110mm Spare Inspection Chamber Blanking Plug

Product Description

Keep your drainage system tidy and secure with a 110mm Spare Inspection Chamber Blanking Plug. This simple yet essential fitting is used to blank off or seal unused or future inlets in chamber bases, hopper sockets, inspection chambers or similar pipework. It prevents ingress of dirt, water, rodents, or debris into unused sockets, maintaining the integrity and cleanliness of your drainage installation.

Manufactured from durable, rigid plastic (PVC-U / similar underground drainage-rated material), this plug is designed for underground exposure. It fits snugly into a 110mm socket or ring-seal opening, providing a tight seal that resists water penetration and soil infiltration. The plug’s design is straightforward — push-in or seat-in, often without needing adhesives or additional hardware, depending on the chamber system.

Because it’s a spare part, it’s ideal for maintenance, retrofitting, or preparing drainage systems for future expansion. If a socket is currently unused, inserting a banking plug is a quick, low-cost way to protect the system, without altering the base, the chamber, or disrupting pipework.

Key Features

• Designed for 110mm diameter sockets or openings.

Benefits

• Protection & cleanliness: Keeps unwanted materials out of unused inlets and helps prevent blockages or hygiene issues.

• Low cost maintenance: Far cheaper and quicker than replacing full parts or adapting the chamber base.

• Future flexibility: If you later need that inlet, the plug can be removed rather than replaced part of the installation.

• Improved water tightness: Helps maintain the sealed nature of the chamber or inlet, reducing leaks or groundwater ingress.

• Reduced installation effort: Very easy to fit — minimal tools, no complex sealing required in many cases.
