Applications

Standard 1/4" SS-316 tubing are closed at one end, and have a laser drilled hole diameter which is precisely flow calibrated to the sizes and tolerances shown or to within your specific flow rates.

The precision hole is centered to within ± .125 mm and mechanically/optically round to tight Lenox Laser tolerances better than 2 micron.

Flow calibrated 1/4" tubing may be used on 1/4" fitting and valve components for critical flow orifices, gas/liquid separators, molecular beam masks, particle counters and many other mechanical purposes.

A Certificate of Calibration is not included with flow calibrated products. If a Certificate of Calibration is needed, please contact us.
