Another innovative breakthrough for serving the industry

The JN Series of hydraulic wrench was specifically designed to quickly, safely, and accurately tighten or loosen gas compressor piston rod crosshead jam nuts; however, the tool can be adapted to turn any nut affected by an obstruction through its center. The JN Series is distinguished by its patented “split-head” design that enables the tool to fit over any pipe or rod and around the nut to be turned. Capacities range from 100 to 38,000+ foot-pounds of torque using a standard bidirectional 10,000 psi hydraulic pump.

Fast

The PATENTED “Split Head” design can be placed around the wash pipe, piston rod or any other type of shaft, rod, pipe or tube and on the nut or adapter in less than one minute. Accurate tightening or loosening of the nut is easily achieved in just a few seconds.

Safe

The JN-Series hydraulic wrench eliminates unsafe hammer wrenches, hydraulic jacks or cranes, and other unsafe equipment currently being used to turn these nuts.

This fast hydraulic wrench, originally designed specifically to deal with Crosshead Jam Nuts, provides accuracy to ± 3% with the use of a standard advance hold and retract 10,000 p.s.i. air powered hydraulic pump

Functional

The JN-Series hydraulic wrench will work equally well in compressor crosshead access ports or any nut that has a shaft, rod or tube running through the middle of it. It will work right-side up or upside-down, sideways, etc…for both loosening and tightening.

Made of TL T-6 durable, highength, lightweight aircraft alloy with the same sturdy, dependable and accurate design (as steel cylinder).

Reaction Pad

Reacts against the Compressor crosshead structure or any other solid and flat surface.

Coated
