Default Thread size in head for heater/heat sensor

I'm placing an order for a Spal 16" fan from Summit and figured to order the switch at the same time since there's a 10% Memorial Day discount.

What is the thread size something or other NPT for the heater connection heat sensor?

Probably need another 'Y' as well?

Any suggestions I'm all ears.
