About the 14
14-4 Shielded Mini-Split Wire By the foot
14-4 shielded mini-split wire is a four-conductor stranded copper cable designed to connect indoor and outdoor units in ductless mini-split air conditioning and heat pump systems. This wire typically carries both power and communication signals between components and includes a grounding conductor for safety.
Key Features
- 14 AWG stranded bare copper conductors for reliable conductivity and flexibility
- Shielded construction with aluminum foil tape and drain wire to reduce electromagnetic interference
- Color-coded insulation (typically black, white, red, green) for easy identification during installation
- Rated for direct burial and outdoor use with sunlight-resistant PVC jacket
- Suitable for both single-zone and multi-zone mini-split applications

Where the 14 fits
Piping, fittings and line-set accessories are code-driven: material, size and pressure rating have to match the fuel or refrigerant they carry and the local mechanical code. The 14 is stocked for the installer who needs the right fitting today, not a substitute that passes at first but fails inspection.
Refrigerant piping and gas piping look similar on the shelf and are not interchangeable: refrigeration copper is cleaned and capped to keep moisture and debris out of the system, and gas fittings are rated and listed for fuel service. Using the right one is a code requirement, not a preference.
Background reading: EPA Section 608 refrigerant rules.
What to check before you order
- Size and material match the pipe or tubing you are joining.
- Refrigeration-grade (ACR) copper and fittings for refrigerant lines; CSST or black iron per code for gas.
- Pressure rating and listing for the application.
- Thread sealant or brazing alloy compatible with the fuel or refrigerant.
Installation and service notes
Cut copper square and deburred, braze with nitrogen flowing to keep the inside of the joint clean, and pressure-test with nitrogen before pulling a vacuum. Gas piping is sized by length and load from the code tables, sealed with a sealant rated for the fuel, and leak-tested at the code pressure before the meter is turned on.
