Title: Gas dispensing line coupling - elastic sleeve expanded into sealing contact with pipe by supplied gas
Inventor: REMANE ROGER
IPC: A61D7/00
Filed: 1973-11-02
Abstract: Gas dispensing line coupling produces a sealed connection when the line is inserted into a pipe branch connection for delivery purposes. The coupling incorporates an elastic sleeve which is fixed permanently to the line and is brought into contact with the interior of the branch pipe so that the pressure of the dispensed or tapped gas forces the sleeve into tight contact with the pipe. The coupling should embody a chamber containing one end of the elastic sleeve and should also have a core or plug member held inside the sleeve and fixed to the body forming the chamber. This plug compresses the sleeve between itself and the surrounding wall so that sleeve and plug are led out from the body and re-engaged inside the pipe.
