LogiballDual Seal Inflatable Plug

SHARE
Logiball multisize dual-seal inflatable plugs are designed to isolate and test the annular space of dual-containment piping systems. Their donut-shaped profile allows them to easily slide between the carrier pipe and the containment pipe, making them the fastest and most cost-effective solution for low-pressure air testing. Once positioned between the two pipes, the plugs are inflated. This inflation causes the inner rubber wall to press firmly against the outer surface of the carrier pipe, while the outer rubber wall expands to create a tight seal against the inside of the containment pipe. Each unit includes two flow-through ports to insert and monitor the test medium (air) within the isolated annular space between the inflated plugs.
