Abstract

1304374 Sealing rings; pipe couplings GERMANY MINISTRY OF TRANSPORT 3 Feb 1970 5041/70 Headings F2B and F2G A sealing ring for air line couplings on railway vehicles, comprises a sealing lip 7 having a sealing surface 3 for engaging a similar surface of a counter coupling ring (not shown) and a surface 1 for bearing against an air pipe 2. The outer ring surface has slots 8, and engages in a groove of the pipe 2, and radial recesses 5 of the surface 1 lead the line pressure into a cavity 10 to enhance sealing.
