About Astro Hydraulics

Astro Hydraulics, a division of Kundinger Service and Repair Solutions, specializes in the repair, replacement and manufacture of hydraulic and pneumatic cylinders regardless of make, model or size, including repair and replacement of hydraulic hoses, hydraulic pumps, valves, cylinders and seals.

Astro maintains a large inventory of steel tubing, hydraulic hoses, fittings and seals for prompt repair of both standard and metric components. Our skilled technicians build custom cylinders every day. We can fabricate parts as good or better than most original OEMs.

Astro Hydraulics was purchased by Jerry Wildenberg in 2012. Astro Hydraulics has been a family-owned company with both Jerry's wife and two children working there.

In 2024, Kundinger Service and Repair Solutions (KSRS) acquired Astro Hydraulics. An affiliate of Kundinger, Inc., a leading provider of fluid power, automation, and process control solutions across Wisconsin and Michigan, KSRS is also a family-owned and operated organization that is committed to serving its customers in northeast Wisconsin and beyond. Jerry Wildenberg stayed on the team as operations manager.
