Description
Standard 3/8″ SS-316 tubing are closed at one end, and have a laser drilled hole diameter.
The standard orifices may be used in 3/8″ fittings and valve components as critical flow orifices, flow restriction, gas/liquid separators, molecular beam masks, flow restrictors, particle counters and many other purposes.
Optically measured holes are not guaranteed to meet a specified flow rate.
