Good adapter, good quality.
Used this so I could adapt a GM sensor to my Lamborghini for the standalone ECU I am using, and it's dimensionally great. Zero issues, fit perfect, did exactly what I needed, even came with a copper seal. Very happy with it.

Well made adapter just make sure get right one
Amazons website said the 1.5 was what I needed for my 03 GMC Envoy but I really needed the 2.0 adapter. I stripped out some threads on my block trying to force it (((((((((so make sure you have the right threads))))))) on your adapter. Ended up getting the 2.0 from Summit Racing in Georgia and using a lot of permatex thread seal and crossed my fingers when turning engine on. (Installed an aftermarket oil pressure switch and gauge). I think amazon has the 2.0 which are larger male threads than the 1.5.

Just what you need for an LS swap
Works great for my 2000 5.3 Ls swap into my 1969 Chevy truck. Removed the stock oil pressure switch, threaded the adapter in and my 1/8" stock oil pressure line fit right into the adapter. works perfectly and is hidden behind the intake.
