Sweet pea boiler fittings

[Paul Roberts 6Participant @paulroberts6]

Hi all I have a Sweet Pea in 7 1/4″ gauge (yes that’s right, I didn’t mean a Sweet William)

I need some new boiler fittings for it. Most aren’t a problem as I know pretty much everything is 1/4×40. However I can’t for the life in me remember what size the water gauge fittings are. Although I do know that they are as per the drawings. My problem is that I can’t get back to my loco for a couple of weeks and I don’t have a copy of the backhead drawing on hand either. Would somebody be able to tell me what size water gauge fittings I need. 5/16×32 seems to ring a bell but I couldn’t swear by it.

Thanks

Thanks for your reply.

Ok. Maybe my boiler wasn’t made exactly to the drawings then…..

I’ve just today found one of the blanking plugs for it. It’s 32tpi instead of 40
