Product Description
Copper tube for refrigeration and air conditioner are manufactured for refrigeration systems used in cold storage and air
conditioning units for residential and commercial buildings. It is supplied in in coils (copper pancake coil, LWC coil) and
straight lengths. Sizes are available from 3/16" to 4-1/8" (from 4.76mm to 104.78mm) in outside diameter. The copper
tubes are cleaned and capped, have a total residue maximum 0.038g/m².

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%
