So I went to the Home Depot over on Country Hills a few weeks back looking for a very basic, generic, male to female adapter to connect my BBQ (Weber Spirit) to my Condo Balcony. The two sales guys brought me to the garden hose fitting sections and handed me a plastic connector. I just smiled, said thanks, and as I was away put the connector down and left the store.
Went to BBQ's Galore and they handed me the piece I needed and I was out in 2 minutes flat. Connected no problem.
Sorry I realize this is no help to you, but perhaps Point # 2 here may have some relevance to you?
