Expanding Foam Bridge

The Foam Bridge is a short cylinder of compressible, non-porous, inert foam mounted around a short length of flush threaded riser directly above the PrePak screen. The foam is compressed to fit in the drive casing during installation. When the drive casing is pulled back to expose the screen, the foam expands to seal against the bore hole to prevent debris from falling around the screen.
