Abstract: A coupling and method of coupling of a self-aligning self-tightening nature is obtained by providing a nipple with a hose receiving end and a coupling end. An annular hose abutment flange directed outwardly is formed on the nipple remote from the hose receiving end. An annular pressure ramp is formed on the nipple intermediate the hose receiving end and the hose abutment flange. A plurality of grip segments having a hose receiving end and a coupling end are provided with at least one annular node and an inwardly directed alignment flange. A hose is slid over the hose receiving end of the nipple toward the abutment flange, and the grip segments are placed over the hose with the inwardly directed annular alignment flange located between the outward abutment flange and the coupling end of the nipple. The grip segments are tightened on the hose and nipple, thus forcing the grip segments toward the coupling end by squeezing the hose between the ramp and the node.

Abstract: A coupling and method of coupling thin-walled/tubing and the like includes an inner member and an outer member in the form of a sleeve or band surrounding the inner member with the tubing therebetween. The inner member is provided with a pair of tubing grooves and a seal receiving groove between the two tubing grooves or at least between one groove and the tube receiving end of the coupling. By means of annular ridges, the tubing is forced into the tubing grooves, and by means of an annular ridge the tubing is pressed tightly against the seal in the seal receiving groove, thus forming a fluid-tight coupling member.

Abstract: A coupling and method of coupling thin-walled/tubing and the like includes an inner member, an intermediate wedge member and an outer member in the form of a sleeve surrounding the intermediate and inner members with the tubing therebetween. The inner member is provided with a pair of tubing grooves and a seal receiving groove between the two tubing grooves or at least between one groove and the tube receiving end of the coupling. By means of annular ridges on the intermediate wedge member the tubing is forced into the tubing grooves, and by means of an annular ridge on the wedge the tubing is pressed tightly against the seal in the seal receiving groove, thus forming a fluid-tight coupling member.

Abstract: A coupling and method of coupling thin-wall hose/tubing and the like includes an inner member, a sleeve surrounding the inner member and the tubing therebetween. The inner member is provided with a pair of tubing grooves and a seal material between the grooves. By means of compression rings or annular ridges the tubing is forced into the tubing grooves and stretched across the seal, thus forming a fluid-tight coupling member.
