Video Transcript for Review of JR Products Propane - Hoses - 37207-31465

Michael: Hi there. I'm Michael with today we're going to take a quick look at the JR Products Propane Hose, like most of your propane hoses this is designed for LP or propane gas to flow through it so that you can power up your propane-powered appliances. Now when you're shopping for propane hose, there are a few things that I would recommend looking for.The first thing is obviously going to be the links, if you want it to be able to reach from point A to point B so that you can get that propane to flow through there. This is a four foot long rubber hose, so as long as your point A and point B are less than four feet from each other, this should work for you. The rubber hose construction is going to help it resist any kinks or cracking anything like that. It's got an internal diameter of three eighths of an inch, which is plenty of room for that propane to flow through there, so you should be able to run all of your propane-powered appliances at the same time without having to worry about it.The next thing that you want to look for are your hose fittings.

You want to make sure these are going to fit your current setup. There are several different kinds of fittings out there, so you want to find the ones that are going to work for you. Here we've got our three eighth inch male NPT fitting. This is what's going to connect to your regulator in most cases depending on your setup, you would want to check that. The other fitting we have here is a half inch female swivel SAE fitting.

Let me pronounced that again S-A-E fitting. That's a type of fitting here. The swivel head is going to make it very easy to get this installed. You're not going to have to trim the whole hose to tighten it down. That swivel fitting there will make it easy for you.So you do want to check to make sure that those are the fittings that you need for your setup.

We do have many different options here at if that's not the part that you need. Keep in mind, this hose is UL and CSA approved, so it's going to meet those quality standards. You can trust that it's going to hold up well and do the job you need it to do.And like I said, if this isn't the hose that you need, maybe it's a too long, too short, or you've got different fittings, I'd encourage you to come to take a look at our other options here at Our goal is always to help you find the product that's going to solve your problem so you can get back to enjoying your time outdoors. That's going to complete our look at the JR Products Propane Hose..

I ordered a 4-foot hose as an exact replacement for an old, cracked hose. The hose I received was a 5-foot hose. It's not at all what I wanted, but I had to use it. No time for a return. It doesn't look at all organized. Not happy with this part.

Thank you for letting us know about this. I have sent your information to our customer service team to see what we can do to help. They will be reaching out soon!

  • Propane Adapter Hoses to Use as Extension for Regulator
    Yes, if you are talking about the inner of a propane regulator. The 3/8" male NPT fitting on the 3 hoses you asked about and are listed below, is the most common size for a regulator. But, there are some that use other sizes so you would want to verify that is what you have. - Propane Hose # 37207-31465 - MB Sturgis Propane Adapter Hose # 100383-36-MBS - MB Sturgis Propane Adapter Hose # 100383-60-MBS The other ends of these hoses are 1/2" female fittings, again you would want to verify...
