ABSTRACT:
A connector for connecting corrugated tubing to pipes or fittings permits the corrugated tubing to be used without any modification to its ends. The corrugated tubing need only be cut to length by severing at a "valley" of one of the corrugations. A ferrule in the form of semi-annular half-sections is fitted about the endmost corrugations of the severed tubing. Inwardly extending projections of the ferrule engage at least one of the valleys to prevent relative axial movement between the ferrule and the tubing. A retainer nut previously placed over the tubing is slipped over the ferrule to retain the ferrule in place. An outwardly extending portion of the ferrule engages an inner portion of the nut to prevent axial movement of the nut over the ferrule. An O-ring or other sealing member may be inserted within the retainer nut and positioned against the endmost corrugation of the tubing. Thereafter, the retainer nut can be threaded about an existing pipe or fitting and tightened in place until deformation of the end corrugation and/or the sealing member occurs. A fluid-tight seal results. Various embodiments of the invention are disclosed, including several especially adapted for securing a covering of braided wire about the tubing without the need for welding the covering to the connectors. In the braided wire embodiments of the invention, the covering is inserted intermediate a specially configured retainer nut and the outer corrugations of the tubing. The retainer nut clamps the covering in position relative to the retainer nut and the tubing.
