Video Transcript for Review of JR Products Propane - Hoses - 37207-30715

Michael: Hi there. I'm Michael with today we're taking a look at the Jr products, propane hose. This is going to connect between your LP gas cylinder and your regulator on your RV so that you can use all your RV appliances. You can see on this end, we have the RV type one or ACME. It's also sometimes called the QCC1, fitting. This is going to Mount onto your RV's gas cylinder valve.

It's going to be very simple to install. You only have to hand tighten it, and you're not going to need any special tools or anything like that. And it does install clockwise. So it's going to be very easy. Most of us are familiar with tightening things clockwise and some of the other valves out there are counter-clockwise.

So it's a little counterintuitive. This fitting is going to provide a high flow rate before it goes into the bypass mode.The bypass mode is when the system thinks that there's a gas leak. So it brings it down to minimum flow. This allowing that high flow rate, it's going to allow you to power all of your RV's appliances at once before it goes into the bypass mode. So you're not going to have to worry about that.

On this end, we are going to have the quarter inch male inverted flare in, and this is going to connect to your regulator. This hose also has the internal back-check to prevent any sort of gas leaks. It is designed for LP gas, only LPB of course, liquid propane, your hose dimensions. It's going to be right about a foot. It's actually slightly over from the end of our nozzle there down to the other end.

It's about 12 and a half inches. So we have plenty of links for you. If you're looking for a one foot hose, it's got an internal diameter of a quarter of an inch. This hose is UL and CSA certified, and it is made here in the USA. And that's going to complete our look at the Jr products, propane hose..

Propane hose assembly connects your dual LP gas cylinder setup to the regulator on your camper. Internal back-check prevents gas leaks.


I installed the lines and they work well. No issues. This was a second order attempt to get the correct fittings for the regulator recommended for my RV. Besides the frustration of returning and reordering all is good!


Excellent quality,hard to tighten it with narrow jaw crescent wrench or channel locks,got it tight with channellocks but squeezed the hose fitting!So far no leaks and I hope it stays that way!


Great quality thanks


Exact replacements of original pigtails from 20 lb. propane tanks to the travel trailer's regulator. Seems to be of high quality. No leaks detected after installation.


Great products, ordering is easy and shipping is timely.


Very good company to work with and I appreciated the help Becky provided.




Fast shipping, quality product

  • Replacing Winntec 6020 Regulator on RV Propane Setup
    The Winntec 6020 regulator that you referenced is a low pressure regulator like what the JR part # 37207-31525 you referenced is designed to replace which will work great. The pigtail you'd need depends on the length that works best for you. # 37207-30775 is 3 feet with a back check, # 37207-30745 is 20 inches with a back check, and # 37207-30715 is 1 foot with a back check. Back checks prevent the hose from leaking in reverse basically where it attaches to the tank. It's a great feature...

  • Recommended Replacement Hose From Propane Tank to Regulator on 5th Wheel
    The hose and fittings sizes are standardized for RV's. Therefore, what you have is going to be a type 1 to either a 1/4" NPT or 1/4" Male Inverter Flare. If you have the former I recommend part # 100473-12 or part # 37207-30715 if you have the latter. That said, I get why you're confused as these fittings don't actually mic out to 1/4", they will measure larger but that does not correlate to their nominal size which would be the same for measuring any sort of NPT fitting.

  • Replacement For Winntec 6020 With Ill-Fitting Pigtail Hoses
    We do not have a pigtail hose that is larger than the 1/4 inch, which is the standard size, and the Winntec 6020 is honestly something I would replace, as it has been recalled in the past. Due to this and the hoses not being available, I highly recommend going with a better quality automatic changeover regulator with standard size pigtail hose fittings: - Automatic Changeover RV LP Gas Regulator # 37207-30395 Then for a pigtail hose you can use any of the following, depending on the length...
