Lee Plugs are the most successful method to seal drilled holes for critical applications. Over 100 million are in use where permanent leak-proof seals are required.


Lee Restrictors feature small size, precision performance and long life. Single orifice and multi-orifice models cover a wide range of restriction and can be customized to meet special requirements.



Lee Flow Controls including restrictor check valves, directional flow controls and constant flow valves are available in a wide range of sizes to suit many applications.



Lee Nozzles can produce either a hollow cone of atomized spray as in our Spin Jet or an accurately targeted jet of lubrication fluid.



Lee Cheks are the smallest insert check valves available anywhere in the world. One model is only an eighth of an inch in diameter and slightly over an inch long.



Lee Relief Valves provide safety relief, linear, or high pressure operation. Four sizes, three styles and a hundred cracking pressures cover a wide range of applications.





Lee Shuttle Valves are offered in four configurations: spring biased with the emergency port normally closed; Detented where the poppet latches to close off either the emergency port or the normal port; selective shuttle valves with a non-biased loose ball design; and the inverse shuttle valves where the lower pressure inlet port is open to common instead of the higher pressure inlet port.



Lee Safety Screens protect hydraulic components from contamination. We offer a wide variety of both intermediate and high pressure etched screens, and high pressure HI-BAR screens with working pressure capability when fully clogged of over 7500 psid. Lee Safety Screens can be customized to meet special requirements.



Lee Piloting Solenoid Valves are designed for use in aerospace hydraulic and fuel systems, oil tool applications, and other challenging high pressure applications. Incorporating innovative design and advanced technology it has set a new bench mark in space and weight savings, and power consumption.



Lee Line Mounts are regular Lee valves and restrictors fitted with compact threaded connections for hoses or manifolds. Connection systems include MS33514, AS4395, MIL-F-85720/1 and Ring Locked adapters.



Lee Pressure Components include miniature restrictors for damping pressure transients, adjustable pulsation dampers, and miniature passive peak pressure recorders.
