Key Features of the 1/4" x 5/8" Mini Split Installation Kit
C12200 Copper Tubing for HVAC Applications
The refrigerant tubing uses high-purity C12200 copper designed for air-conditioning and refrigeration applications. The copper provides good thermal conductivity, corrosion resistance and formability for professional HVAC installation.
Factory Pre-Flared Ends
Copper pipe ends can be supplied pre-flared with flare nuts, reducing on-site preparation work and helping installers complete compatible mini split installations more efficiently.
White PE or Black Rubber Insulation
DABUND offers both white PE and black rubber insulation. Multiple insulation thicknesses are available to meet different climate conditions, local standards, installation environments and customer specifications.
Insulation Testing and Standards
Available insulation specifications include test requirements related to ASTM E84, UL 94, ASTM D1056 and ASTM G21. Copper tubing is designed to meet ASTM B280 requirements and uses C12200 copper material.
Complete Kit for Contractors and Distributors
Instead of purchasing the refrigerant line, drain hose, communication cable and wall accessories separately, buyers can source the major installation components together as one AC installation kit.

HVAC Pipe Insulation Performance
The closed-cell insulation surrounding the refrigerant tubing helps reduce heat transfer, control condensation and protect the copper pipe during installation and operation.
Black rubber insulation temperature range options from approximately -40°C to 120°C, depending on specification.
Closed-cell structure helps reduce moisture penetration and condensation.
Low thermal conductivity helps maintain refrigerant temperature.
Available UV-resistant insulation options improve protection in exposed installation areas.
Multiple insulation thicknesses are available for different applications and markets.
Thermal Insulation
The high-density closed-cell structure helps reduce heat transfer between the refrigerant piping and the surrounding environment, supporting efficient operation of compatible HVAC systems.
Condensation Control
Closed-cell insulation functions as both a thermal insulation layer and moisture barrier, helping reduce condensation on the suction line when correctly installed.
Flame-Retardant and Weather-Resistant Options
Flame-retardant and UV-resistant insulation options are available according to project requirements. Buyers can select insulation specifications based on the installation environment and applicable market standards.
50 Ft AC Installation Kit for HVAC Wholesalers and Suppliers
The 50 ft / 15.24 m configuration is intended for HVAC installations requiring a longer routing distance between compatible indoor and outdoor units. For wholesalers, distributors, HVAC brands and project suppliers, DABUND can provide bulk supply and customized installation-kit configurations.
Available customization includes copper pipe dimensions, insulation material and thickness, cable specifications, drainage accessories, logo printing, private-label cartons and complete installation-kit packaging.
Available AC Installation Kit Sizes

Is a 1/4" x 5/8" Line Set Compatible With My Mini Split?
A 1/4" x 5/8" refrigerant line combination is used by a range of mini split and HVAC systems, but pipe size cannot be selected by BTU or tonnage alone. Different HVAC manufacturers and models may specify different refrigerant line diameters even when the nominal capacity is similar.
Before purchasing this 50 ft AC installation kit, confirm the required 1/4" liquid line and 5/8" suction line in the equipment installation manual. Also check permitted line length, vertical separation, flare dimensions, insulation requirements and refrigerant charging instructions.
Installation, evacuation, pressure testing, refrigerant charging, flaring and brazing should be performed by qualified HVAC personnel in accordance with local regulations and the equipment manufacturer's instructions.
