Features

GasStop™ is the only emergency 100% shut-off safety device for bottled and portable propane systems with ACME type connections. In the event of a major leak, GasStop™ will instantly and automatically shut off the flow of gas. This device is designed for DOT propane bottles in your RV. If you have a propane leak in your RV, there is no device that will completely stop the flow of propane into your RV until now. The existing OPD and excess flow valves on a propane tank will not 100% shut the propane off should you have a leak. When you use the GasStop device, you will have 100% confidence that if you have a propane leak the propane will be shut off from your RV immediately. INSTALLATION is very easy. All you do is install the GasStop device directly to the propane tank, and then attach your RV propane line to the GasStop device. Now just prime the GasStop device and you are instantly protected. Remember, if you have 2 propane tanks, you will need to get 2 GasStop devices. GasStop™ is also very useful in helping you detect that minor leaks that occur anywhere in your propane network. When you buy from TechnoRV we will make sure you understand how easy it is to use the device and to understand how to use it as a leak detector.

100% automatic PROPANE SHUT-OFF in the event of a major leak.

High-quality gas pressure indicator to help manage propane supply.
Highly engineered brass construction, easy to install, and backed by a five-year warranty.
Patented technology that is UL listed and approved.

GasStop will completely (100%) and automatically shut off the supply of propane in the event of a major leak or catastrophic regulator failure. The excess flow valve is essentially a spring-loaded cylinder that acts only if the flow is over 200,000 BTUs/hr. If the flow is over this amount, the valve is triggered and stops 75-90% of the propane flow. So, what about the remaining 10-25% that is not stopped? This propane still flows and can quickly fill the RV up if there is a major leak, so it does not offer the level of protection needed in RVs.

For an increased level of propane monitoring, we recommend the Mopeka Propane Monitor. The Mopeka Propane Monitor is a sensor that monitors the level of propane you have remaining in your tanks and shows it on a phone app, so you never have to run out of propane in the middle of the night again! It is simple to install the heavy-duty magnetic monitoring device on your propane tank, and the app shows you your current propane level in the tank, with updates every 5 minutes.

GasStop can be used with any automatic or manual changeover gas pressure regulator, as long as it is rated at 1.5kg/h and up to 20” W.C. You’ll need to install a GasStop on each tank attached to the changeover device so both tanks are protected.

In addition to shutting your propane off in the event of a major leak, the GasStop device can be used to check for minor leaks in your RV. It’s a simple process and takes only 5 minutes. This is something you could do every time you set up your RV to ensure nothing happened within your propane system while traveling. We provide detailed instructions on how to do a leak test in the Learning Series you receive after purchase.

Really works

Just installed #4&5 gas stops on a larger trailer we plan to live in, already have them in my travel trailer. But the real test was with a friend using a really large propane on his mother in laws fifth wheel. I suggested the gas stop for safety, her trailer had a leak when we hooked her up, the gas stop kept shutting off as designed. We found the leak, repaired it, the gas stop may have saved a life. I am a believer, wouldn’t be without one now.

Continued confidence with GasStop

We have used GasStop's for multiple years to reduce any propane leak probability on our travel trailer. We have been pleased with results.

Gas stop

Hopefully I never need to use it for what it's intended for. It's a great product for safety that has been proven to work.

Peace of Mind

It was easy to installed, I needed two. Installation was about 45 seconds and now if there is an issue while we travel we know we are better protected. We do not leave the propane on while we travel, but road hazard debris is always a concern to L.P. plumbing when you get to your campsite.

The two that I have kick off when I start my generator. I was told they were improving the design to handle that initial pull of propane from a generator. Can you advise if these are the updated devices?

Good afternoon. We do carry the updated GasStop valves for the higher propane flow rates from most generators. GasStop defines a leak as sudden and dramatic change in the gas flow rate equivalent to a flow rate of 70 standard cubic feet per hour (SCFH) or more. A real world example of a “sudden and dramatic change in the gas flow” is the complete and immediate rupture of a propane hose during a fire or tire blowout. GasStop is also calibrated to shut-off at ≥125% of the guaranteed flow rate (UL requirement).

I have a 5th wheel which has two 60 lb tanks with auto switchover. Will the GasStop Propane Shut Off - ACME Style (GSUSA2) work? Thanks.

technorv 12/01/2023

Good morning. Thank you so much for your question! Yes, the GasStop valves will work on those propane tanks that share the auto switchover. You would need one GasStop valve per tank. You may want to double check the GasStop that you would need. The ACME style is more for the portable propane tanks that average about 25 pounds. Larger (typically built in) propane tanks may take the POL end connection style of the GasStop product.

I bought two of the gas stops for my RV and when I got them it said grill on the package. Will they work on my RV? Thank you Richard

Thank you for bringing this to our attention! I do see where an exchange was made for the correct GasStop valves in the past. It appears there was a shipping error and the incorrect valve types wre originally sent. Please do reach back out to us if we need to take further steps. We will be happy to do so!
