The fittings have manufacturer’s code stamped on the fitting body. The male stem protective cap is identified as 6. They do react to a magnet. In natural light the fittings appear whiter than the photograph. They may be treated steel or stainless, am unsure which.

I believe it may be similar to Worldwide Fitting F5506-06, 3/8 male-3/8 female.

This auction is for 50 fittings. All are new. As you can see in the photograph, some have lost their protective caps, but appear to be undamaged.
