Mapp/Pro Gas + 2no Oxygen for Oxyturbo Portapack Kits Bullfinch

oxy is normal standard bottles but map has a finer thread than standard map gas as used in UK - it wont fit your torch or if u really are an idiot and force it, it will wreck your torch!! the standard connection has 3 threads on cylinder and this has 4 in same chord. i only needed oxy so this map thread was only an annoyance. then again, if u do own a torch that takes this connection..... theyre very similar and same diametric dimensions, same yellow.... jst soooo easy to get the wrong one.
