Inflatable Blocking Plugs

Available76 products
Inflatable blocking plugs have a rubber bladder that inserts into a pipeline and fills with fluid to provide a temporary plug. They fit into out-of-round pipes that have lost their shape due to wear or damage. Blocking plugs are primarily used in drain, waste, and vent (DWV) systems for maintenance and pressure testing of water systems.
