The RUSSELL #12 Crimp Collar 6pk is a set of six replacement crimp collars sized for -12 AN rubber hose assemblies. These collars are the sleeve that gets crimped over the hose and barb on RUSSELL ProClassic-style crimp hose ends, holding the connection together under fluid pressure. If you build or repair braided and rubber-covered fuel, oil, or coolant lines, these are the consumable piece you replace each time you cut and re-terminate a -12 line. Buying them in a six-pack means you have spares on the bench for multiple hose ends in a single build. Browse the full fittings, hoses, and valves selection to match the rest of your -12 system.
Each collar is engineered to capture -12 rubber hose against the matching crimp-style hose end barb. The crimp collar works by being compressed in a hydraulic or pneumatic crimp die, which deforms the collar evenly around the hose to create a leak-resistant mechanical lock. That makes proper collar sizing critical: a -12 collar pairs with -12 hose and -12 ends, and mixing sizes will not seal correctly. These are crimp-only collars, not field-attachable reusable fittings, so they are intended for shops and builders running a dedicated crimping machine. The six-pack quantity suits multi-line projects where every hose end needs a fresh collar. Pair these with the correct -12 straight hose end and run them on -12 hose.
Reach for these collars when terminating -12 fuel, oil cooler, or power steering lines on race cars, hot rods, and custom builds where crimp-style assemblies are preferred over reusable hose ends. Because crimped joints can't be loosened by vibration the way a poorly torqued reusable end can, many builders favor them on high-output and competition setups. Keep a stock of collars on hand so a single damaged hose doesn't stall a project. When you're sourcing the rest of a -12 line, check our -12 hose options and matching -12 unions to complete the run.
These are -12 (#12) crimp collars, sized to fit -12 AN rubber hose and matching -12 crimp-style hose ends. Collar size must match both the hose and the hose end. A -12 collar will not seal correctly on a -10 or -16 line, so confirm your hose size before ordering.
This is sold as a six-pack, giving you six individual #12 crimp collars. That covers multiple hose ends on a single build or leaves spares on the bench for future repairs and re-terminations.
No. Crimp collars are designed to be compressed in a hydraulic or pneumatic crimping machine using the correct die for the hose size. The machine deforms the collar evenly around the hose and barb to form a leak-resistant lock. They are not field-attachable reusable fittings.
Reusable hose ends thread onto the hose with a socket and nipple and can be removed by hand. Crimp collars are a permanent, machine-crimped connection. Many builders favor crimped joints on high-output and competition setups because they resist loosening from vibration.
