hydril GK 13 5/8 5M annular BOP and packing element

Packing Unit-Nitrile(NBR)1003263-02 13 5/8" 5M Annular BOP Seal Kit 1002209

The heart of the GK blowout preventer is the packing unit, manufactured by Tianjin Dongrui Petroleum Machinery Co., Ltd. The unit is made from quality proprietary rubber compounds reinforced with flanged steel segments. It has a large volume of tough, feedable rubber to meet any requirement. I can produce the 100%exchanged with Rongsheng and Shenkai GK annular BOP packing element.

The molded-in steel segments with flanges at the top and bottom anchor the packing unit within the blowout preventer, controlling rubber extrusion and flow when sealing off well pressures. The confined rubber under compression resists tears and abrasion.

All annular blowout preventer packing units are subjected to wear during closure and stripping. The design of the HYDRIL GK compact blowout preventer ensures closure wear on the outside of the packing unit and stripping wear on the inside, affecting the stripping life of the unit due to routine closures.
