ABOUT Hercules OEM


In August 2017 and in an effort to better leverage synergies between the entire Hercules Fluid Power Group OEM Business sector we joined forces with the rest of the seal companies focused on servicing OEM customers to form the Hercules OEM. We will continue operating in each respective location only now as one company to better serve you!

The OEM sector was comprised of J Royal in North Carolina, RT Dygert in Minnesota and Chicago, High Performance Seals in Washington, All Seals in California and Texas, and Problem Solving Products or “PSP” in Colorado.


What does that mean for you?

  • We are excited to be merging our existing reputation of superior precision, quality, and expertise with excellent service and on-time delivery.
  • We are in the process of working to integrate a new operating system and phone system so that all five companies are on the same system for ease of communication between locations.
  • We have locations throughout the United States. Once we are all on the same operating system and phone system we can get parts to your door much faster.
  • Our supply chain grew so we now have access to even more suppliers to continue providing the best price in the marketplace along with the best quality products.

The Hercules OEM management team is as follows:

  • Jon Casten  President of Hercules OEM
  • Alonso Rhenals - Vice President of Sales and Marketing
  • Ginny LeBlanc  Director of Supply Chain
  • Brian Seil - Director of Engineering
  • Adam Stowers - Director of Quality and Technical Services 
  • Theresa Thompson Director of Finance

We could not be more excited about joining forces with the other OEM companies and we know that the Hercules OEM will be the most recognized name in the sealing industry. With the knowledge, experience, and resources that each company brings, the Hercules OEM will be a true force nationwide.
