Applications
Refrigerant copper line set with flexible spiral waves is well designed and suitable for ductless mini-split air conditioner systems and VRF commercial air conditioner systems. The spiral waves make copper tubing more flexible and very easy to bend during installation. The refrigerant copper line set with spiral waves is constructed of seamless soft copper tubing, insulation tube, spiral waves and flaring nuts. The copper tubing is in C12200 (Cu-DHP) alloy, with copper content more than 99.90% and manufactured according to ASTM B280 standard. The spiral waves are on both sides of copper tubing, with length from 50cm to 150cm. And the copper tubing is flared and nut on each side of copper tube to make easy connection. Ink marking every foot in the insulation tube makes the size specification, standard and length distinguished easily. Our refrigerant copper line set with spiral waves is available from 10 feet to 50 feet.
Material
Copper Tube:
C12200 (Cu-DHP) alloy, with copper content more than 99.90% and with phosphorous range of 0.015% to 0.040%, conforms to ASTM B280 standard. The copper tube is fully annealed to the soft temper. All copper tubing end flared and nut and sealed to keep inside clean and dry.
Polyethylene foam insulation tube:
