A restrictive tube used in a refrigeration system which restricts the flow of freon and allows pressure to build on one side and suction on the other. It is located between the condenser and the evaporator. ( 020)

Usually connected to an expansion valve or thermostatic switch; a hollow tube filled with a refrigerant to gauge or measure a remote temperature. The changes in temperature cause the refrigerant to expand or contract. That helps regulate or operate the valve or switch.

a tube of small internal diameter; holds liquid by capillary action

a thin copper tube of predetermined length into which the compressed liquid refrigerant is pumped

a very small diameter copper tube that serves to create a restriction in the loop

a small-diameter tube (metering device), whose bore and length are designed to permit the passage of a specific amount of liquid refrigerant or other liquid at a specific pressure drop

A long, narrow tube used to transmit internal gas pressure from a remote sensing bulb to a thermostatic expansion valve diaphragm.

A fixed-bore metering device. This is a small diameter tube that can vary in length from a few inches to several feet. The amount of refrigerant flow needed is predetermined and the length and diameter of the capillary tube is sized accordingly.

A tube sufficiently fine that capillary action is significant.

See Tube.

A metering device used to control the flow of refrigerant in a sealed system. It usually consists of several feet of tubing with a small inside diameter.

A small tube factory-placed into the air spacer of an insulating unit used for balancing interior and exterior pressures during transportation over higher elevations, i.e. mountain ranges or air transport.
