Pyrometer probe depth

[cozinsky]

I have an Autometer pyrometer and installed it today. My crossover pipe has a 1/4" NPT female bung welded into it and the probe bushing is 1/8" NPT male. If I put a reducer bushing between them this pushes the probe out of the pipe, leaving basically only the tip exposed inside. Is this going to give an accurate reading? I can't seem to find any bushing with 1/4" threads that will fit the pyro probe and eliminate the need for a reducer between them.

This may not help, but can you drop your crossover pipe and weld a 1/8" NPT bung in it? Then all you'd have to do is put a plug in the existing one.

I finally found and ordered this:

That should be what I need, although I'm not sure if the nut on my probe will fit it so I might have to cut the shrink tube and take the wires apart again to switch nuts.
