Thanks for taking time to reply!According to the picture of that hose, the description is wrong. The description says the hose has a 3/8 male flare connection, but the picture shows it as female.
And then your description says you are looking for a female adapter, but your picture seems to show that what you really need is a male adapter to go into that tee.
It looks like that the flare end of that hose should screw into the fitting on your firepit.
Also, coming out of your house you should really have a shutoff valve. It looks tight, but hopefully if you removed the pipe strap you can pull the pipe out enough to spin on a ball valve and the fittings that you need to get to that hose. Maybe you could go with a 3/8" shutoff valve to save some room.
So, here's what I would suggest (listed in order with coming out of your house)....
3/4" x 3/8" black malleable bushing
3/8" black iron close nipple
3/8" threaded ball valve
another 3/8" black iron close nipple
then your hose going to your fire pit.
Hope this helps. Keep in mind that you will need a conversion kit to run that fire pit on natural gas. You can't just replace propane with natural gas and hope it will work.
I agree that description is confusing and so am I
On one end it looks like a female flare https://imgur.com/a/iT6z6JF
and other one is hard to guess.
Yes, I will need to put shutoff valve and space it definitely tight, but I hope once I loosen clamps at that tee it will give me more space to install one.
With your list of parts I think I might have better luck at the local harware store.
I already have conversion kit on the way, just need to bring gas to the fire pit.
