2Pieces Copper Pipe Extension Joint Connectors for Air Conditioning Pipe Coupling Adapters with Flare Nuts and Connectors for Copper Tube Diameter 3/8 and 1/4-Inch

Just what I needed! Dealers look at me like where is your contractor license? Dismissed! These couplers Work! Had to extend a line set, Works, no leaks!

Extremely useful coupler for mini-split. I’ve been installing mini-splits throughout my place. Unfortunately, one of them needed a 24ft pipe set rather than the 15ft pipe set it came with. The mini-split cost $699 and if I wanted a 25ft pipe set it was $225 extra. Two of them only needed 5ft of pipe so I cut them to size, used the supplied fittings and a cheap pipe flaring tool and they were done. This left me more than enough of an offcut to use the supplied spare fittings and the flaring tool to make an ‘extension’ pipe set. It was then a simple job to use this coupler set to join the pipes together, saving well over $200 The unit works perfectly, no leaks. Simple, effective and not just excellent value for money but saved over 20 times what they cost! Highly recommended.

Product works as intended.

Perfect fit , no leaks under vacuum & with pressure. It’s good to see quality workmanship. Made job a lot easier, didn’t have to silphos any fittings just used these connectors.

Returned, didn’t need.

Great for mini split linesets.

These worked perfect to extend my mini split line set. I did buy the flare gaskets and I also used nylog on the fitting. It was a good value for me vs buying a longer line set since I had extra pieces of line already. It fit the lines perfectly, had no leaks, and was easy to splice 1/4" and 3/8" lines together.

worked perfectly. Make sure you flare the pipes right.
