Worked on 1/2" copper tubing
I had a dishwasher connection that used 1/2" copper tubing with flare fitting attaching to valve. Replace the valve with 1/2" compression and needed this fitting to cut off flare and use this fitting to make transition to use stainless steel braided hose. The 1/2" NPT threads on the fitting seemed a little tight in connecting the stainless steel braided hose. I added some food grade anti-seize thread compound to make disassembly easy later.

Quality connector but required brass compression swage lock rings to properly seal.
I purchased this swage lock stainless steel fitting to connect my stainless steel 3/8” hard tube line to my an-6 flex fuel supply hose. The supplied stainless steel sewage lock tube compression rings did not compress enough to create a proper seal, allowing fuel to leak. I had to use swage lok brass compression rings. They sealed properly.

HD Quality Stainless fittings
This Horiznext 304 stainless steel compression fitting is for connecting 1/2 inch OD tubing to 1/2 NPT male threaded pipe. It’s made entirely of type 304 stainless steel, heavy-duty and corrosion-resistant. The machining is perfect. The split ferrule compression design grips the tube tightly, preventing leaks in any demanding setup. This connection can be done up, undone, and reconnected many, many times if you don't abuse it. Rated for 600 psi and temperatures from -100 to 660°F, this fitting is at home in industrial or lab environments, as well as DIY. This fitting is a quality, reliable choice for connecting stainless steel tubing to threaded pipes.

Made well but not for basic 1/2 inch home copper tubing
Made very well with some weight to the items. However these do not fit a basic residential application. I did not understand that they do not fit over 1/2 inch basic copper tubing used in home plumping.
