I was a little concerned about using a quick connect on propane but I have to say Mr Heater got this one right, The first one worked great on my 175,000 btu torpedo heater and I bought a second one for a radiant heater. Both heaters are hooked up to 100lb tanks and the connections are solid. Easy to install and easy to use. I used a little Teflon tape on the threads but I'm not really sure that was needed.
