Static-Pac Shutdown Seals

High-Pressure Gas Contained

Conventional rod rings unload during shutdown, permitting high-pressure gases to escape. A Static-Pac assembly activates upon shutdown, mechanically wedging a lip seal tightly against the piston rod. The flexible polymer seal conforms to the rod circumference, locking in high-pressure gas.

When activating pressure is released during compressor start-up, the Static-Pac seal lifts off the rod surface to allow free movement of the rod.
