Cased Hole Packoff
This unit it designed to wipe wire free of well fluids and debris. This task is accomplished by the use of replaceable rubber inserts that “Squeeze” around the wireline as it is drawn through the packoff body.
Unit will affect a seal at 5,000 psi. Working pressure (static line). Seal is maintained by hydraulic pressure supplied by a 3,000 psi hand pump.
Unit may also be used as a “Dual Packoff”. This is the configuration most preferred, simply because it allows you to use the lower unit as your “Line Wiper” and the upper unit as your “Packoff” (static line).
