OIL Temperature fitting thread size???

Gentlemen,
What is the thread size for the oil temp fitting that comes with the Smiths gauges? It seems to be sloppy in a 3/8 NPT. It looks tapered compared to the 5/8-18 end that gets the bulb and cap. Anybody remember? I got a 3/4 NPT hole in the pan, so I am looking for a bushing.
Thanks
John

Duuuuhhh, I hate senior moments..... the oil temp fitting thread size I was looking for IS the 5/8-18 end. The other one is threaded for the cap.
