Description
The 160mm access plug is an underground drainage fitting used to close off a 160mm socket while still allowing future access to the drainage run. It is suitable for larger foul water and surface water drainage systems where a removable inspection or rodding point is required.
This screwed access plug is designed for use with compatible 160mm underground drainage pipework and fittings. The spigot end fits into a suitable 160mm socket, while the screwed cap can be removed when access is needed for inspection, cleaning or maintenance.
It is a practical fitting for builders, groundworkers, landscapers and drainage installers working on larger domestic, commercial and site drainage layouts. It helps keep the drainage system closed and protected while still allowing access if the pipe run needs attention later.
160mm Access Plug for Underground Drainage
The 160mm access plug is used where a 160mm underground drainage socket needs to be sealed while still offering removable access. This can be useful on access fittings, branch fittings, inspection points and pipe layouts where future cleaning or rodding may be needed.
Unlike a plain permanent blanking plug, a screwed access plug gives a removable cap. This makes it useful when the drainage layout needs to remain serviceable after installation.

160mm Access Plug with Screwed Cap
This 160mm access plug includes a screwed removable cap. The cap allows the drainage run to be accessed when inspection, cleaning or rodding is required. As a result, it is a useful fitting for drainage systems where future maintenance access matters.
The fitting should be installed so the screwed cap remains reachable after the drainage system is complete. Avoid placing the access plug where it will be permanently blocked by concrete, landscaping, chamber walls, other fittings or finished groundworks.
Before installation, make sure the socket is clean and free from debris. Also, check that the sealing area is in good condition before pushing the spigot end into place.
160mm Access Plug Installation Use
The 160mm access plug should be fitted into a compatible 160mm underground drainage socket. Use suitable pipe lubricant on ring seal joints where required by the system. This helps the fitting seat correctly and reduces the risk of damaging the seal during assembly.
When fitting, make sure the access plug is fully and squarely inserted into the socket. The screwed cap should be tightened securely, but it should still remain removable for future access.
Correct bedding and backfill are also important. The pipework and fittings should be supported evenly so the drainage system remains stable after installation. Poor support can place stress on joints and may affect long-term performance.
Access Plug for Maintenance Access
This 160mm access plug helps create a serviceable point in the drainage layout. If the pipe run needs checking, clearing or rodding, the screwed cap can be removed to provide access.
Access fittings should be planned carefully in underground drainage systems. Good access can make maintenance easier and reduce disruption if a blockage or inspection issue occurs later.
This product is not a chamber base. It is a removable access plug for compatible 160mm drainage sockets. If full chamber access is required, use a suitable inspection chamber or access chamber arrangement instead.
