Key Specifications

Key Features of the 1/4" x 3/8" HVAC Installation Kit

C12200 Copper Tubing for HVACR Applications

The refrigerant line uses C12200 DHP copper tubing designed for air-conditioning and refrigeration applications. The copper tubing is manufactured for ASTM B280 requirements according to the ordered specification.

Pre-Flared Copper Tube Ends

Both copper tube ends can be supplied pre-flared with flare nuts. This reduces preparation work during compatible mini split installation and helps HVAC installers complete connections more efficiently.

White PE and Black Rubber Insulation Options

DABUND provides both white polyethylene insulation and black rubber insulation. Multiple insulation thicknesses are available to meet different climate conditions, market specifications and HVAC installation requirements.

Insulation Testing Options

Available insulation specifications include testing related to ASTM E84, UL 94, ASTM D1056 and ASTM G21. Buyers can confirm the required insulation material, thickness and testing standard before placing an order.

Complete Installation Kit Configuration

Instead of purchasing the refrigerant line, communication cable, drain hose and wall accessories separately, HVAC distributors and installers can source the primary components together as one mini split installation kit.

High-Purity Copper Tubing

White PE Insulated Pipe

Copper Flare Nuts

Three-Layer PE Insulation Structure

The white PE insulated line set uses a multi-layer structure designed to protect the refrigerant piping and reduce heat transfer. The combination of embossed polyethylene film, closed-cell foam and inner insulation helps provide thermal insulation, moisture resistance and mechanical protection.

Insulated Pipe Warehouse

Inner Insulation Layer

Outer Protective Layer

The embossed PE outer layer is designed to improve wear resistance and provide additional protection for the insulated copper tubing. UV-resistant material options are available according to customer requirements.

Middle IXPE Foam Layer

The middle closed-cell IXPE foam layer helps reduce heat transfer, resist moisture penetration and absorb external impact during transportation and installation.

Closed-Cell Inner Layer

The closed-cell inner insulation structure helps improve thermal performance and moisture resistance around the refrigerant tubing. Available insulation specifications can support operating environments from approximately -40°C to 120°C depending on material configuration.

10 Ft HVAC Installation Kit for Wholesalers and Distributors

DABUND supplies the 10 ft 1/4" x 3/8" HVAC installation kit for B2B customers including HVAC wholesalers, importers, distributors, contractors and private-label air-conditioning brands.

The complete-kit approach helps buyers standardize product specifications and packaging while reducing the number of separate HVAC accessories that must be sourced from different suppliers.

OEM and ODM options can include customized copper line sizes, kit length, insulation thickness, printed insulation, communication cable, drain hose, wall accessories and private-label packaging.

Available HVAC Installation Kit Sizes

In addition to the 1/4" + 3/8" line set, DABUND manufactures multiple copper tube combinations, insulation thicknesses and kit lengths for different mini split and HVAC applications.

Is a 1/4" x 3/8" Line Set Right for My Mini Split?

A 1/4" liquid line combined with a 3/8" suction line is commonly specified for some smaller-capacity mini split air-conditioning systems. However, refrigerant line dimensions are determined by the specific HVAC manufacturer and model rather than BTU capacity alone.

Before purchasing the kit, confirm that your equipment requires a 1/4" liquid line and 3/8" suction line. Also check the manufacturer's requirements for maximum line length, vertical separation, flare dimensions, insulation thickness and additional refrigerant charge.

Some 9,000 BTU and 12,000 BTU mini split systems may use a 1/4" x 3/8" line set, but compatibility must always be confirmed against the installation manual for the specific indoor and outdoor unit combination.

Refrigerant piping, evacuation, pressure testing, electrical wiring and refrigerant charging should be completed by qualified HVAC personnel in accordance with local regulations and the equipment manufacturer's instructions.
