You're headed to the next campsite, and in the chaos of packing up, you forgot to turn off your propane system. While on the road, someone rear ends you, causing a propane line to come loose, and you now run the risk of a fire breaking out on your RV. It's a dreaded situation that no one wants to suffer through.

Unlike EFVs and other built-in limiters that just reduce the flow of gas, GasStop shut-off safety valve immediately and completely shuts off your gas supply when it detects either a major leak in your propane system or failure of your regulator. This protects both your family and your travel trailer or fifth wheel, ensuring that your camping trip remains safe, fun, and worry-free. And while this safety valve will shut off for major leaks, it won't shut off for minor leaks. This means that your furnace or heater won't go out in the middle of the night while camping in the frigid mountains over a small, less dangerous leak.

Corrosion-Resistant Stainless Steel Construction

GasStop Safety Valve Testing for Minor Leaks

The integrated pressure gauge provides a clear and easy way to tell what your propane tanks gas pressure is while the gas is being used. If it's on "high", there's been an increase in gas pressure, most likely due to excessive heat, and you'll have to cool the tank down. If it's on "gas", then you'll know you still have plenty of usable gas left. And if it's on "low", then it's time to switch out your tanks. The gauge is also rotatable, so it can be used from any angle, though it is recommended to keep it no lower than 45 degrees from the sky.

The gauge can also be used to test for minor leaks. Once the GasStop safety valve has been installed and the gas appliances have been turned off, push down on the gauge 4 to 6 times to see what the gas pressure is. If the needle is below the red bar on the gauge, then one or more of the following is the cause: the cylinder valve isn't open, the GasStop safety valve has shut off, you have run out of gas, you haven't pushed the gauge the appropriate number of times, or the temperature is around freezing.

If the needle is above the red bar, note its exact position before turning off the valve on your propane tank. Wait 60 seconds for standard applications and 5 minutes for longer RV gas systems. If the needle is in the same position, you can continue to use your propane system. If the needle dropped during that time, there is a leak somewhere. You shouldn't use your propane system until that leak has been found and repaired.

Simple Installation

GasStop Safety Valve Installation

This GasStop safety valve is extremely simple to install. Once your propane system and all of your gas appliances have been shut off, tighten the GasStop safety valve onto your propane tank. Then re-attach your regulator and hose (not included) before checking for any leaks in your propane system. To allow the gas to flow, push down on the gauge face 4-6 times.

If your propane setup is in a particularly small or cramped compartment, consider adding a GasGear hose (sold separately). The hose has a 90-degree connection that makes it quick and easy to hook up to your propane tank in tight spaces.

Video Transcript for GasStop Propane Emergency Shut-Off Safety Valve Review

Today, we're gonna be taking a look at some gas stop emergency shutoff valve. So we're gonna have two different kinds, but the gauge is gonna be the same on both. Basically the difference between the two different kinds is your application. The one that we have here, is gonna have a POL connection, so this is gonna be for your motor homes and your RVs where you have tanks that are already pre-put inside your rig, that are gonna stay there. But we have another one that's gonna have an ACME fitting, which is gonna be for your travel trailers and your fifth wheels. Basically, it's just for the tanks that are removable on those different types of rigs, but they both work the exact same.

So let's show you. We have a little test right now. So basically, we're gonna just show you how it works, how the gauge is gonna move down. So let's just say we just hooked up everything, and we want to send the gas through our lines. So depending on how big your travel trailer is, we're gonna have to press this, but since we really don't have a whole lot of line behind this we're only gonna have to do it once, but when you press it down, it's gonna engage the mechanism letting the gas flow through, but this is gonna stimulate a major major leak.

So it literally has gas on one side of it, but it's preventing it from flowing through because there is a major leak. And then once you fix the leak, press it down and then we're good to go. So what we're gonna do now is just go through the situation of you just got this at your doorstep, from etrailer and we're gonna just check and make sure that we don't have a leak. So what we're gonna do is kinda, take this screwed on just like any other. And this is gonna go in between our propane tank and our line.

So now we have our other one, which these are also gas stops. So if you really wanna upgrade everything, we have stainless steel hoses, but also just these normal hoses. The nice thing about the gas stuff we do have a 90 degree, so I really recommend if you're gonna upgrade, might as well get new hoses. So now what we're gonna do since it's all hooked up, we're going to open up our gas, and we're going to press it down. We are gonna have to cycle through a decent amount, just because we have a decent amount of lines.

What we're gonna do is just kinda walk away for a little bit and if this needle starts to go down whenever we come back, it's gonna let us know if we have a leak. So we're gonna wait a little bit to see if we have a leak, I don't think we do but it's always safe to check. And our needle really hasn't moved. So now we know that there is no tiny minor leak on the inside of our trailer, so this is just gonna give me peace of mind. Just knowing that the gas isn't filling up my whole entire trailer, is just something that I think is a necessity when it comes to your propane systems, why not buy something that gives you peace of mind One, you're not gonna fill this thing up with propane and harm somebody. Two, it's just gonna save a propane. So I definitely think that this is something you need to have whenever you are traveling with your propane. As far as the construction goes, it's very very quality. We have the same exact gauge on both, and all of them are gonna be made of brass. So this isn't really some dinky little product, it's gonna last over the years of use, and that is something I really like. I like to spend my money on something that's really gonna last, and this gas stop products is definitely made with quality material, it's gonna last us a long time. The only thing you really need to figure out is just what kind of rig that you have, if you have a travel trailer like this, with the propane's outside, we're gonna go with the ACME fitting. If we have a motor home or RV, we can go ahead and use the POL connection. It all just depends on what you guys got, but this is something that you install, and you'll reap the benefits every single time that you go and check your propane, whenever you're going up on the trip. That's basically it for a look at the gas stop propane emergency shutoff valve..

Great item to purchase for your propane tank to help you monitor levels and have if a emergency or leak happens with your propane tank. Peace of mind when you are out camping with the family. Highly recommend. Check out etrailer for all your RV needs. They have excellent parts and outstanding service when ordering your parts and/or supplies. Love the Company.


The GasStop is well built and easy to use. The instructions are easy to follow and let you know the do’s and don’ts. I like the fact that you can test your systems to make sure you don’t have any leaks and how full or empty your tanks are.
This product will give me piece of mind knowing that we are safe in our 5th wheel


Have not installed as of today, will review at a later date. Great service from e trailer and Amy was very knowledgeable about the part. Thank you Amy J.


Installed 2 gas stops into 5th wheel. Everything works fine. Delivery was great as well as follow up.


It was easy to set up and gave me the relative readings on my two tanks which is what I was after.


Great product.
