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 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.
These Disc Stoppers are pushed into the pipe with a T-Handle wrench. Internal cleaning or deburring is not necessary. The Disc Stopper washers are designed to create a flexible sealing wedge inside the pipe. After pushing the Disc Stopper into place, the Stopper is detached by unscrewing it from the wrench. Allowing the end of the pipe to be repaired. Once work is complete the Disc Stopper can be retrieved using the wrench.
