Black 110mm to 43mm (1 1/2″) Soil Pipe Reducer Cap

Black 110mm to 43mm (1 1/2″) Soil Pipe Reducer Cap

Features

This black 110mm soil pipe reducer cap provides a robust, professional plumbing solution designed specifically to reduce a standard 4″ main soil and vent line down to a 43mm (1 1/2″) solvent waste connection. Manufactured from durable black polymer, this versatile fitting can be pushed into a ring-seal socket or permanently cemented into a glued socket, while the 43mm outlet requires solvent welding prior to installation. Furthermore, its clean black finish matches standard UK exterior drainage systems seamlessly. As a result, you achieve a neat, airtight, and secure transition for secondary waste lines feeding into your main stack.

• Standard 110mm Soil Sizing: Engineered to fit standard UK 4″ (110mm) soil and vent pipe systems. Therefore, it integrates smoothly with existing drainage stacks.
• Reduces to 43mm Waste Pipe: Features a stepped reduction down to a 1 1/2″ connection (measures 43mm externally). Consequently, it accommodates standard solvent waste pipes perfectly.
• Flexible Installation Options: Can be pushed directly into a rubber ring-seal socket or permanently solvent-cemented into place. Moreover, it offers maximum versatility on site.
• Durable Black Polymer: Built from high-grade, weather-resistant plastic designed for exterior use. As a result, it withstands UV exposure, frost, and long-term weathering without degrading.
• Secure Solvent Weld Design: The reducer outlet requires solvent glue for a watertight bond. Furthermore, it ensures a permanent, leak-proof link for waste water entry.

Details

Tying a secondary waste line from a basin, sink, or appliance into a main 110mm soil and vent stack often requires a specialized reducer fitting to bridge the size gap securely. Moreover, using poorly matched adapters can lead to foul odors, gas leaks, or loose pipe connections on exterior or interior stacks.

Fortunately, this black 110mm soil pipe reducer cap solves the problem with professional efficiency. Because it steps a standard 4-inch stack down to a 43mm solvent waste connection using a durable polymer build, it delivers a rigid, airtight link. Consequently, you achieve a clean, professional, and reliable drainage transition.
