1/2 in. x 3/4 in. x 100 ft. Insulated Copper Tube
DABUND 1/2 in. x 3/4 in. x 100 ft. Insulated Copper Tube is designed for compatible air-conditioning, refrigeration, heat-pump, mini split, VRF and central HVAC installations requiring this specific copper tube size combination.
The product uses 99.9% pure copper with ASTM B280 and C12200 DHP referenced in the source product information. Black Rubber insulation is the primary configuration shown on this page, while high-density closed-cell polyethylene foam is also available.
The 100 ft continuous length provides approximately 30.48 m of insulated refrigerant tubing for compatible projects requiring an extended piping route between HVAC components.
Quick Answer: This 100 ft 1/2 x 3/4 insulated copper tube combines ASTM B280 / C12200 DHP copper with factory-applied insulation for compatible HVAC and refrigeration systems. Final pipe-size suitability must be confirmed from the equipment manufacturer's technical requirements.

ASTM B280 and C12200 DHP Copper Tubing
The source product information identifies 99.9% pure copper and references ASTM B280 and C12200 DHP copper requirements for air-conditioning and refrigeration applications.
Copper provides thermal conductivity, corrosion resistance and installation flexibility for compatible HVAC refrigerant piping projects.
Appropriate HVAC cutting, bending and connection methods should be used to maintain tube geometry and reduce the risk of refrigerant-flow restriction.
1/2 in. x 3/4 in. HVAC Copper Tube Size
The product uses paired 1/2 in. and 3/4 in. copper tubing for compatible air-conditioning and refrigeration equipment.
Buyers should confirm that the selected HVAC equipment specifically requires this exact 1/2 in. + 3/4 in. tube combination before ordering.
The source product-family information does not provide a specific tonnage or BTU capacity mapping for 1/2 in. + 3/4 in. tubing. Equipment manufacturer specifications should therefore be used for final selection.
Black Rubber Insulation
Black Rubber insulation is the main configuration shown in the product images and wider insulated-copper-tube family table.
Factory-applied insulation helps limit unwanted thermal exchange and surface condensation around cold refrigerant tubing.
Closed-Cell Structure
The source describes a closed-cell insulation structure that provides both thermal insulation and moisture protection around the copper tubing.
Condensation Control
The insulation helps reduce surface condensation and moisture penetration around refrigerant piping during HVAC operation.
UV Resistance
UV-resistant insulation configurations are referenced for indoor and outdoor HVAC applications. Final suitability depends on the exact insulation material, thickness and exposure conditions.
Listed Temperature Range
The source page lists an insulation operating range of approximately -40°C to 120°C. Confirm this range for the exact configuration ordered.
Pressure Capability
The source page states that pressure capability can range from approximately 2100 PSI to 7000 PSI depending on the copper tube specification.
Actual allowable working pressure depends on tube diameter, wall thickness, operating temperature and exact product configuration. Confirm the applicable technical data before use with a specific HVAC or refrigeration system.

Black Rubber Insulation Detail
Black Rubber insulation provides a thermal and moisture-resistant layer around the copper tube and helps protect the refrigerant line during installation and operation.

100 ft Length for Extended HVAC Routes
The 100 ft continuous tubing length equals approximately 30.48 m and provides flexibility for compatible installations requiring an extended refrigerant piping route.
A continuous run can reduce unnecessary intermediate joints compared with connecting multiple shorter tubing sections.
The physical 100 ft length does not mean every HVAC system permits a 100 ft installed refrigerant run. Always confirm the equipment manufacturer's piping limitations.
Compatible HVAC and Refrigeration Applications
Compatible ductless mini split systems
Heat-pump installations
VRF systems requiring this pipe size
Central HVAC installations
Air-conditioning refrigerant lines
Compatible refrigeration systems
Residential and commercial HVAC projects
Final compatibility must be confirmed from the HVAC equipment manufacturer's required tube diameters, refrigerant type, design pressure and permitted piping length.
Important Checks for a 100 ft Refrigerant Run
Confirm Exact Copper Tube Sizes
Verify that the selected HVAC or refrigeration equipment specifically requires 1/2 in. and 3/4 in. copper refrigerant tubing.
Verify Maximum Permitted Piping Length
Confirm that the selected equipment permits the proposed 100 ft refrigerant piping route.
Check Maximum Elevation Difference
If indoor and outdoor equipment are installed at different elevations, verify the manufacturer's maximum permitted vertical separation.
Check Additional Refrigerant Charge
A 100 ft refrigerant run may require additional refrigerant beyond the equipment's factory charge. Follow the manufacturer's charging instructions for the actual installed piping length.
Check Equivalent Piping Length
Bends, fittings and elevation changes may affect equivalent piping length. Follow the equipment manufacturer's engineering limits rather than relying only on physical tube length.
Provide Proper Pipe Support
Use suitable HVAC-rated supports, clips or straps to reduce sagging, vibration and mechanical stress along the extended piping route.
Installation Guidelines
Plan the Complete Piping Route
Measure and plan the complete refrigerant route before uncoiling, cutting or modifying the tubing.
Avoid Sharp Bends and Kinks
Use appropriate HVAC tube-bending methods and suitable bend radii to reduce the risk of tube deformation or restricted refrigerant flow.
Protect the Insulation
Avoid crushing, cutting or leaving unnecessary gaps in the insulation around bends, supports and wall penetrations.
Keep Copper Ends Protected
Keep open copper ends capped or sealed during storage and installation to reduce moisture and contamination entering the refrigerant circuit.
Pressure Test and Evacuate Before Startup
Refrigerant piping should be pressure-tested, evacuated, charged and commissioned according to the HVAC equipment manufacturer's instructions and applicable local requirements.
