(4) Its external diameter is much smaller than that of the ordinary lifter, which increases the oil area.
(5) It reduces the up and down resistance of sucker rod, saving the electricity.
(6) It is anti-corrosion and anti-alkali.
(7) It protects the sucker rod and tubing, and extends the operation cycle.
