Plug and socket connector for compressed air lines has sealing rings on outside of plug, lower ring having sufficient resistance to radial stretching to prevent it being blown out of groove by compressed air

摘要

The plug (2) and socket (1) connector for compressed air lines has spaced sealing rings (21, 22) fitted in grooves on the outside of the plug. The lower ring (21), which is introduced into the socket first, has sufficiently high resistance to radial stretching to prevent it being blown out of the groove by compressed air while the connection is made.
