Review on Stainless Steel Reducing Hex Bushing - 3/4" Male NPT To 1/2" Female NPT Fitting For Pipe And Hose (Pack Of 1) by Kristopher Tight

Mine looked nice with machined surfaces like the picture, but the male thread is huge. This means if you have a blind hole and can't run the tap very deep, you won't even be able to get the fitting started in the hole. I ground my cheap tap a few 1/16's at a time and retapped, but only got half a turn in. Would be nice if they had these available with the male thread diameter reduced for blind holes. Only option would be to reduce the thread on a cnc lathe to maintain taper. Wishing I tapped hole with straight thread at this point.
