1/2 in. x 3/4 in. x 100 ft. Insulated Copper Tube

1/2 in. x 3/4 in. x 100 ft. Insulated Copper Tube for HVAC and Mini Split Systems

DABUND PIPE has manufactured HVAC copper tubing, insulated copper line sets, mini split installation accessories and refrigeration copper pipe products since 2008. This 1/2 in. x 3/4 in. x 100 ft. insulated copper tube is designed for split air conditioning systems, ductless mini splits, heat pumps, VRF systems and central HVAC installations.

The copper tube is made from 99.9% pure copper and meets ASTM B280 and C12200 DHP copper standards. The black rubber insulation is UV resistant, flame resistant and suitable for working temperatures from -40℃ to 120℃, helping contractors reduce installation time while protecting the refrigerant line from condensation, heat loss and outdoor exposure.

Key Features of 1/2 in. x 3/4 in. x 100 ft. Insulated Copper Tube

The 1/2 in. x 3/4 in. size refers to the outside diameter of the copper tube. In metric dimensions, it is approximately 12.7 mm x 19.25 mm, making it a common copper line set size for larger mini split air conditioners and HVACR systems.

The copper pipe uses 99.9% pure copper and complies with ASTM B280 and C12200 requirements for air conditioning and refrigeration applications. It is suitable for refrigerant lines, heat pump systems, mini split line sets and HVAC installation projects.

Available AC copper tube sizes include 1/4 in., 3/8 in., 1/2 in., 5/8 in., 3/4 in., 7/8 in. and 1 1/8 in. Common roll lengths include 15 m, 20 m, 25 m, 30 m and 50 m. Custom sizes, insulation thicknesses and packaging can be produced for wholesale and OEM orders.

The insulation can be made from black rubber or high-density closed-cell polyethylene foam. It is UV resistant and designed to meet ASTM E84, UL94, ASTM D1056 and ASTM G21 requirements. The operating temperature range is from -40℃ to 120℃.

This insulated copper tubing works for air conditioning and refrigeration applications including ductless mini splits, heat pumps, VRF systems, centralized air ducted units and residential or commercial HVAC installation projects.

The pressure rating can reach approximately 2100 PSI to 7000 PSI depending on tube specification, which is much higher than the typical pressure requirement for R410A air conditioning systems.

DABUND PIPE produces insulation in-house and supports OEM printing on the insulation surface, including company name, logo, size, length, meters, refrigerant direction marks and other customized information.

Features of Pipe Insulation Tubing

The pipe insulation is made for HVAC copper tubing and refrigeration copper lines. It provides stable insulation performance across a temperature range from -40℃ to 120℃.

The closed-cell insulation structure helps reduce condensation on the copper tube surface. The insulation material works as both an insulation layer and a moisture-proof layer, reducing the need for an additional water vapor permeation protective layer.

The insulation protects the copper pipe from heat loss, moisture, UV exposure and mechanical damage during installation and long-term use.

Advantages of Black Rubber Insulated Copper Tube

Excellent Heat Preservation: The high-density closed-cell structure offers low thermal conductivity and stable temperature performance. It helps protect the copper refrigerant line even when outdoor temperatures are low.

Eco-Friendly Material: The insulation material is designed to be low odor, non-irritating and resistant to mold growth. It also helps improve corrosion resistance and extend the service life of the copper tube.

Flame Retardant Performance: The insulation material is formulated for flame resistance and is suitable for HVAC installation environments requiring ASTM E84, UL94 or similar fire performance standards.

Moisture Condensation Control: The insulation layer reduces condensation on the refrigerant line, helping keep the installation area cleaner and reducing the risk of moisture-related damage.

Clean and Professional Installation: Pre-insulated copper tube makes HVAC installation faster, cleaner and more reliable for contractors, wholesalers and air conditioning system installers.
