Shock Subs
BlackGold shock subs are used for reducing vibrations and keeping the drill bit firmly on the bottom to reduce drill string connection fatigue and prolong drill string life.
Hydraulic Shock Sub Type YJ
This hydraulic shock sub is fully hydraulic and is used for reducing vibrations caused by hard formation drilling and keeping the drill bit firmly on the bottom, so that it helps to reduce drill string connection fatigue and prolong drill string life.

Mechanical Hydraulic Shock Sub Type DHJ
This mechanical hydraulic shock sub is a new type two-function shock sub that absorbs the pulsation and shock from drill tools by compressing spring and SI oil to store the energy. It is used for reducing vibrations caused by hard formation drilling and keeping the drill bit firmly on the bottom, so that it helps to reduce drill string connection fatigue and prolong drill string life.
