Z Type Hydraulic Jars

The Logan Z Type Hydraulic Jar is used for light drilling, fishing, coring, reaming, testing, side tracking, and washover operations. This straight-pull jar combines the principles of mechanics and hydraulics in a simple to assemble, easy to operate design. The jar has a closed hydraulic system that contains the hydraulic fluid within the jar and well fluids cannot enter the tool. The internal working parts are constantly lubricated by the hydraulic fluid within the tool resulting in long wear life of the parts.
