Abstract

A preassembled fitting including a body, a nut and a collet positioned within the nut. The nut is threaded on the body a predetermined distanced to allow the installer to snap the corrugated tubing into the nut and engage the collet. The nut is then further tightened to seal the body to the corrugated tubing. A tapered surface on the body engages the cut end of the corrugated tubing and flares the cut end of the corrugated tubing. The fitting will make a metal to metal seal by folding the convolutions of the tubing back against itself creating a double flare.
