Plug underground sewage lines, water supply lines, and other pipe that’s hard to reach. These plugs attach to a 6-ft. extension pole with an adapter (both sold separately) so you can place them in confined spaces from a distance. Before placing them in your line, connect them to your air compressor with a hose to inflate them remotely. Also known as pneumatic plugs, they’ll seal wide and out-of-round pipe. Since they can lose pressure over time, they’re intended for temporary seals. Use them in lower-pressure applications than water-inflatable plugs.

Maximum air back pressure is the amount of pressure a plug can withstand without moving. Maximum water back pressure refers to the pressure resulting from the height of the water above the plug.

Adapters thread into a connector on the end of the plug. When installing the plug, adjust the adapter’s angle using the connector’s pull pin.

Poles snap into the adapter. For a longer reach, connect multiple poles together.
