What size? I know the Greenlee DTAP comes in 1/4-20.

McMaster-Carr......combination drill bits/taps

GW

do they make a 1/4 npt?
I can't find one large enough at McMaster Carr.
I will look at GreenLee.

Thanks.

Have not seen them in NPT sizes. A truss head bolt will work in PVC, though I would prefer fine threads.

We have used 1/4" thread-serts in single wall vent pipe.

Whose boiler are you using that does not give you a place to test the boiler?

Mostly furnaces, yes most every boiler has ports
