Mechanical Blocking Plugs
Mechanical blocking plugs provide a seal inside or at the end of a pipe to block flow and allow for pressure testing, maintenance, or to prevent unwanted material from entering the pipeline. A manual closure mechanism squeezes two plates together to compress and expand a rubber seal that presses against the internal walls of the pipe. They are primarily used in drain, waste, and vent (DWV) systems.
