Any experts with natural gas fittings ?

[02ebz06]

I have orders a natural gas assembly for my Pizza oven.
Picture below shows the fittings where I plan on connecting to.
Gas line in is on top, down goes to back patio for a firepit or whatever.
I plan on using the connections going to the left.

What I don't understand is why it would have quick-disconnect fitting on the end.
Doesn't seem too safe to me.
Also the on/off valve has been there for more than a decade I imagine.
Concerned the handle would break first time I tried to use it.

Wondering if it is usable as is, or should all that stuff be replaced with new ?

Would like a quarter turn valve with a metal handle like the one for back patio.
Don't know it I would trust the Pizza oven valve and would want to turn the line valve off as well like I do with the propane tank.

Maybe getting someone that knows what they are doing would be smart.

That’s all pretty standard gas plumbing. The quick disconnect is fine to but you could do away with it if concerned. The handles on those valves should all be metal not plastic. Looks legit to me.

Quick connect ends are pretty normal for those. Generally a yellow hose off the quick connect indicates a stationary feed, blue would be mobile. And if you have the gas shut off before the valve you want to replace, I say replace it. Always nice to have good valves that you can trust.

I'd lose everything back to the Tee . New valve and all 1/2 " pipe .
