The flowstop expanding pipe stoppers are made of a rubber tyre ring, which is fitted between two plates. A moveable wing nut compresses the tyre, causing it to expand in the pipe which seals off the flow. Our flowstop expanding stoppers all meet current British Standard to ensure our customers receive a high quality pipe stopper.

We have been offering our expanding pipe stoppers to customers throughout the UK for many years. The flowstop expanding stoppers we offer at Pipe Equipment Specialists Ltd, are available in a range of materials such as nylon, aluminium or pressed steel. The flowstop expanding pipe stoppers we offer are designed to prevent the ingress of water and dirt into new and existing pipe work.Expanding stoppers, sometimes known as drain plugs or bungs, are used in pipes and duct work to help prevent the build up of water and dirt. They are suitable to be used in both new and existing pipe and duct work. Temporarily sealing the pipe using expanding stoppers makes it easy for repair and maintenance work to be carried out. There are a number of ways to repair drain leaks, however unless you are confident with handling waste plumbing leaks, it is recommended that you leave it to the experts to carry out a soil pipe repair. Failure to do the job properly could create a sizeable mess, and lead to further damage as well as significant expense.
