Mapp gas

[turnpin]

Sometime ago on here I read about Mapp bottles being recalled I have tried to call up the title of the original posts but my system keeps responding with page not found for some reason .....how can I identify the faulty bottles as I have just come across 2 spares in my shed that have been there a while thanks regards turnpin

I think the good ones have a little black square or diamond on the shoulder of the bottle.

black square means new valve, the old one only leaked if you removed your torch. leave it on no leak.
