Applications:
Flare end insulated copper tube is suitable for ductless mini-split air conditioner systems, VRF commercial air conditioner systems,
AC & heat pump. It is with flaring and nuts on each end of copper tube to make easy connection. The flare end insulated copper tube
mainly supplied in pair (twin) copper coils. The copper tubes are manufactured according to ASTM B280 standard (EN 12735-1 standard
or AS 1571 standard). Ink marking every meter in the insulation tube makes the size specification, standard and length distinguished easily.
Our flare end insulated copper tube is available up to 30 meters.
