Grey 110mm Soil Pipe Adapter Reducer to 40mm Waste Pipe – Push-Fit Rubber

Grey 110mm Soil Pipe Adapter Reducer to 40mm Waste Pipe – Push-Fit Rubber

Features

The grey 110mm soil pipe adapter reducer provides a reliable connection solution designed specifically to connect standard 40mm waste pipes (from baths, showers, kitchen sinks, washing machines, or dishwashers) into a main 110mm / 4″ soil and vent system. Manufactured with a robust grey body and a flexible black rubber boss reducer, this fitting ensures a secure, watertight seal without the need for complex solvent welding. Furthermore, it features a plain-ended spigot design that pushes directly into any standard 110mm soil pipe socket or branch fitting (such as a tee or elbow). Because you receive a specialized adapter, you can easily tie larger appliance waste lines into main drainage stacks. As a result, you achieve a professional, highly reliable, and leak-free plumbing installation that stands the test of time.

• Standard 110mm to 40mm Sizing: Precision-engineered with a 110mm (4″) spigot end to fit standard soil pipes and a rubber reducer designed to securely grip 40mm high-capacity waste pipes. Therefore, it guarantees a snug, accurate cross-system connection.
• Push-Fit Rubber Seal Design: Features an integrated flexible black rubber boss insert. Consequently, it creates a tight, compression-fit grip around the waste pipe and eliminates the need for messy glues or sealants.
• Plain-Ended Spigot Connection: Designed with a spigot end that slots directly into any standard 110mm socket, soil pipe, or socketed branch fitting. Moreover, it allows for quick and straightforward positioning within existing drainage runs.
• Durable Weather-Resistant Construction: Manufactured from high-quality rigid plastics and resilient rubber. As a result, it resists chemical corrosion, temperature fluctuations, and daily wear from heavy wastewater.
• Ideal for Multi-Appliance Connections: Specifically tailored for routing secondary waste water from baths, showers, sinks, or utility appliances into the main soil stack. Furthermore, it ensures a tidy and efficient transition.

Details

Connecting high-capacity waste pipes—such as those from kitchen sinks, baths, showers, or washing machines—into a main 110mm soil and vent stack requires a secure adapter that prevents foul air leakage while accommodating larger pipe diameters. Moreover, makeshift sealing methods can easily fail or cause blockages under heavy water pressure.

Fortunately, this grey 110mm soil pipe adapter reducer solves the problem with professional efficiency. Because it features a plain-ended spigot for standard soil sockets and a flexible black rubber boss for 40mm waste pipes, it creates an immediate, watertight barrier. Consequently, you achieve a clean, secure, and permanent system transition.
