INSERT SEAL
The insertion seal is an integrated unit whose seal assembly is sealed with the inner hole of the SPF grit packer. The bottom positioning indicator provides the positioning indication of the intubation and SPF grit packer. When it is necessary to take out the intubation or confirm the intubation position, lift the oil pipe and provide 5T axial load to make the elastic claw of the positioning indicator retract under the action of the chamfer at the bottom of the packer, so as to take out the sealed intubation.
Note: Other specification products are available.
