A preassembled fitting including a body (10), a nut (20) and a collet (40) positioned within the nut (20). The nut (20) is threaded on the body (10) a predetermined distance to allow the installer to snap the corrugated tubing (60) into the nut (20) and engage the collet (40). The nut (20) is then further tightened to seal the body (10) to the corrugated tubing (60). A tapered surface (16) on the body (10) engages the cut end of the corrugated tubing (60) and flares the cut end of the corrugated tubing (60). The fitting will make a metal to metal seal by folding the convolutions of the tubing (60) back against itself to create a double flare.
L'invention porte sur un raccord préassemblé comprenant un corps (10), un écrou et une douille (40) placée dans l'écrou (20). L'écrou (20) est fileté sur le corps (10) à une distance prédéterminée de façon à permettre à l'installateur d'encliqueter le tube ondulé (60) dans l'écrou (20) et d'engager la douille (40). L'écrou est ensuite serré de façon à bloquer hermétiquement le corps (10) sur le tube ondulé (60). Une surface conique (16) du corps (10) vient en contact et dilate l'extrémité découpée du tube ondulé (60). Le raccord forme un joint étanche métal-métal par le repliement des spires du tube ondulé (60) de façon à former un double évasement.
