LEE IMH Calibrated Orifices
    The IMH Advantage
    Lee IMH Orifices are economical, reliable, highly accurate miniature restrictors. Available in stainless steel and brass models, these calibrated orifices are 100% flow tested in both flow directions to ensure that every part is within the specified flow tolerance. Flow tolerances as tight as ±2% are possible only if entrance and exit conditions of the orifice are closely controlled. This provides far more accuracy than orifices specified by hole size alone. An ordinary drilled hole held to a very tight tolerance will not result in a tight flow tolerance.
