Product Name:Copper Capillary Tube
Description:

Copper capillary tubes aresmall diameter tubes. They are used by the air conditioning and refrigerationindustry to increase the pressure of the refrigerant gas in the condensing unit.Copper capillary tubes with uniform internal diameter forms the metering devicein refrigeration and air-conditioning systems. These control the flow ofrefrigerant gases in the system.

Our copper capillary tube isused throughout the refrigeration and air conditioning industry for restrictionapplications. The tube is produced in C12200 (Cu-DHP) alloy to the hard drawn,light

drawn, light annealed and softannealed temper. Our copper capillary tubes are manufactured in strict adherence to AmericanStandard – ASTM B360 and European Standard – EN 12450.
