About Us

Every cylinder is quality checked during the repair/manufacturing process and tested to the manufacturer's specifications before shipment. We repaire and recondition all brands of cylinders (welded and pneumatic construction) up to a 12" bore and 5" rod diameter, to include telescopic cylinders. Also, our hydraulic shop provides service "while you wait" for all hydraulic hose style requirements.

Adding certain equipment to include automatic CNC and HEM machines, special tooled engine lathes, large turret lathes and automatic equipment have our O.E.M. and manufacturing operational capabilities. We have manufactured cylinders up to an 8” bore, 4” rod diameter and 360” stroke
