Weber Q conversion to run off house tanks

There have been a number of threads about converting BBQs to run off the RV propane tanks. Most questions center around which fittings to buy, where to buy, and how to remove the BBQ regulator.

I'm starting a new thread because I just purchased the fittings I need from Calore Equipment and wanted to share some information. (Their site: www.caloreequipment.com )

First, the customer service has been excellent. I've had a number of questions and they've been answered quickly and accurately. Not only that, when I corresponded with a senior member of the management team about obtaining a 1/8" fitting for the Weber Q, he immediately recognized that folks with that BBQ could use a 1/8" fitting and put one into production.

Second, they have the fittings you need. To save people time, I'll list what I bought with part numbers:

1. #401153 1/8" MNPT - 250 Male quick disconnect (for the Weber Q...this is the fitting newly in production...so you no longer have to step down from a 1/4" fitting!)

2. #104052 Female quick disconnect and ball valve assembly (this is to put on the RV. For safety, I'd recommend using a valve...either integrated as I did or get a separate valve)

3. #100395-120 10' RV dual quick disconnect hose (to connect RV to BBQ)

4. #302004 Dust cap plug (to cover the fitting on the BBQ when not in use)

5. #302005 Dust cap socket (to cover the fitting on the RV when not in use...turns out you don't need this as part 104052 comes with a dust cap)

If you're measuring fittings, this is a great resource:

I haven't made this modification yet. I still need to go to my trailer and figure out which fittings I need to attach the female QD/valve assembly to the existing plumbing. Those fittings should be available locally and will vary depending on your RV (...mine has a hard gas line running down the length of the trailer to the water heater in the rear...I'm going to tap into that line where it branches off to feed the water heater, stove, or heater).

In terms of cost, with shipping I spent $95 and will likely spend another $5-10. I can buy a lot of little propane bottles for that amount of money. For me, it's about the convenience of not having to stock up on propane. I figure if my trailer manufacturer offered a "BBQ quick disconnect fitting with 10' hose" for $100, I would have checked that box without thinking about it.

The person who helped me at Calore asked me to send photos of the installation so they can use them to help others making this modification. I'll also post them here once this project is finished.

    I need to correct my original post.

    I still haven't modified my BBQ (I have one small propane bottle left to use), but another member pointed out to me that the WeberQ has a MNPT fitting to which one attaches the quick disconnect.

    Part #401153 (1/8" MNPT - 250 Male quick disconnect) is MNPT. Ideally, you want it to be FNPT...I haven't checked with Calore, so I don't know if they make one. The easy workaround for part #401153 1/8" MNPT is to pickup a 1/8"FNPT-1/8"FNPT coupler at Lowes, HD, etc. Sorry about the inaccurate information!


    JR, that's what I found out too. The Watts coupler from Lowes is needed if you're not going to put the ball valve on the Weber. The ball valve is female/female and would eliminate the need for the coupler if you went that route. You use the Watts coupler between the Weber's 1/8" male NPT and the Calor fitting you posted originally then just hook up your hose. Easy setup.

    I have a ball valve on my trailer's quick connect so did not see the need for 2.

    I have a line all the way to the back of the RV as well as hoses already.
    Do I need all the list as on the first post or is the part #401153 enough? will my current quick connect hose fit this fitting?
    why are there some fittings 1/4 and this one is 1/8?


    If your hose has the female quick disconnect on both ends, all you should need is the Calor fitting and the Watts coupler. If your hose has the threaded end (same threads as on a disposable tank) you will need a different adapter for the Weber if you choose to remove the Weber's regulator, which some leave on and are satisfied.

    Here's a link to how I did the conversion, which basically borrows from jrichard's info:
