Hi all
Here's the situation - I'm building a brewery and I'm following instructions found on this page
http://www.theelectricbrewery.com/heating-elements?page=7
Basically, the heating element is inserted through the skin of the brewing vessel and a seal is provided by a silicone o-ring on the outside. A nut is then used on the inside to hold the element in place.
Thing is, I'm in the UK and I'm ordering these products from the US so all the threads and such are NPS... the only thing I can't easily source from the US is the nut that holds the element on the inside.
I appreciate that the NPS and BSP standards are fairly close but they are sufficiently different for them not to be compatible.... however I've read one website saying you shouldn't use them together if a good seal is required...
This begs the question, considering the seal is provided by the silicone o-ring on the outside and all I need to do is to do is find a nut that will hold the element in place firmly, can I use a nearly-compatible BSP nut on the NPS thread?
Cheers!
