Used to bring horizontal and vertical pipe runs together, usually when connecting a pipe from a WC into the main soil stack. The 112.5 degree angle introduces a steeper fall to the horzizontal run than a standard 92.5 degree branch.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.The circular bosses on either side of the branch can be drilled out and used in conjunction with our SP10, SP11 and SP12 Boss Adaptors to introduce a 32mm, 40mm or 50mm waste pipe into the soil stack.
