Daikin LS38343825 Line Set 3/8 X 3/4 X 3/8 Inch 25 Foot

Product Description

The DAIKIN LS38343825 is a pre-flared, insulated refrigerant line set designed to connect the indoor air handler to the outdoor condensing unit in a mini split system. The set includes a 3/8-inch liquid line and a 3/4-inch suction line, both running 25 feet in length, along with a 3/8-inch drain line. This configuration supports proper refrigerant flow and condensate removal in a single pre-assembled run. HVAC technicians install this line set during new mini split installations or when replacing damaged lineset runs on existing systems.

This line set is suited for residential and light commercial mini split applications where a 25-foot run is required between the indoor and outdoor units. The 3/8-inch liquid line and 3/4-inch suction line diameters are common sizing for single-zone mini split systems operating in a typical capacity range. The included drain line simplifies rough-in work by bundling all three lines into one routed assembly, reducing installation time and keeping the penetration clean through walls or chases.

Key Features

• 25-foot line set length for standard single-zone mini split installations
• 3/8-inch liquid line and 3/4-inch suction line diameters for proper refrigerant flow
• Includes 3/8-inch drain line bundled in the assembly
• Pre-flared ends reduce field fabrication time on the job
• Insulated suction line helps maintain system efficiency and prevent condensation

Compatibility

Designed as an OEM-style line set for mini split systems requiring a 3/8-inch liquid line, 3/4-inch suction line, and 25-foot run length. Consult the outdoor unit installation manual to confirm line set sizing before installation.

Installation Notes

Installation should be performed by a licensed HVAC technician holding an EPA 608 certification, as this work involves refrigerant-side connections. Power down and disconnect the outdoor unit before making any connections. Avoid sharp bends in the line set that could restrict refrigerant flow or damage the tubing wall. Follow the equipment manufacturer's installation manual and all applicable local mechanical codes for line set routing, support spacing, and penetration sealing.
