The Lee Company”s 303 IMH Orifice stainless steel miniature flow restrictor is 100 percent flow tested to ensure that every part is within +/-5 percent of its nominal flowrate. Because the entrance and exit conditions of the orifice are closely controlled, the orifice provides more accuracy than an orifice specified by hole tolerance. Specifically designed for installation into plastics in medical applications, the orifice features a unique, barbed design that provides easy “press-in” installation, ensures retention, and prevents any bypass leakage around the orifice.
