Attaching Blackstone grill to RV LP accessory connector

Take the black pipe out of your Blackstone and unscrew the fitting that connects to its regulator...may need to put it in a vise...that thing is tight. That fitting's threads match that of a 3/8" compression fitting. I bought a 3/8" male to 1/4" npt male adaptor (sku 645791). Screw that on the black pipe and reinstall it (use gas tape). Now screw a 1/4" union (sku 645697) and (I already had) the 1/4" quick connector that fits into the other end of the union on the end. Works great.

Yes, I converted all my appliances (BBQ, firepit, etc) to run off the RV system.
Very easy to do but you must remove the items regulator. All I have seen are attached with a simple NPT fitting and I simply adapted a male quick disconnect to them. Then I made up extension hoses.
You could skip the extensions and just connect the rubber line to the BBQ. Ebay has many of them.
I did all this because there was no safe or convenient way for me to carry a cylinder.

This pic may be confusing but after removing the reg, I was left with an 1/8" male NPT. I could have used an adapter fitting to convert that to the male quick disconnect but I just tapped the inside of the QD to accept the 1/8NPT.


The conversion on my fire pit:

I have two 10' hoses and one 5' hose'. I can use one or all of them.
I also made a hose that has the BBQ's regulator (because it has the highest flow and will work for anything) on one end and a quick disconnect on the other. Using that, I can still run any of my modified appliances off a bulk cyl.

I have about $100 wrapped up in all the hoses and fittings.
