The Pop-A-Plug P2 Heat Exchanger Tube Plugging System is the only mechanical tube plug that features both external and patented internally serrated rings designed to maintain a leak-tight seal under extreme thermal and pressure cycling.

Pop-A-Plug P2 Tube Plugging System reduces downtime, eliminates welding and explosives, and will not damage your tubes, tube joints or tubesheet.

Simple Installation – Prepare and size tubes using the brush and Go/No-Go gage supplied with kit, and install plug with hydraulic ram using shop air.

As the ram pulls the tapered pin through the ring, it expands into the tube, creating a leak tight seal.

When the proper force is reached, the breakaway “pops”.

This controlled force provides a consistent, repeatable installation each time by any installer, while protecting surrounding tubes and ligaments.
