Floplast Soil 110mm Black Strap Boss

The 110mm Strap-On Boss is the most efficient solution for adding new bathroom or kitchen waste connections to an existing soil system. Instead of removing large sections of pipe to install a fixed boss pipe, this “strap-on” version can be fitted directly onto a 110mm pipe. Simply cut a hole in the existing soil stack using a hole saw, apply solvent cement, and “strap” this fitting around the pipe to create a permanent, leak-proof branch. Manufactured from high-impact, UV-stabilised black PVC-U, this fitting is designed for both internal and external use. It features a compact, modern design that remains within British Standard specifications, ensuring it fits neatly even in tight spaces. The boss is designed with a built-in 2.5° fall to ensure correct drainage flow from the waste pipe into the main stack. It is fully compatible with FloPlast, Polypipe, and other leading 110mm soil systems, making it a universal choice for plumbers and DIYers alike. Ideal for Retrofitting: Allows you to add a new waste inlet to an existing 110mm soil stack without the need for major dismantling or pipe replacement. Easy Installation: Features a simple wrap-around strap design that provides a tight, reliable mechanical and chemical (solvent weld) connection. High Temperature Resistance: Suitable for high-temperature waste discharges from washing machines, dishwashers, and boiling water taps. Versatile Sizing: Accepts standard push-fit or solvent-weld boss adaptors for 32mm, 40mm, and 50mm waste pipes. Professional Finish: The high-gloss black finish matches standard black soil systems, providing a tidy and cohesive look for external pipework.
