capillary tube

[′kap·ə‚ler·ē ‚tüb]
(engineering)
A tube sufficiently fine so that capillary attraction of a liquid into the tube is significant.

capillary tube

A tube of small internal diameter; used in refrigeration as a control for the flow of liquid refrigerant, or as an expansion device between the condenser and evaporator; or used to transmit pressure from the sensitive bulb of a temperature control to the operating element.
