The PERMA-SET RETAINER PRODUCTION PACKER have the body lock ring and setting sleeve on the lower end of the packer and incorporate an oversized seal bore in the upper end. Because size limitations prevented conversion into the top set design, all the small size CT-FAB Packers remain bottom-set. Those older versions bottom-set packers that remain in the product line are covered in this unit.
The Model CT-FAB Retainer Production Packer in small sizes is equipped with a threaded bottom guide to accommodate various extensions. Available extensions include the Mill- out Extension and Seal Bore Extension.
