This is a hydraulic jar, with the characteristics of compact structure, reliable seal, high strength and optimum up jarring effect. It is the first selected tool in fishing operation in the case of freeing the sticking point by up jarring. When used with jar intensifier type YJQ, a remarkable jarring effect can be obtained.
