The 110mm Push-fit Soil 87.5° Triple Socket Branch (Grey, Ref: SPLG0009) is a heavy-duty uPVC soil and vent fitting designed to connect a branch pipeline into a vertical or horizontal $110\text{mm}$ main soil stack. Engineered with an $87.5^\circ$ angle, it provides a subtle $2.5^\circ$ fall, ensuring self-cleansing gravity drainage for waste discharge while preventing backflow into connecting fixtures.
 
Featuring a triple-socket design, all three connection points are fitted with integrated, captivated rubber ring seals that create a watertight and gastight push-fit joint. This push-fit mechanism eliminates the need for solvent welding, allowing for thermal expansion and contraction along the pipe run while speeding up site assembly.
 
Manufactured from durable, weather-resistant uPVC to meet relevant UK standards (such as BS EN 1329-1), this fitting is fully suitable for internal soil stacks as well as external soil and vent installations. Its industry-standard $110\text{mm}$ size ensures seamless compatibility with plain-ended or socketed push-fit soil systems across domestic and commercial sanitary applications.
