The low-cost, lightweight Hydra-Stopper Line Stop Machine isolates a section of pressurized pipe for repair, maintenance, or replacement of valves and hydrants in minutes — eliminating system shutdowns and saving time and money. Temporarily plugging a pressurized pipe with the Hydra-Stopper, combined with the HSF 250 Line Stop Fitting, starts with a single tap to allow the under-pressure insertion of the device. After completion of the work, remove the line stop machine and attach a completion plug.
