Blackstone 5471 Propane Adapter Hose & Regulator for 20 lb Tank, Gas Grill & Griddle - Weather Resistant & Corrosion Resistant - Extends Up To 3 Feet

Was looking for a regulator to fit the 27" grill but couldn't find one so took a chance on this one as the small print said fits other cylinders as well although only promotes the 18 and 22" grills - on arrival the regulator but it has opposite direction threading's (to fit on to the grill) so it’s completely incompatible. I’ve even checked Blackstone's website abut no where on the website do they sell any 27” model, very disappointing

The regulator doesn’t fit onto a flo gas bottle, I imagine this would be the same for a calor bottle as they use a similar push fitting whereas this is a classic threaded attachment. It also states it works with the blackstone 22” griddle but they have opposite direction threadings so it’s completely incompatible. I’ve even checked blackstones website as on the box it states doesn’t work with 22” pro series but no where on the website do they sell any 22” model that’s a pro series nor is it on the box of my grill anywhere that it’s a pro series, seems like this is an outdated product for their current models that are on sale.
