Video Transcript for Review of JR Products Propane - Regulators - 37207-30375

Today, we're going to take a look at the JR Products, excess flow two-stage POL RV LP gas regulator. Now this is a low pressure, two stage gas regulator that ensures a nice smooth, continuous flow of gas to all your appliances by combining a high pressure first stage and a low pressure second stage regulator, all into one unit. You can see on this end it has the POL inlet connection to connect to your gas cylinder. And it does contain an excess flow safety device, which will limit your gas flow, in the event of a severe leak. On this end, here is a three eight inch female FPT outlet connection.Now, the vent on here, here's your vent, the vent is actually in the nine o'clock vent position is what they call this. But you do want to make sure when you install this regulator, the vent has to be pointing down.

So the water and debris will not collect inside the regulator. So when you do install this with the vent down, it will be installed in a horizontal position. On the very top it does use a gauge port that you can unscrew this screw right here, and attach a pressure gauge to it.It has a nice zinc die-cast construction. They do use the molded rubber diaphragm. So it is UL approved.

Notice it does have the dust cover that you can unscrew and access the adjustable screw in there to adjust the pressure of the regulator.Has a nice powder coat finish to it. And the BTU capacity on this is 225,000 BTUs per hour. It does come with a nice set of detailed instructions on how this operates and how you install it. But that should do it for the review on the JR Products, excess flow two-stage POL RV LP gas regulator.

  • Should RV Propane Regulator Smell Like Gas
    The vent on regulators like the # 37207-30375 should not allow you to smell propane. If you are smelling propane near the regulator that's a sign yours is bad and needs to be replaced as there's most like a hole in the diaphragm. The # 37207-30375 would be a great solution to replace what you have with.
