Review: Couplers that work, with no leaks! - 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!
Review: Saved hundreds of dollars. - 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.
