GREE Mini-Split Line Set 1/4"x5/8"x25 ft, 14-4 AWG Wire & Insulation

Refrigerant and Electrical Line Set for GREE Mini Splits, 25 Ft

A mini-split indoor and outdoor unit can't run without a matched line-set connecting them, and mismatched or improvised wiring is a common source of installation delays and callbacks. This GREE line set solves that by pairing correctly sized 1/4in x 5/8in refrigerant lines with 14-4 AWG wire and insulation in a single 25ft kit built for compatible GREE mini-split systems.

At 25ft, this set reaches the typical distance between an indoor air handler and outdoor compressor in most residential or single-room installations, giving installers both the refrigerant lines and the electrical connection without sourcing them separately.

Key Features & Benefits

• 1/4in x 5/8in refrigerant line set — sized for compatible GREE mini-split systems.

• Insulated lines — helps maintain refrigerant line efficiency along the full run.

Who Should Use This Line Set

This fits installers and owners of compatible GREE mini-split systems who need a matched 25ft line-set with wiring included, rather than sourcing refrigerant lines and electrical wire from separate sources.

The lines are sized 1/4in x 5/8in, matched to compatible GREE mini-split indoor and outdoor units. Confirm compatibility with your specific system model before ordering.

Does this line set include the wiring needed for installation?

Yes, it includes 14-4 AWG wire and insulation alongside the refrigerant lines, so installers get both the refrigerant connection and the electrical run in one kit. That avoids sourcing wire separately from a different supplier.

How far does a 25ft line set reach?

25ft covers the typical distance between an indoor air handler and an outdoor compressor in most single-room or residential installations. Longer runs need a different line-set length.

GREE's dealer resource page carries submittals, spec sheets, install manuals, and certificates for this line set. Check there before starting an installation.

Is this line set compatible with any GREE mini-split system?

It's sized for compatible GREE mini-split systems, but not every GREE model uses the same line-set dimensions. Confirm the required line size against your specific indoor and outdoor unit before ordering.
