Plug-in pipe fitting with sealing O=rings

摘要

The plug-in connection is for a heating device in a building. It consists of a hollow plug unit (1) which has two successive sealing O-rings (7,8) set into square-section grooves in the outer diameter of the end surface which closely fits into the inner diameter of a plain socket or pipe. A shoulder on the socket has a small groove (9) in its ID. This may accommodate a clamping ring (17) which may be held in place by a clamping collar (13) with a retaining groove (16) on its inner diameter.
