Industrial Microhydraulics
    In 1991, The Lee Company founded the Industrial Microhydraulics (IMH) Division to adapt its proven design concepts to meet the higher volume production, performance and cost requirements of automotive and industrial hydraulic and medical applications. Using design techniques similar to those used for the Lee Plugs, valves, restrictors and safety screens that have logged millions of flight hours in aerospace applications, The IMH Division can now offer products of the same reliability and consistent performance, in very high quantities. The Lee Company continues to expand the product offerings in The IMH Division. Should you need a product not shown in this website, please contact a Lee Sales Engineer to discuss your specific requirements.

Betaplugs are pre-assembled, one-piece, tapered expansion plugs specifically engineered to seal fluid passages in metal castings and plastic housings leak-tight, without the use of threads or sealants.
IMH Orifices are economical, reliable, highly accurate miniature flow restrictors for installation in metal or plastic housings.
IMH Check Valves are threadless, cartridge-style valves designed for simple, low cost installation into metal or plastic housings. They are based on the same hard seat Lee ChekŪ designs used in flight control systems on almost every aircraft flying today.
IMH Shuttle Valves feature a compact, non-detented, selective design, and are an economical and reliable solution to the problem of hydraulic isolation in manifolds.
IMH Screens Lee IMH Screens are miniature "last chance" safety screens designed to protect critical fluid control components against rogue contamination.
