Review on 🔌 Boeray 5Pcs Brass Fitting Adapter: Reliable and Versatile Solution for Seamless Connections by Greg Anderson

This was in a pack of 5 which is a good thing. Two of the five were damaged (I don't know how well that shows in the photo) and one of the adapters had such thread damage that it was unusable. Luckily I only really needed two (I installed one as soon as the package arrived so it's not pictured). The point is, if you need all five for something that requires precision carving, you might want to look elsewhere, otherwise it's a good deal.
