Meter Star 1/2 Inch Flare Nut Copper Pipe Extension Connector for HVAC and Refrigeration Lines

Extending or joining an HVAC or refrigeration line can require extra time and equipment when welding is involved. This Meter Star copper pipe extension connector provides a practical intermediate joint for connecting two 1/2 inch diameter tubes in air conditioning repair, refrigeration service, and copper pipe extension work.

Made from 100% pure copper, the connector is built for HVAC/R service use and corrosion resistance. The 1/2 inch flare nut connection helps create a secure, pressure-tight fit without welding, making installation more convenient for line repair and extension projects.

The kit includes 2 flare nuts and a pair of connectors for one connection point. It is intended for 1/2 inch diameter tubing and may be used with copper, aluminum, or steel pipes of the specified diameter.

Before ordering, confirm the outside tube diameter required for your system. Many air conditioning systems use two line sizes, so a full line set extension may require separate connector kits in the correct matching diameters.
