Blackstone griddle regulator adapt

I would be interested in knowing this too. I have the griddle and used it on our last trip. I have a propane "tree" that I use for the other grills but I had to hook the griddle directly to the 20 lb tank due to the coupling.

I haven't, but it looks almost identical to my coleman regulator/fitting. I plan on ordering the same parts for the blackstone griddle as I did for my coleman. You just have to remove the regulator and install the quick disconnect.

Remove the regulator, determine the thread size and replace regulator with that size quick connect fitting. Weber is 1/8" NPT, your brand may differ

Nunyadamn, Can you elaborate more on your solution with perhaps some pictures. I have a Coleman grill that I would like to connect to the RV external LP line. The grill connection has a "goose neck" connector to the grill after the regulator. Two regulators in series doesn't cut it, not much heat.

If your regulator does not unscrew, conversion might be challenging.

Update, I currently don’t own the said griddle but I closely looked it over & unscrewed the regulator. With regulator removed you are left with a male 3/16” thread ( best guess!) maybe 1/4” the Q had a 1/8” ( someone else’s measurement) . I won’t buy the griddle until I know that I can make it work on a already regulated line. If I get to Rural King and they have one in stock I may be able to make some fittings work that they have in store but doubt they will have the quick coupler.

There are a couple of threads on how to do it on some other forums. I found this on YouTube, and is what I'm going to do by springtime.

Here is my coleman connection - just remove the stainless piece that goes into the brass piece and put on a 1/4" Female Pipe x 1/8" Male Pipe elbow like in my picture:
Top Coleman Modified vs blackstone not modified

Here is the elbow I used:
Anderson 1/4 to 1/8 elbow

Buy a 1/4" Male x 1/8" Female so you can still use the small bottles if needed:
1/4" Male x 1/8" Female

Here is how that looks:
Regulator with quick disconnect
Quick with regulator

This is the quick disconnect set I used:
Camco 59853

I did the same thing with my camp chef fire pit and I plan on doing it with the two propane tabletop heaters I just bought. The blackstone will be just as easy.

In case anyone is looking for hoses, I use two of these for the fire pit and usually one with the coleman barbecue:
Camco 57282

If you're having trouble finding the right fittings and pieces, see if you have an industrial hose supplier nearby. We have one called New-Line Hose & Fittings that has anything and everything to do with any kind of hoses for fluids or gases. Have had a couple of RV dealers tell me to go there for propane parts they didn't have. Take the pieces you have into them so they know exactly what you need. Or take the pieces somewhere that can identify the thread pitch/size you have and order what you need online.

Posting a pic or two of what you have may help.
