Capillary tubing is usually manufactured with fine precision, down
to one thousandth of an inch. This precision allows airflow to be
smoother, more uniform, and more closely monitored, making such
applications as fluid & air restrictors much more useful.
Capillary tubing has very small inside diameters (e.g. .**6 to .**5
inches). Capillary tubing is usually supplied in coils and, apart
from exceptions,it comes in annealed form.
Standard: ASTM B**0
