USIPE patented HYHTBJ stuffing box and patented poly-nano-flexible composite particle stuffing float balls packing are changing the mechanism of sealing around the polished rod on the wellhead. It features a constant compression assembly to compress the stuffing float balls packing. The patented stuffing float balls packing replace the traditional stuffing cone packings and provide extended sealing cycle. The universal joint helps both horizontal and angular adjustments to centralize the polished rod and prevent the polished rod from side wear, which significantly extends the life of the polished rod and reduces the energy waste. The constant compression assembly and poly-nano-flexible composite particle stuffing float balls packing are the results of years of research and development by our technical team. The patented stuffing float balls packing has gone through thousands of field experiments and achieved polished rod protection, long term sealing, and energy saving.
