Orifice flow restrictor
0.156" - 0.62" THE LEE COMPANY

Lee Company restrictors have become the accepted “standards” worldwide. Design engineers find their small size, light weight, and proven reliability are indispensable when the flow of fluids has to be controlled.

Our miniature precision flow restrictors are specified by manufacturers of aircraft hydraulic and fuel control systems, oil drilling equipment, missile controls, machine tools, and countless other products. Lee restrictors are a vital part of almost every military and commercial aircraft manufactured in the world. By employing already proven and qualified Lee restrictors in their designs, design engineers are using their own time and talents much more productively.

Lee offers a wide selection of single-stage or multi-stage orifices. Lee Jets, High Watt and Kilowatt Jets, and the Lee Microjet are all single orifice restrictors. Lee High Watt and Kilowatt Jets handle low Lohm rates (high flow rates) while higher Lohm rates (lower flow rates) are covered by Lee Jets.
