<div dir="ltr">James, as this is a tapered pipe thread (NPT in states) , I would buy a pipe tap that fits this thread and cut the female threads a bit deeper by running the tap until it lands and then getting a few more turns on it with a wrench. This should enable you to get a few more threads engaged. As Jon notes, it would be easy to test joint by connecting a pressure washer with a bypass valve and a pressure gage and subject it to a pressure 1.5 times the design depth. IF it is leak free, you are good to go.</div><div dir="ltr"><br></div><div dir="ltr">Cliff</div><div><br></div>
