Lever-Operated Crimpers with Dies

Crimpers are furnished with five removable dies that crimp air and water hose. Place your hose, ferrule, and barbed fitting into a die that's inserted in the crimper. Press the lever to crimp the fitting onto the hose. Fasteners not included. Hose OD compatibility is measured without the fittings installed.

Individual dies (sold separately) allow you to crimp sizes of air and water hose from 0.385" to 0.843" OD.
