Natural gas connections question
I have a 1/2 inch connection from the house with 2 hoses to grill and separate side burner. I want to add a quick connect on the side burner to be able to easily swap to a "crawfish burner". I can easily find 3/8 connections but 1/2 is much more rare.

Can I use 1/2" hose to 3/8" connector then back to 1/2" hose/burner? Is there a problem using fittings to make 1/2 to 3/8 with quick connect?

re: Natural gas connections question
You might be causing yourself a bottleneck and not get sufficient gas supply to properly run the burner doing that. I've never lived anywhere where 3/8" fittings are easier to find than 1/2". Assuming your grill is attached to the gas line with a quick disconnect, why not use a 2-way QD fitting on the gas line and simply run another hose?

re: Natural gas connections question
Natural gas from the house has insufficient pressure to run a crawfish burner. You might do a search on here as it has been discussed a bunch before. Most of the threads end with people just using the propane bottles.

I have been using a natural gas wok burner set up for years without any problems other than breaking out wrenches to connect and disconnect the hoses. Just trying to find a quick connect setup to make it easier. Looks like Amazon has the 1/2 inch quick connects for about $25 each.

Here's my setup, FWIW:


Amazon has a 1/2" quick connect fitting. Most grill stores should have the hose. Tejas Smokers has them as well.


As for the comment above:

This is utterly incorrect. I've been using natural gas to boil crawfish for 20 years.
Does it take a little longer? Yes
Is a NG jet burner quieter? Yes
Do I ever worry about running out of gas mid-boil? No

It's all in sizing the burner & jets to match the fuel.

Massively different amount of BTU's involved. You can boil crawfish water over that gas line but it takes forever. Like I said before, you might want to search for the threads with people who have tried it and said it's a no go.

re: Natural gas connections question
I don't have to search for anything as I do this on a regular basis.

As I said, my 135,000 BTU/hr NG burner takes a little longer, but I'm not in a hurry. But to say that you CANNOT boil crawfish with natural gas is completely in error.

I thought that was the OP replying. Didn't realize we had a NG expert roll on up in this bitch to put the smack down on anyone with a differing opinion. You be you Hoss. And take it to the OT if you want to be so damn argumentative.

All I said TO THE OP was he might want to do some research before he commits.

Whatever chief. I tried to help OP with a real world installation and useful information.

So go somewhere else with your bullshite, and in the meantime you might want to change your tampon.

Maybe because they didn't have the proper NG connection. I have two 1" connections off the meter; one supplying my water heater, furnace, and range and the other at the back of my house for grill/fryer/crawfish pot etc. More than enough BTU/H but I have properly sized plumbing for demand and the distance from the meter.

re: Natural gas connections question
Bc your home NG is a low pressure, the key is to provide as much volume of gas as you can. The closer in size you can get to the size of you piping and the closer you can get to the meter the better. There is a formula, google it, to calculate how much volume you can get based on you pipe size, length and number of 90’s in the line. You also have to take into account the flow rate of your meter, you can get a little over the stamped rate but not much.

I had a fight with entergy last year when they changed out my meter. The std 250 cubic foot (or whatever) meter is insufficient for our house. I eventually had to total up all the max BTUs from the plates on all the gas appliances and generator to prove to them that they f’ed up and replaced my meter with the wrong size. That’s when I went down the rabbit hole on google and discovered the plumbing formulas and calculators to size the piping and meters based on the needed BTUs, pipe length, pipe size, and number of 90’s in the run.
