I believe the connector in my link is proprietary to the Blackstone...
I already have a 20Ft hose with Quick Connect for my grill as well as a regulator and hose with a quick connect for same.. The 1/4" connector as shown in the link should fit either..
I also carry a 10lb regulator with 10ft hose and quick connect for my shrimp boil pot's burner.. now that thing will suck some propane..
