What size NPT probe 1/4 or 1/8, for EGT

Wanting the 2" Westach, dual,combo--(boost and EGT)--they come in both sizes---what size should I use??

have 05, 325/610 CTD------thanks, R

you can run either. I usually run the 1/8" first just for the "in case" situation. I can always go larger if the threads get messed up.

Isspro thermocouples are 1/8" NPT. They also come with an adapter for 1/4" NPT. Other brands may also, but haven't installed any other brand, yet.
