Abstract:
1. A compression tool for compressing and flattening a first end of corrugated tubing having a series of corrugations running along the outside thereof, said compression tool comprising: a force-transmission body having a threaded bore running therethrough and a correspondingly threaded force-transmitting driver received by said threaded bore, said force-transmitting driver having a compression head at the front thereof and a coupler at the rear; a deburring rim carried by said compression head at the front of the threaded force-transmitting driver of said force-transmitting body so that said deburring rim lies in front of said compression head; and a clamp to hold the first end of said corrugated tubing in stationary axial alignment with the compression head of said force-transmitting driver, such that a rotational force applied to the coupler at the rear of said force-transmitting driver causes said force-transmitting driver to rotate and move axially through the threaded bore of said force-transmission body, whereby the compression head at the front of said force-transmitting driver is correspondingly moved towards and into contact with the first end of the corrugated tubing to compress and flatten said first end, said deburring rim moving with said compression head so as to lie inwardly of and rotate within the first end of the corrugated tubing to remove burs therefrom at the same time that said compression head compresses and flattens said first end.
