Abstract
A wireline cleaning unit which replaces a conventional packing nut. A housing is sealed around a packing nut by O-rings to define an annular chamber between the housing and the exterior of the packing nut. Fluid communication between the longitudinal bore of the packing nut and the annular chamber is provided by radially extending bores through the packing nut. A line wiper disposed in the longitudinal bore of the packing nut wipes excess fluid off the line, the fluid then flowing down the longitudinal bore and through the radial drain ports into the annular chamber. The annular chamber in the outer housing is provided with a drain port and hose adapter for draining the collected fluid to a proper container.
