Precision Microhydraulics

Lee Components solve the critical problems of size and weight

The Lee Company, for over 50 years the only authority in Microhydraulics. Components from less than 0.01 in up to 1.0 in diameter, and from 0.1 to 28 grams. We help designers achieve the size and weight reduction they need, with operating pressures to 8,000 psi. We also take the time for 100% inspection and testing. This kind of care results in the high reliability and long life for which Lee components are noted.

The Innovation Never Stops

New ideas and new products are a way of life at The Lee Company. Whether it's in aircraft, machine tools, or oil tool equipment. No company is better suited to provide you with the right standard or special components than Lee. Select from thousands of proven Lee designs. And to help you, we offer the Lee Technical Hydraulic Handbook with complete Microhydraulic engineering reference.

Special Products

Special Products

The Lee Company offers many miniature flow control components other than the standard products detailed above.
In fact, approximately 50% of all Lee products are special or custom items designed to meet the requirements of a specific application.
The majority of these special products are minor variations of standard products and may differ only slightly in: lohm rate, cracking pressure, leakage, flow testing, materials etc.
The remainder are uniquely different from the 'standards' described above and include:
Special Products
Threaded HI-BAR Lee Plugs
Air assisted atomising nozzles
Gas turbine engine fuel nozzles
Transmission/gearbox lubrication nozzles
Eductors or 'jet pumps'
Higher temperature and higher flow and check valves
Zero-leak relief valves
Bypass valves
Flow fuses and vapour vent valves
Mechanically actuated and indicating valves
Absolute upstream pressure regulators (pneumatic)
HI-BAR safety screens of almost any configuration
Higher temperature and higher flow solenoid valves

The Lee Company sales and engineering staff are eager to help you in solving your fluid control problems with special products that fill your needs.
