Tea20 standard motor Engine Block Drain Tap

kaesark · Oct 6, 2018

Would anyone know what thread the brass engine block drain tap is.
My guess is NPT or BSP

Don't know the type but it is a parallel thread rather than tapered .

The tap on mine is shot but there is quite a few on eBay but they claim to be NPT which is not very common, I would rightly or wrongly have assumed BSP as more likely.

There seems to be some dissension about this thread , another very skilled and accomplished enthusiast says that it is ,
'' 1/4” BSP. Parallel thread''.

I would be very interested to find out which is correct for my own records Kaesark .
