Flare End Insulated Copper Tube

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.

Material

Copper Tubing:

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, EN 12735-1, AS 1571, JIS H3300 standard. The copper tube is fully annealed to the soft temper. R410a & R32 grade.

Polyethylene foam insulation tube:

Light weight and low-density cross-linked polyethylene foam, tear resistant, designed for insulating cooling and heating lines. Conforms to ASTM E84 (25/50), UL 723, UL 94 standard, AS 1530.3 standard, EN 13501-1 standard with thermal conductivity (K value) 0.263 Btu•in/ft2•h•F (0.038 W/m•K) at mean temperature 104°F (40°C)

Color: embossed White / embossed black / embossed grey

Thickness: 3/8”, 1/2” (8mm, 9mm, 10mm, 13mm)

Elastomeric insulation tube:

Flexible and closed cell elastomeric material designed for insulating cooling and heating lines. Conforms to ASTM C534, ASTM E84 (25/50) standard, with thermal conductivity (K value) 0.25Btu•in/ft2•h•F (0.036 W/m•K) at mean temperature 75°F (24°C)

Color: Black, Red, Blue, Green

Thickness: 1/4”, 3/8”, 1/2” (6mm, 9mm, 10mm, 13mm)

Nuts: 45° forged brass nuts
