Ring Seal Soil Branch is used to bring horizontal and vertical pipe runs together, usually when connecting a pipe from a WC into the main soil stack. The 135 degree angle introduces a steeper fall to the horizontal run than a standard 92.5 or 112.5 degree branch. It is most commonly found on the outside wall of a building, often on blocks of flats or apartments.
The top two connections are ring seal sockets, the bottom of the branch is a spigot that can be fitted into another ring seal or solvent weld socket.
