Grey 110mm Soil Pipe Adapter Reducer – 55mm Push-Fit Rubber Waste Fitting

Grey 110mm Soil Pipe Adapter Reducer – 55mm Push-Fit Rubber Waste Fitting

Features

The grey 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 grey uPVC fitted with a black rubber boss reducer, 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 an integrated rubber seal engineered to grip 55mm external diameter waste pipes—commonly referenced as 2″ or 50mm nominal sizing. Because it uses a flexible push-fit rubber connection rather than solvent glue, you can install, adjust, or dismantle the waste line quickly and cleanly without chemical sealants. As a result, you achieve a professional, watertight, and flexible transition between heavy-flow appliances and main 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 grey drainage layouts.
• Suits 55mm External Waste Pipes: Perfectly sized with a black rubber seal to accommodate larger 55mm outer diameter waste lines (often classed as 2″ or 50mm nominal). Consequently, it connects baths, showers, and utility appliances directly to the main stack.
• Flexible Push-Fit Rubber Design: Built with a resilient rubber collar that grips waste pipe securely without glue. Moreover, it allows for fast, tool-free adjustments and future maintenance.
• Durable Grey uPVC Construction: Manufactured from weather-resistant, robust grey plastic. As a result, it matches standard exterior soil and vent pipe installations seamlessly.
• Clean and Adjustable Fitting: Delivered ready for immediate push-fit installation. Furthermore, it enables easy on-site positioning without the mess of solvent cement.

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, dealing with permanent glued joints can make future maintenance or alterations difficult.

Because it combines a secure spigot for 110mm sockets with a flexible push-fit rubber reducer for 55mm waste lines, it bridges high-flow drainage pipes cleanly. Consequently, you achieve a secure, professional, and easily manageable plumbing connection.
