>You mean three of these
you mean more than 3 of those cans. also if you had ever used them, you would realize they have constant slow leaks, so it wont actually have a full 12oz either

>There's a shut off valve at the can and at the manifold
that can doesnt have a valve and again you retard, you have to purge this manifold and the fucking 8 - 12 feet of hose hooked up to it

>manifold
and lol at the poor who previous larped they had gauges now having to admit they only have a manifold. pic related sadly has no room for my fieldpiece leak detector

now post your 609 cert
