I've posted this elsewhere but wanted to close the loop on this thread.
I really like my Weber Q120 and was looking forward to converting it to run off my newly installed LP port. I found a lot of information online but for the life of me couldn't find the right parts to make it work. The gas valve was looking for a particular fitting that the big box stores and other places came close, but not exact for the fitting.
Torjik makes a kit called ConvertaQ ( link here: http://torjik.com/#_convertaq
) that fit perfectly. This is definitely more expensive than buying components at a big box store but the fit here was perfect. Even better, they worked with me to create a custom hose with a 3/8" quick disconnect since that's what the rest of my setup is with the Genconnex LP conversions on my Honda generators.
They were great to work with and the kit took about 15 minutes to install. If you're a fan of your Q and want to run it off your LP port, check them out.
To be clear - I'm not affiliated with these guys at all, I paid full price for my kit and I'm not compensated by them in any way. I'm just so dang happy I finally got what I needed I'm psyched to share the info! 😀
