The Lee Company, a leading innovator in precision fluid control technology, introduces new, miniature, calibrated IMH Insert Orifices for both liquids and gases. At 2.5mm (0.10") in diameter x 3.3mm (0.13") long, these new cartridge-style orifices are the smallest, self-retained flow restrictors available, and are designed to provide far more accuracy than an ordinary drilled hole.

Accuracy is confirmed by 100% flow testing to ensure that every orifice is within ± 5% of its nominal flow rate. Constructed entirely of stainless steel, the new IMH Insert Orifices are available in a range of flow rates, with orifice sizes as small as 0.002" (.05mm). Certain models are offered with an integral safety screen. Installation is simple using Lee's proven controlled expansion principle, which provides retention and creates a leak-tight seal that prevents bypass leakage.
