The GMQ-32-P3-M2-S Polished Rod Sealer can automatically adjust to the lateral movement and misalignment of the polished rod while maintaining reliable sealing performance. This design helps eliminate lateral support force, ensures more uniform stress on the packing, and solves the problem of one-sided wear caused by rod deviation.

By reducing friction between the polished rod and the packing, the sealer helps extend packing service life, reduce the frequency of tightening and replacement, lower maintenance workload, prevent crude oil leakage, reduce environmental pollution, and decrease pumping well energy consumption.
