Review on Stainless Steel Thread Fitting Adapter by Richard Gallagher

Was very pleasantly surprised to see that the tube connection side had a larger tapered bore compared to the Russell aluminum connections I had on hand. I assumed the difference in price was for stainless steel but the running of the machine was worth the difference as I bought it for nitrous oxide. No burrs, all smooth edges, excellent threading and no loose spots commonly found on cheaper stainless steel hardware and fittings.
