Application 0
The inserts can be used with a wide variety of fittings by accurately machining the inside of the fitting. The orifice is then pressed into the fitting for control of the flow rate of liquids or gases. Manifolds or other custom assemblies that require flow rate control of fluids can be accurately machined to press fit the orifices.
