Model B Non-Locating Tubing Seal Unit
Intended for use as the lower seal assembly in multiple packer installations. With sufficient seal units mis-measurement or tubing movement can be accommodated. Production tubes, tailpipe and other accessories can be added below.
Spacer Sub Seal Units

Add-on Seal Units
Are used to add additional seal stacks to Model “C” Locator Tubing Seal units and Model “B” Tubing Seal Units. Any number may be used to accommodate expected tubing movement. With these, two sets of seals will always be in the packer seal bore.
