Cylindrical Stoppers

Cylindrical Stoppers are inflatable Pipe Plugs with a rugged waterproof cover that when inflated to the proper internal pressure can hold as much as 10 lbs. of pressure in the pipe. The broad central zone makes contact with the wall of the pipe and holds against higher pressures than other types of bag Pipe Plugs.

Cylindrical Stoppers should be inflated to the pressure indicated on the direction card fastened to each Pipe Plug or indicated in the table below. Use a gauge and monitor the inflation pressure. These inflation pressures leave a margin of safety. Cylindrical Stoppers when inflated according to these directions will hold against pipe pressures equal to 60% of the pressure in the bag. A 6” Stopper for example, when inflated properly to 15 psi, will hold back about 10 psi in the main.
