Meter Star 3/8 Inch Copper Pipe Extension Connector, Flare Nut Double Joint for Air Conditioning Tubing

Air conditioning and refrigeration line repairs can require a clean way to connect or extend copper tubing without brazing. This Meter Star copper pipe extension connector is designed as an intermediate double joint for 3/8 inch copper tubing, helping technicians handle field repairs, new installations, and tubing modifications.

The flare nut design forms a mechanical connection by tightening with a standard wrench. Its no-welding structure helps reduce the need for welding equipment during suitable HVAC copper tubing work.

Made from 100% pure copper, the fitting is intended for air conditioning systems where corrosion resistance, vibration resistance, and thermal cycling performance are important. It fits 3/8 inch copper tubes, approximately 9.5 mm diameter.

Package includes 2 flare nuts and one pair of connector bodies for a complete connection set. For systems with dual tubes of different sizes, confirm each tube diameter and select the matching connector size for each line.
