What Size of Natural Gas/Propane Hose and Quick Disconnect Do You Need?

Are you getting ready to connect a new grill, patio heater, or fire table? One question that might be on your mind is, “What size should my gas hose and brass fittings be?” You’re in luck! Here at Burnaby Manufacturing, we specialize in gas fittings and are here to guide you through the process. With a little proactive reading, you’ll know exactly what you need.

Common Problems with Measuring Your Gas Fittings

Many people unknowingly buy the wrong size fittings for their natural gas or propane hose because they don’t know how to measure it correctly. It can be confusing, but we’re here to help clear things up.

There are three common measurements people often consider:
1. Outside Diameter (OD)
2. Nominal Pipe Size (NPS)
3. Inside Diameter (ID)

But only one of these is correct when it comes to gas hoses and fittings.

How to Measure a Hose

The measurement you want is the inside diameter (ID). Remember, ID stands for “inside diameter.” For instance, a 3/8″ LP/NG hose has an inside diameter of 3/8″.

How to Measure a Quick Disconnect Nipple and Coupler

You might be wondering, “If the inside diameter is what we’re measuring, how can a 3/8″ quick disconnect fit with a 3/8″ hose if one goes into the other?” Good question! The world of gas fittings can be a bit mysterious, but here’s the key:

Fittings are named based on the hose they fit. This means the inside diameters aren’t the same. The inside diameter on the female end of a quick disconnect nipple must be similar to the outside diameter of the male end of the gas hose. For example:

– The female end of a 3/8″ Natural Gas Quick Disconnect Nipple and Coupler has an inside diameter of about 5/8″.
– The female end of a 1/2″ Natural Gas Quick Disconnect Nipple and Coupler has an inside diameter of about 3/4″.

To avoid confusion, always ensure you know the proper measurement of your natural gas or propane hose first. With that measurement, you can determine the size of the Quick Disconnect Nipple and Coupler you’ll need.

Hose Lengths

Once you know your hose size, we have two lengths available: 5′, 10′.
