Black 110mm Soil Pipe Strap Boss – 32mm / 36mm Solvent Waste Adapter

Black 110mm Soil Pipe Strap Boss – 32mm / 36mm Solvent Waste Adapter

Features

The black 110mm soil pipe strap boss provides a heavy-duty branch connection solution designed specifically to link a 32mm (36mm external diameter) basin waste pipe into a main 110mm / 4″ soil and vent system. Manufactured from robust black uPVC with a two-part strap design secured by bolts on either side, this fitting clamps firmly around your existing soil pipe to create a reliable entry point without cutting the main stack. Furthermore, it features a solvent weld connection system, including a solvent weld reducer that steps down to 36mm (suitable for 1 1/4″ nominal waste pipes), ensuring a permanent, chemically welded watertight seal. Because you receive a specialized two-part strap boss, you can easily add secondary waste inlets wherever needed. As a result, you achieve a professional, highly secure, and permanent plumbing installation.

• Standard 110mm to 32mm/36mm Sizing: Precision-engineered to clamp onto standard 110mm (4″) soil pipes and accept 32mm nominal waste pipe (measuring 36mm externally). Therefore, it guarantees an accurate cross-system connection.
• Two-Part Bolt-Fixed Design: Features a robust two-part strap body held securely by bolts on either side. Consequently, it delivers a strong mechanical clamp around the soil pipe for maximum stability.
• Solvent Weld Connection: Designed for secure solvent welding on both the boss inlet and the reducer ring. Moreover, it creates a permanent, fused chemical bond that prevents leaks under pressure.
• Durable Black Finish: Manufactured from high-grade rigid plastics finished in sleek black. As a result, it blends seamlessly with black soil and waste pipe systems for a clean, professional aesthetic.
• Ideal for Basin Connections: Specifically tailored for routing secondary wastewater from bathroom basins into the main soil stack. Furthermore, it ensures a tidy and efficient branch transition.

Details

Adding a secondary basin waste pipe into an existing 110mm soil stack often requires a reliable branch connection that can be installed without dismantling the entire drainage run. Moreover, getting the exact size right for 1 1/4″ pipes can be tricky since nominal sizes differ from actual external measurements.

Fortunately, this black 110mm strap boss solves the problem with professional efficiency. Because it features a two-part bolted clamp, a durable solvent-weld system, and a 36mm reducer tailored for standard 32mm waste pipes, it creates an immediate, permanent branch inlet. Consequently, you achieve a clean, secure, and professional system transition.
