Unique Products for the Underground Utility Professional
Disc Stoppers are an easy and economical way to stop gas flow and plug abandoned lines up to 4" in diameter. These tools are constructed of a steel shaft with reverse male threads and four heavy-duty rubber washers to provide a seal. Push or pull to insert and remove into a pipe using the special T-Handle wrench. To leave it in the pipe remotely, loosen the wrench to detach it from the stopper.
