QUICK ACTUATING FITTING FOR CORRUGATED STAINLESS STEEL TUBING

摘要

A fitting (14) incorporating a quick actuating sealing and locking device and methods of actuating the fitting and forming a seal between a length of corrugated tubing (10) and the fitting (14) are provided. The tubing (10) c an be corrugated stainless steel tubing having a jacket (12) that at least p artially covers the tubing. The sealing and locking device incorporates a se aling ring (24) and a loading ring (26)- received in the fitting (14), the s ealing ring (24) being compressible against an end corrugation of the tubing -. The loading ring (26) can be actuated to move axially and engage the seal ing ring (24), thereby compressing the sealing ring (24) into substantial en gagement with the end corrugation.
