1/2" NPT Tap

[PeterW]

Does anyone have a 1/2" NPT tap that I could borrow, or I would be prepared to tap a hole in a brass blanking plate ..?

 

I want to mount a 1/2 NPT threaded thermowell into a brass immersion blanking plug and I thought I had one but it's 3/8th so wondered if anyone had one lying about ..?

1/2" BSP nearest I've got.

 

With one of these:

Have just realised plan B is more effective and leaves the immersion operational if needed ....

 

Will make a dip tube from the top of the tank through the hot water draw off with a 22/10 reducer ..!

I had a look earlier, but 1/4" BSP or 1/2" BSF were the closest I had -  not much use really!

Thanks both - getting the solder and the gas torch out I think is the answer ..!

Much easier. Have you got leaded solder?

Yep I've got an old reel somewhere and some lovely silver solder too...

Sweet. Brazed will be a doddle.
