The Lee Company is a leading supplier of miniature, precision fluid control products to a wide range of industries including medical devices and scientific equipment.

Lee Company products are recognized worldwide for superior quality, reliability and performance. Lee's unique capabilities in miniaturization and engineering expertise keep the company at the forefront of fluid control technology and identify Lee as a leading innovator in the field of fluid handling and control.

Founded in 1948, The Lee Company now has almost 800,000 sq. ft. of modern manufacturing and office space at four sites in Westbrook and Essex, Connecticut, and employs over 800 people.

The Lee Company is organized into nine product groups or “cells”.  Each product group is comprised of its own engineering, manufacturing and sales teams working together to provide better service and products.  Quicker responses and deliveries, higher quality, lower costs and product innovations to better solve our customers’ problems are direct benefits of this approach. 

The three Electro-Fluidic Systems (EFS) groups produce high quality miniature solenoid valves (general purpose and chemically inert models), high speed micro-dispense valves, atomizing and dispense nozzles, fixed and variable volume pumps, integrated fluidic manifolds, inert tubing and fluid control components and custom engineered designs.  These products are used in medical and scientific instrumentation, analytical/clinical chemistry, in vitro diagnostics, drug discovery and ink jet printing applications.

The five “aerospace” product groups supply Lee Plugs, high pressure solenoid valves, single and multi-orifice restrictors, nozzles, safety screens, check valves, relief valves, flow controls and shuttle valves to a wide range of industries including:

Medical Device Product Applications:

  • In-vitro diagnostics

  • Drug discovery

The Industrial MicroHydraulics (IMH) group supplies Lee Betaplugs, check and relief valves, flow controls, calibrated orifices, and other miniature fluid control components to the automotive and industrial markets.  IMH products meet the requirements for quality, economy and ease of automated installation, which are paramount importance to these industries.
