This 92.5 degree branch is one of the integral parts of any soil pipe system. It is used to bring horizontal and vertical pipe runs together, usually when connecting a pipe from a WC into the main vertical soil stack. The 92.5 degree angle creates a fall that is self-cleansing.
The top two connections are ring seal sockets, the bottom of the branch is a spigot that can be fitted into another ring seal socket.
