Beduan 304 Stainless Steel Compression Fitting Ferrule, 1/2" Tube OD x 1/2" NPT Male, Straight Adapter Connect with Double Ferrules

Good quality fitting is obviously machined properly. Stainless appears to be of good quality and is non-magnetic (a further sign that this is 3-series stainless).

These adapters are made from a high quality stainless finish. I am using them on a pool chlorinater so need corrosion proof. These are the ones to get, price is right also.Note the seller provided great customer service as well to sort out a little confusion I had in the order.

Worked great. Just as described.

I purchased two of these fittings for a project. After assembly, I couldn't get any flow through the system. After disassembly I isolated the issue to the center of the fitting blocked off. I had to drill a through hole through the center. After finding the problem I inspected the second fitting and found the same condition. Otherwise the quality of the fittings was good.

Fit and finish were good, no leaks. Worked well to add NPT quick-disconnects to my stainless homebrew immersion chiller.

These fittings aren't cheap, but they are high quality. They did the job for my project.

I bought this to adapt a 1/4" NPT fitting to a braided stainless steel water line with 1/4" compression fittings. I don't know what the thread is on this adapter, but it was NOT a 1/4" male compression thread. It would not thread onto my water line and ended up galling its threads and breaking it entirely. Now I have $30 in broken parts, a leaking water line, and a derailed project. I'm extremely disappointed and frankly pissed off.
