The Lee Company”s IMH Insert Orifices are designed for liquid and gas applications where cartridge-style orifices are required. Available in 2.5 mm and 5.5 mm diameters, these new cartridge-style orifices are the smallest, self-retained flow restrictors available, providing far more accuracy than an ordinary drilled hole. Accuracy is confirmed by 100 percent flow testing to ensure that every orifice is within +/-5 percent of its nominal flowrate. Constructed entirely of stainless steel, the orifices are available in a range of flowrates, with orifice sizes as small as 0.002″ (.05 mm). Certain models are offered with an integral safety screen. Installation is aided by Lee’s controlled-expansion principle, which provides retention and creates a leak-tight seal to prevent bypass leakage.
