Grey Push-Fit 110mm Drain Adapter with 40mm Waste Boss Connection

Features

This grey push-fit drain adapter with a 40mm waste boss provides a versatile, professional plumbing solution designed to connect standard 4-inch / 110mm plastic PVC pipework to older drainage systems while allowing an auxiliary waste connection. Manufactured from durable grey polypropylene, this connector features a reliable internal ‘O’-ring seal socket for BS 4514 pipework, a multi-finned seal spigot for internal insertion into legacy cast iron, plastic, or clay pipes, and an integrated 1 1/2″ (40mm) boss inlet. Furthermore, it allows you to tie secondary appliance waste into your main stack easily. As a result, you achieve a secure, multi-functional transition for complex plumbing layouts.

• Integrated 40mm Waste Boss: Features a built-in 1 1/2″ boss connection. Therefore, it allows you to plumb auxiliary waste pipes from basins, baths, or utility appliances directly into the main drainage line.
• Universal Transition Fit: Engineered to bridge modern 110mm PVC pipework with older clay, cast iron, or plastic drain runs. Consequently, it simplifies retrofitting and low-level alterations.
• Finned Seal Spigot: Equipped with a flexible multi-finned spigot that grips securely inside existing legacy pipes. Moreover, it creates a high-integrity friction seal against uneven inner diameters.
• Secure O-Ring Socket: Features a reliable ‘O’-seal socket tailored to standard 4-inch / 110mm pipe conforming to BS 4514. As a result, it guarantees a leak-resistant joint under normal flow conditions.
• Durable Polypropylene: Built from high-grade, weather-resistant grey polymer. Furthermore, it withstands ground pressure and subterranean environments without degrading.

Details

Connecting a modern 110mm drainage stack while trying to feed an additional waste pipe from a nearby appliance into the same line can often require messy multi-fitting modifications. Moreover, cramped spaces beneath floors or low-level runs make adding separate branch connections difficult.

Fortunately, this grey push-fit drain adapter with a 40mm waste boss solves the problem with professional efficiency. Because it combines a standard 110mm-to-legacy transition connector with an integrated 1 1/2″ boss inlet, it handles both jobs in a single component. Consequently, you achieve a clean, compact, and watertight multi-service drainage connection.
