    The Precision Micro-Orifices® are constructed of brass or stainless steel with orifice sizes from .0003" to .005" diameter. The orifices are used to accurately meter very low flow rates of gases or liquids. Optional stainless steel screens are available to protect the tiny orifices from minute contamination particles.
