1/4 in. Liquid Line and 3/8 in. Suction Line

The refrigerant line set combines a 1/4 in. liquid line with a 3/8 in. suction return line.

Both tube sizes should match the refrigerant piping dimensions specified by the mini split or heat-pump manufacturer. Do not select the installation kit based only on nominal system capacity.

Factory-Flared Copper Tube Ends with Nuts

Both ends of the copper tubing are supplied with factory-prepared flare connections and nuts.

Pre-flared connections can reduce field preparation work during compatible mini split installation. Final connection dimensions, flare condition and tightening requirements should always be checked against the HVAC equipment manufacturer's installation instructions.

Pre-Insulated Copper Refrigerant Tubing

The kit includes factory-insulated copper tubing to help reduce unwanted thermal exchange and condensation along the refrigerant piping.

The featured product configuration uses White PE insulation. The source product information also lists Black Rubber as an available insulation option for suitable orders.

White PE insulation thickness options listed by DABUND include 8 mm, 9 mm, 10 mm, 13 mm, 19 mm and 25.4 mm. Black Rubber insulation is also available in selected thicknesses.

For the 1/4 x 3/8 configuration, the DABUND product family lists 0.75–1.0 ton and 9,000–12,000 BTU as general references. Actual compatibility must be confirmed from the refrigerant line dimensions specified by the HVAC equipment manufacturer.

Installation Guidelines

Confirm the Required Line Set Size

Verify that the HVAC equipment specifically requires a 1/4 in. liquid line and 3/8 in. suction line before installation.

Confirm the 10 ft Length

Measure the complete route between the indoor and outdoor units before ordering to confirm that the 10 ft line set provides sufficient installation length.

Protect the Factory Flare Connections

Inspect the flare surfaces and nuts before connection and follow the HVAC equipment manufacturer's specified tightening method and torque requirements.

Avoid Sharp Bends and Kinks

Route the copper tubing using appropriate bend radii to reduce the risk of kinking or restricting refrigerant flow.

Protect the Insulation at Wall Penetrations

Use the appropriate wall pipe, sleeve or protective components where the line set passes through the building structure to reduce abrasion and insulation damage.

Route the Drain Hose Correctly

Where gravity drainage is used, route the condensate hose with an appropriate downward slope and avoid kinks that could restrict water flow.

Follow the HVAC Equipment Manufacturer's Instructions

Refrigerant piping, electrical connections, evacuation, charging, condensate drainage and system commissioning should follow the equipment manufacturer's instructions and applicable installation requirements.
