 lbs per pack) make these collars ideal for tight engine bay layouts where space is at a premium. Install using a proper hose crimper tool and cut the hose to length before assembly—this method delivers superior hold compared to worm clamps and eliminates the risk of hose bulging or flow restriction.
