Holdrite QFC-17524 QuickFlex Water Heater Connector, 1-Inch FIP by 3/4-Inch FIP by 24-Inch, Aluminum

Works perfectly for our water softener and it is very sturdy

I would not have believed it. Stayed completely unkinked. But it does keep some amount of pressure pushing back against the bend, trying to straighten itself out when very short radius bends are made. I think the tightest bend recommended is about 5 or 6” diameter (obviously half of that as a radius). My softener tank tilted over a few degrees (lifting one side of the tank bottom about an inch or so off the floor) if I tried to make the bend very tight so I pulled the tank back a few inches so it stood up straight. I bet I could have strapped the tank tight to another tank next to it, to keep it vertical, and gotten my few inches back, with no problem. It seems like it would last longer than a braided hose, since it’s solid metal.

Worked very well. Easy to fit & thread into fittings. Put some "white" Locktight for easy removal/ disassembly if needed in future. No leaks, no kinks, no troubles. 100x better than those braided flexible hot water tank lines available at HOME DEPOT. In which the plastic liner on the discharge side of mine deterioted and had plastic flakes coming out of my bath faucet!..only 8 yrs old.

Excellent product. Some projects require unions, but this product offers far greater flexibility while still giving me union-like maintenance ability. Strong, malleable. Excellent product!!

These are really nice. They look professional and flex. I had a pair of nylon types on my water heater before that broke down over time leaving 'black' water in my lines. The nylon lines were a bit more flexible, but these flex just fine. Solid fittings at the end and had no leak with clean connection and use of quality thick teflon tape. The box stores did not have these, but they should.
