Adjustable Offset Rod Seal
價格：元
The Adjustable Offset Rod Seal is a wellhead sealing device developed by our company, based on the conventional rod seal. It features a ball-type universal offset adjustment mechanism. This simple structure offers low failure rates and excellent sealing performance. It can automatically adjust the angle during the reciprocating movement of the pumping unit, preventing the wellhead's tilt from causing eccentric wear and damage to the rod and blowout preventer box.
