Copper Capillary Tube for Refrigeration and Air Conditioning

Copper Capillary Tube for Refrigeration and Air Conditioning

Product Description

Copper capillary tube is one of the most commonly used throttling devices in the refrigeration and air conditioning systems (domestic refrigerators, deep freezers, water coolers and air conditioners). The copper capillary tube limits the maximum amount of the refrigerant that can be charged in the refrigeration and air conditioning system due to which the receiver is not required in these systems.

Copper capillary pipe is usually manufactured with fine precision. This precision allows airflow to be smoother, more uniform, and more closely monitored, making such applications as fluid & air restrictors much more useful.

Copper capillary tubing is usually supplied in coils (level wound coil and pancake coil) and in annealed form. Our copper capillary tubing is available in outside diameter from 1.83mm to 6.1mm (from 0.072” to 0.240”)

 

Material

The copper tubes are made in compliance with UNS C12200 (Cu-DHP) alloy, with copper content more than 99.90% and with phosphorous range of 0.015% to 0.040%
