Capillary Tubing Gauge
Determining Cap Tube Size
The 12-A10971 cap tube gauge accurately measures a full range of capillary tube
sizes. Correct tube size is determined by using both the ID and OD dimensions. Check
OD of tube in "V" slot. Compare OD with reference chart printed on back of gauge to
determine probable ID. Use pin gauge to confirm actual size of ID. This same means of
cross referencing can be used whenever two standard ID’s are very close or OD’s are
the same.
MEASURES BOTH ID & OD
• Precision engineered.
• Stainless steel with black etched numbers
• Stainless steel wire plugs
• 12-A10971 includes cap tube file (12-A10972) and
protective vinyl carrying pouch.

Working With Capillary Tubing
Every precaution possible should be taken to prevent chips, dirt, flux, moisture,
filings, etc. from entering the system when changing the cap tube. Cap tube is
sealed and dehydrated from the factory. Remember, most cap tubes have very
small holes. It doesn’t take much to plug them. The 12-A10972 Cap Tube File
and 46-TCAP Cap Tube Cutter are specifically designed tools for working with
cap tube.
