A fitting incorporating a bushing for forming a seal between a length of corrugated tubing and the fitting, and methods of actuating the fitting and forming a seal using the fitting and tubing are provided. The tubing can be corrugated stainless steel tubing having a jacket that at least partially covers the tubing. The fitting includes a bushing having a substantially open configuration, the bushing configured to engage at least one corrugation groove. When a nut is advanced, the bushing applies pressure to the tubing to crush at least one initial corrugation to form a metal-to-metal seal that is gas and liquid tight.
La présente invention concerne un montage incorporant une bague destinée à former un joint entre une longueur de tubage ondulé et le montage, et des procédés d'actionnement du montage et de formation d'un joint en utilisant le montage et le tubage. Le tubage peut être un tubage en acier inoxydable ondulé présentant une chemise qui recouvre au moins en partie le tubage. Le montage comporte une bague présentant une configuration sensiblement ouverte, la bague étant configurée pour se mettre en prise avec au moins une rainure d'ondulation. Lorsqu'un écrou est avancé, la bague applique une pression sur le tubage pour écraser au moins une ondulation initiale pour former une étanchéité métal contre métal qui est étanche au gaz et au liquide.
