The 110mm Push-Fit Soil 45° Double Socket Branch (Black, Ref: S27 / SPB0014) is a heavy-duty uPVC soil and vent fitting designed to connect a secondary 110mm branch line into a main 110mm vertical stack or horizontal drainage line at a 45° angle. The gradual 45° junction angle optimizes fluid dynamics, promoting smooth flow and reducing turbulence to prevent blockages during high-volume waste discharge.
 
This double socket configuration is engineered with integrated rubber ring seal sockets on both the top main vertical entry and the 45° branch inlet, combined with a plain spigot end at the base. This layout enables the lower spigot to slide directly into the socket of an underlying pipe or fitting, making it ideal for compact stack runs and angled offsets. Closed side bosses are also integrated into the body, allowing for direct connection of smaller 32mm, 40mm, or 50mm waste lines using standard push-fit boss adaptors.
 
Manufactured from durable, high-impact, UV-stabilized uPVC to UK standards (BS EN 1329-1), the black finish makes it suitable for both external soil stacks exposed to sunlight and high-visibility internal installations. The push-fit socket mechanism delivers a reliable watertight and gastight seal without solvent welding, while allowing natural thermal expansion and contraction within the drainage system.
