Meter Star Copper Pipe Extension Kit, 1/4 in and 3/8 in Flare Nut Double Connector for HVAC Refrigerant Lines

Air conditioning refrigerant line work can require secure connections for extensions, repairs, retrofits, or custom HVAC installations. This Meter Star copper pipe extension kit provides a no-weld solution for joining 1/4 in and 3/8 in diameter copper tubes in residential or commercial air conditioning systems.

The kit features copper construction for thermal conductivity and corrosion resistance. Precision flare nuts and double-joint connectors are designed to create secure, vibration-resistant connections for use with separately purchased copper tubes.

For installation, align the compatible copper pipe, fit the connector and flare nut, then tighten with a standard wrench. The kit is suitable for DIY users, HVAC technicians, and professionals working on refrigerant line extensions, connection points, maintenance, or repair tasks where welding is not desired.
