IMH Precision Orifices are economical, reliable, highly accurate miniature flow restrictors. They are available for installation in both metal and plastic, and are 100% flow tested to ensure that every orifice is within ± 5% of its nominal flow rate. Tighter tolerances are available as specials.
IMH Precision Orifices are available in forward and reverse flow directions and in gas and liquid versions. Integral safety screens are incorporated where the orifice diameter is 0.5mm (.020") or below.
