Why The Lee Company

The Undisputed Leader in Miniature Fluid Control

When you choose The Lee Company, you can trust that every component we make reflects our history, passion, and resolve to be your first choice for fluid control.

The Original Innovators


The Lee Company’s first-ever product was the Lee Plug®, a product developed to solve a specific customer problem. In the 70+ years that have followed this invention, we have continued to create and develop new, innovative, and groundbreaking products to solve customers’ problems.

We are the original inventor of dozens of unique miniature fluid control products and technologies that have been – and still are – found in everything from the cars and planes you use for transportation to the medical devices that help diagnose and treat illnesses. They are also performing critical functions in satellites thousands of miles away in outer space and in oil wells miles below the earth’s surface.

The Lee Company prides itself on solving our industry’s toughest problems. Thanks to our large global network of Technical Sales Engineers, we are able to work locally with our customers – taking the time to understand their issues and work through them as a team. We collaborate with each of our customers to identify what needs to be done, formulate a plan, and then come up with a solution that solves their problem and enables their success. Our passion for and experience with complex problem solving are why industry leaders have continuously relied on our engineering products and support for more than 75 years.
