Product Description

We designed every aspect of this double-acting hydraulic jar to withstand the rigors and long hours of challenging applications. Featuring an extra-long stroke length for exceptional impact and impulse forces during jarring operations, the Double-Acting Fully Hydraulic Drilling Jar  offers infinitely variable trip loads up to the maximum rating of the tool. Only a minimal load is required in both the up and down jarring directions, which is crucial in directional, horizontal, and extended-reach wellbores. This makes the jar an ideal solution for modern drilling operations.
