The Expendable Seating Sub is designed to temporarily plug the tubing below a hydraulic packer by dropping a ball down the tubing into a seat. The seat is designed to shear out given pressure, depending on the number of shear - pins used. Our Model JHM is a Half Shoe Guide made at the bottom to allows easy re-entry and pasage of wireline tools during wireline operation bellow the sub.
