About Us

Our best part is know how

Better than OEM parts, better than OEM knowledge – that's Hennco Waterjet Supply. Here's something else that's better; our prices. Hennco saves you 20-30% on every order compared to OEM.

If you know waterjets, you probably know our founder John Hennessey. He helped start the first waterjet aftermarket parts company in Minnesota. John understands waterjets like a pit crew understands their race car. Since 2000, John has worked side-by-side with the top waterjet engineers in the world, learning first-hand through R&D, launch and refinement everything there is to know about waterjet systems and waterjet cutting.

We welcome you to Hennco, and give you our word to do-more and know-more.

John Hennessey, President

Founded Hennco in 2018. John started in Waterjet in May of 2000 as the original employee at AccuStream. While with AccuStream John was responsible for sales and marketing until the company was sold in 2013 to Hypertherm. John worked at Hypertherm with the Waterjet Team until January 2018.

"My passion is helping waterjet customers. There is no better feeling than solving an issue with a customer to get them back up and running or giving them a tip to help them get more out of their equipment."

"I like seeing all the various types of waterjet equipment and how each manufacturer has developed their solution. In our aftermarket capacity we get to talk with end users and get feedback on these solutions. This feedback helps us understand how things perform and guides us in our efforts to improve waterjet technology."
