2Packs AC Copper Pipe Extension Joint Connectors, 3/8-Inch Air Conditioning Pipe Coupling Adapters with Flare Nuts and Connectors, Free Welding, For Butt Copper Tube Diameter 3/8" (9.53mm)

I kinked my lineset when installing a new condenser. Decided to give this a shot before scrapping the whole thing for new. Passed pressure test and has been fine almost a year. Seems great to me.

Mini split connectors. Perfect size

great price and quality

Good quality

as described these seem to be good quality and my flares fit them well

Everything included worked perfect. You will need a flaring tool to install these but that’s obvious. I was able to cut out the kinked like and splice in a new one without any soldering.

They fix the what needed to be fix in 5mins.It beat welding the 2 copper pipers together. Thank You.

These are better quality than those at the local hardware store.
