The 110mm Push-Fit Soil 87.5° Double Socket Branch (Grey, Ref: SPLG0010) is a heavy-duty uPVC soil and vent fitting designed to connect a secondary 110mm branch line into a main vertical 110mm soil stack. Engineered at an 87.5° angle (often designated as 92.5°), it provides the necessary continuous fall of 2.5° to ensure efficient, self-cleansing gravity drainage while preventing backflow into connecting sanitary appliances.
 
This double socket configuration features pre-lubricated, rubber ring seal sockets on the main horizontal branch entry and the top vertical socket, alongside a plain spigot end at the base. This design allows the lower spigot to slot directly into the socket of an underlying pipe or fitting, making it ideal for compact, continuous vertical stack runs. Integrated closed side bosses also allow for direct connections from smaller 32mm, 40mm, or 50mm waste lines using standard boss adaptors.
 
Manufactured from durable, high-impact uPVC in compliance with UK standards (BS EN 1329-1), the grey finish matches standard internal and external grey soil systems. The push-fit connection mechanism enables fast, dry assembly, ensuring a watertight and gastight joint while accommodating natural thermal movement along the soil pipe system.
