    I ordered a pair to thread into the oil cooler in my 88-98 GM 1500. The adapters fit perfectly and no leaks! I was able to do away with the stock oil cooler lines and make braided stainless replacements, thanks to threadtoolsupply.com!!

    Ordered these to interface from 1/2" liquidtight to camera junction boxes. Looked great and worked amazingly well. If I didn't have these, it would have looked awful.
