As technology demands precision and smaller tolerances, engineers are turning to Bird Precision micro-drilled inserts. These inserts are excellent for directly inserting into manifolds, valve bodies or instrument fittings. Sapphire and ruby orifices are swaged in place by a proprietary method for strength and sealing. Sapphire and ruby orifices are laser drilled and wire lapped. As a result, they are extremely round, sharp-edged and burr free. Bird Precision synthetic sapphire or ruby orifices feature zero porosity, high temperature tolerance and wear resistance, and are almost chemically inert. These orifices exhibit highly repeatable flows from less than 0.5 cc /min and offer the industry paradigm for strength and dependability.
