Product Overview
110mm Socket Plug designed to seal the socket of an underground drainage fitting or pipe, either permanently or temporarily during installation and testing. By closing off unused sockets, it prevents water ingress, foul odours, and debris from entering the system.
Manufactured from durable uPVC and available in grey, white, or anthracite finishes, the plug fits directly into 110mm push-fit sockets to create a secure, watertight seal without the need for specialist tools.
Socket plugs are commonly used to cap future connection points, isolate branches during construction, or close off lines for air or water pressure testing, ensuring flexibility and reliability in underground drainage layouts.
