The ACE jar tester is the most versatile jar press on the market. It has the ability to do drilling and fishing jars of all sizes on the same platform. The robust and modular design make it easy to save space and work safely. A complete stand alone unit can be ordered which includes the skids, cylinder assemblies, and control console. All TorsionMaster breakout units already have a jar tester control port. The customer can also order the skid and cylinder assembly to utilize an existing breakout unit console. The SAE hydraulic fittings, hoses, and seals are easily serviced and replaced if necessary. Operation and preventative maintenance training are available at the ACE facility.
