The purpose of this 110mm soil socket plug is to cap off a section of the soil pipe system. It is often used as a temporary measure to protect a new section of pipe during construction works, but it can also be used to permanently cap off a pipe when a sanitary appliance (usually a WC) is removed. Access caps have a plain spigot end to enable them to be connected via push fit into the ring seal socket of another fitting or pipe as required.
