Also known as pneumatic plugs, these plugs conform to wide and out-of-round pipes.

These extra-long plugs allow you to seal off two pipes at the same time. They have two separate inflation chambers to release back pressure gradually and prevent splash back as water clears the drain line.

Use these rugged rubber lifting bags under heavy loads with less than 1" of clearance, on soft surfaces, and under water.

Charge these accumulators to the pressure you need.
