Features: 1?Compared with single-cone structure,the dual-cone and dual-cylinder structure allows higher hanging capacity for long heavy liner and more slip area which reduces the distortion and damage to upper casing and even higher setting success ratio. 2?The setting tool can be easily released just by applying certain weight on the drill string and rotating clockwise. 3?The Retrievable Pack-Off Bushing can be retrieved together with the setting tool after cementing,eliminating drill-out.
