Black 110mm Soil Pipe Adapter Reducer – 55mm Solvent Waste Pipe Fitting

Black 110mm Soil Pipe Adapter Reducer – 55mm Solvent Waste Pipe Fitting

Features

The black 110mm soil pipe adapter reducer provides a reliable connection solution designed specifically for routing larger 55mm waste pipes into main 110mm soil and vent systems. Manufactured from durable, high-grade black uPVC, this adapter features a plain-ended spigot designed to push straight into a standard 110mm soil socket, such as those found on tees or elbows. Furthermore, it incorporates a solvent-weld boss reducer engineered to accept 55mm external diameter waste pipes—commonly referenced as 2″ or 50mm nominal sizing. Because the cap and reducer arrive unglued, you can easily apply your own solvent cement on site to establish a permanent, fused bond tailored to your exact plumbing layout. As a result, you achieve a professional, watertight, and tidy transition between major drainage branches.

• Standard 110mm Socket Spigot: Precision-engineered with a plain-ended spigot designed to insert smoothly into standard 110mm soil sockets. Therefore, it integrates effortlessly into existing drainage layouts.
• Suits 55mm External Waste Pipes: Perfectly sized to accommodate larger 55mm outer diameter waste lines (often classed as 2″ or 50mm nominal). Consequently, it connects heavy-flow appliances like baths, showers, and washing machines directly to the main stack.
• Permanent Solvent-Weld Design: Built for a glued connection between the reducer and cap. Moreover, it delivers a chemically fused, leak-free joint for long-term reliability.
• Durable Black uPVC Construction: Manufactured from weather-resistant, robust black plastic. As a result, it matches standard exterior soil and vent pipe installations seamlessly.
• Supplied Unglued for Flexibility: Delivered as separate components that fit together. Furthermore, it allows you to align and bond the fitting precisely during on-site installation.

Details

Connecting a large-bore 50mm or 2″ waste pipe from a bath, shower, or kitchen appliance into a standard 110mm soil stack often presents a sizing challenge. Moreover, forcing mismatched fittings together can result in chronic leaks and weak joints under high water volume.

Fortunately, this black 110mm soil adapter solves the problem with professional efficiency. Because it combines a secure spigot for 110mm sockets with a dedicated solvent-weld reducer for 55mm waste lines, it bridges high-flow drainage pipes cleanly. Consequently, you achieve a secure, professional, and permanent plumbing connection.
