Abstract
A compression tool for compressing and flattening one or both ends of a length of corrugated tubing commonly used for making solar installations. A threaded force-transmitting driver is located within a threaded bore of a force-transmission cylinder. A clamp is disposed in surrounding engagement with the corrugated tubing. Tube retaining lips of the clamp are received between an adjacent pair of corrugatings to hold one end of the corrugated tubing in stationary axial alignment with the force-transmitting driver. A rotational force applied to the threaded force-transmitting driver causes the driver to rotate and move through the threaded bore of the force-transmission cylinder. A compression head at the front of the driver is correspondingly moved towards and into contact with the end of the tubing to compress and flatten the end to prevent a nut from sliding off the tubing.
