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.

A crimping tool for securing a hose coupling to a non-metallic flexible hose to form a fluid-tight joint comprising: a frame having a main body portion and two leg portions extending generally transversely from opposite ends of said main body portion; first roller means in the form of a crimping die roller having two arcuate ridges separated by an arcuate groove, said groove extending radially inwardly from the base of said ridges, said ridges and groove having substantially the same radius; second roller means disposed opposite said first roller means; one of said first and second roller means being supported on a carriage movable relative to said frame for movement toward and away from the other of said roller means, said other of said roller means being supported by one of said leg portions; means on the other of said leg portions to move said carriage and one roller means toward the other of said roller means to force said crimping die roller into engagement with a hose coupling on a hose between said first and second roller means as said frame is rotated around said coupling and said one roller means is advanced to effect the crimping of said hose coupling against said hose and form a fluid-tight joint; and pre-calibrated crimp measuring means including a first pointer carried by said carriage and a first calibrated scale extending along one side of said main body portion that alines with said pointer to indicate the correct limit of movement for said one roller means to provide the correct amount of crimp for the particular size and type of hose and hose coupling being joined and a second pointer carried by said carriage and a second calibrated scale extending along the other side of said main body portion that aligns with said second pointer to provide the correct amount of crimp for a range of user selected hose sizes and hose couplings being joined.
