Total impact control for operational flexibility

The Hydra-Jar AP double-acting hydraulic drilling jar amplifies the force applied at surface in order to free stuck drillstring components during drilling or workover operations. It also offers the driller an important control option: to jar up, or down, with a force ranging from a light blow to an extra-heavy impact.
