Mission Critical Applications in Aerospace Systems

Precisely regulate fuel flow to optimize engine efficiency. Properly lubricate gears and bearings to increase system life and reduce maintenance. Accurately control the extension and retraction of actuators. Safely generate and store hydraulic pressure. Avoid issues associated with reverse flow, excessive pressure transients, thermal expansion, or cavitation. Protect components from debris and contamination. Reduce or eliminate leakage. Lee products are engineered to help you accomplish these goals in the smallest, lightest, and most reliable package available.
