1/2" PEX-AL-PEX Tubing (1,000 ft Coil)

I ran 1300' of this stuff, 1000 of which said Rifeng and 300 of it said Bluefin. Works well with the screw on compression couplings and was decently easy to work with. It marks the footage on the tube every 5 feet, which is nice. You can't really unreel it, you more have to roll it out, like a carpet. I didn't kink it once, but I knew it was kink prone; a contractor had to disconnect a segment to avoid re-running an electrical line and kinked it all over. I did have a puncture from a flooring nail and the same contractor drilled into it at another spot. 1/2" Repair couplings are not sold by SupplyHouse at the time of this review (Jan 2017), but are available elsewhere. You definitely need repair couplings since you probably will need to cut out a kink or puncture. The tube is very rugged, but stuff happens. As far as the screw together compression couplings, you will need a nice tube cutter (get the Uponor one) and the chamfering tool to make good connection. Push the tube all the way onto the barb, tightening the connector does not pull the tube down, just tightens the collar, so you need to make sure you got it all the way on. Easy if you know, leaks if you don't.

The 3/4 inch is a beast to work with and will kink easily. It would be suitable in very few circumstances. I reccomend trying the 1/2 inch pex-al-pex before you try this or just buy 1 roll to see if you can manage it.
