Abstract

A fitting incorporating a crimp sealing device and a method of forming a seal between a length of corrugated tubing and the fitting are provided. A sealing crimp is formed over at least one corrugation of the tubing, where the sealing crimp can utilize a preformed bend or bulge to form a crimp and seal. Alternatively, the sealing crimp can apply pressure radially against an outer sleeve of the fitting, such that at least one corrugation of the tubing is compressed axially or radially to form a primary seal. The outer sleeve also can include one or more gaskets arranged between the outer sleeve and the tubing for forming a secondary seal. An inner sleeve can be received radially inside the outer sleeve, and one or more gaskets can be arranged between the inner sleeve and the tubing. Further, a jacket crimp can be applied against an end of the sleeve member to contact a jacket that at least partially covers the tubing.
