Well, you're in luck because here at Barbecues Galore, we pride ourselves on having expertise in the area of gas fitting because we get it... this type of stuff is confusing. Together, we can figure out what you need.

Let's start with the common problems with measuring your gas fittings.

With competitive price and timely delivery, ABYDA sincerely hope to be your supplier and partner.

Your keen mind might have thought, "If the inside diameter is what we are measuring, how could the 3/8" quick disconnect have the same inside diameter of the 3/8" hose if one goes in the other?" Well my friend, it's because the world (of gas fitting) works in mysterious ways... but that's why we're here.

Fittings get their name based off of the hose they fit with. That being said, you're right - the inside diameters would not be the same. Thus, the inside diameter on the female end of the Quick Disconnect Nipple would have to be more closely similar to the outside diameter of the male end of your gas hose. For example:

Due to this, we advise you to make sure you know the proper measurement of your natural gas or propane hose first. With that, you'll be able to know the measurements of the Quick Disconnect Nipple and Coupler that you'll need. However, if it's the hose that you're looking for, you now know how to find which hose is needed and we've got them in 5', 10', 15', and 20' lengths.

Lp has more than twice the btu per cubic foot that natural gas does, so jet sizing will have to reflect this.
Also when switching over you no longer need the propane regulator as you will be using the domestic service regulator at the meter to control pressure.

Another item concerns volume and pressure. Since you will need at least twice the volume of nat. gas vs. propane, and the pressure is much lower, sometimes, but not always, you may need to enlarge the fuel valve offices as well as the jets. Most valves will flow adequately at the lower pressures of natural gas, but not always. You will know that you have to enlarge them if you can only use your burner on the high setting. But most valves will usually work with both gases.

Remember when resizing jets it's the area you want to increase to reflect increased flow, don't just double the diameter, think area. If you go too large just solder the hole shut and re drill. I find welding tip cleaners work well to ream out an existing hole "just a smidge bigger".

PS: Flame temps when mixed with air are essentially the same for both gases.
It's cost per btu and convenience you're after.
