ABSTRACT:
The problem of hose breakdown in the field is solved by a hand-held crimping tool according to the present invention. The crimping tool disclosed has a frame with two leg portions projecting out from the ends. A crimping die roller including two arcuate ridges separated by an arcuate groove co-operates with two spaced rollers that move with a carriage. The carriage is advanced and retracted by a threaded shaft. The crimping die roller is supported on one leg portion and a threaded shaft on the other leg that moves the carriage. A pre-calibrated crimp measuring means on the tool provides the exact amount of crimp for each fitting and hose.
