Meter Star Copper Pipe Extension Connector, 3/4 in Flare Nut Double Joint for 6-19mm AC Refrigeration Tubes

When an air conditioning or refrigeration copper line needs an extension, repair, or intermediate joint, welding may not be practical for every installation. This Meter Star copper pipe extension connector offers a no-welding connection method for compatible copper tubes, helping simplify HVAC piping work.

Made from pure copper, the connector is designed for durability, corrosion resistance, and thermal conductivity in climate control applications. The flare nut design helps create a secure seal when the fitting is properly matched to the tube size and tightened evenly with standard wrenches.

This 3/4 in flare nut double joint supports copper tubes from 6mm to 19mm in diameter. It is suitable for split-system air conditioning and refrigeration pipe connections where a copper tube extension or repair joint is needed.

For installation, match the connector size to the copper tubing, insert the tubes into the intermediate connection head, and tighten the flare nuts evenly. Verify the required tube sizes before purchase, especially for split AC systems that may use different line diameters.
