Arrived as described. Disappointed to discover that does not carry mounting brackets for their regulators, but I welcomed the opportunity to dust off my diy skills. Note the bailing wire. Super pro! Also, if anyone knows what happens when one uses a vertical regulator horizontally, I'm all ears.

Thank you for the review! It looks like the vent placement is one the main differences in the two kinds of regulators. They are placed in such a way that debris from the road will is less likely to clog them. When using the vertical regulator horizontally, the openings are more likely to get clogged which can be a safety issue.


The problem I was having was orange flame on the stove. Looking on line it said that was caused by a defective propane regulator. We were using a humidifier, with the humidifier turn on we got orange flames with the humidifier turned off blue flames.


Love that it works in freezing temperatures! Perfect for our off grid living!


Exact replacement to what the camper came with. It works great with no issues


The mounting holes (4) in the back were not threaded, so we could not use them. We have tried this type of regulator from Camo and Mr Heater. They use the same type of mounting holes / plate and are cheaper, but they stop working after about 3 yrs. We have tried the Auto switching regulators, for two 100lb tanks, they don't work at low temperatures (<0F).


400k btu’s an hour. Hard to beat that


MB Sturgis is a quality OEM part on many rvs and the price is right.


Good company to buy from. (first time, but not the last) I think the gas regulator the camper came with never worked right sense it was bought new. First time it has worked right. The original one was mounted wrong from the factory. Parts got here quick, good packaging to keep from getting damaged in transit.


I don't know much about propane but this regulator was just what I needed and it works perfectly fine. I was glad I could find one at


It's exactly what I needed for the perfect fit. One year later, very happy with the product and would definitely buy again if needed.


Working as designed. No issues with the installation. Be careful plastic black cap on the 2nd stage may be loose as was mine. a challenge to retrieve it where it fell, of course as is always the case. All is well


The propane regulator I ordered seems to be made of quality as does the flex hose. Will order again when I need. Thanks ..,....

..Merry Christmas to all.


I ordered two items from and received my order within delivery and savings make this my primary RC parts retailer.


Best regulator of all .Will continue to work in very cold weather.


Good overall. Time will tell with dependability. As usual these days, not the exact same quality of what it is replacing.


Works as described and gets the gas to my appliance.


Mounting holes not tapped. No thread cutting screws. No mounting template.


I’ve had to replace my regulator twice. So far this one is working great.


Product was shipped quickly and worked well.


Reasonable price,fast shipping.Has laster longer than original.



No problems


Promptly delivered and perfect for our application! Gas is back up and running!


Worked perfect. no more leaking propane.



Works as it should!!


Product worked as advertised and received in timely manner.


Got what I ordered on time good price great delivery what else could you ask for great experience!;


product arrived in just a short time and well packaged
This is for a project down the road but I am confident it will work just fine.

  • Screw Size Needed For Mounting The MB Sturgis 2-Stage Regulator
    Since this type of regulator is typically mounted to a copper propane line you wouldn't need to mount it, but yes, the four holes on the back of the MB Sturgis # 108220 2-stage regulator will allow you to mount the regulator. The holes aren't threaded but the metal is soft enough that a # 8 1/4 inch machine screw would cut threads perfectly into it, Just be mindful that you don't push the screw too far and damage the regulator.

  • Is 12.5" Water Column Too High For and RV Propane System
    No, 12.5" water column is not too much for an RV propane system. Most propane regulators found on an RV system like the MB Sturgis Vertical 2-Stage Propane Regulator # 108220 are going to have a water column of around 11". But, the pressure can range up to around 14" water column before the regulator would be considered to have "failed". So, 12.5" water column is just fine.

  • Inlet of MB Sturgis Propane Regulator
    The inlet of the MB Sturgis propane regulator # 108220 is a 1/4 inch NPT fitting although I'm fairly sure I know why you think it seems to be a 1/2 inch. When reaching out to our friends at MB Sturgis here is how they explain it. If you measure the inside diameter of the female opening you'll get 0.55 inches. NPT fittings like the regulator uses are sized to coincide with the inside diameter of Schedule 40 pipe. So if a 1/4 inch Schedule 40 pipe has a 1/4 inch inside diameter, the outside...

  • Regulator With High Btu for Appliances
    A regulator with enough Btu per hour for your application is the MB Sturgis Vertical 2-Stage Propane Regulator # 108220, which has a 400,000 Btu per hour maximum flow capacity. I do have to say that it sounds like you have a residential type of application and our products are designed for use in recreational vehicle applications so you will need to be sure to keep that in mind for your set up and ensure via professional installers all the correct equipment for your needs.

  • Troubleshooting Weak Flame on RV Propane Stove
    Does the stove possibly have a regulator on it? If you are feeding regulated propane to a stove that has a regulator you would lower the pressure too low. It's also possible your regulator is clogged or in need of replacing. For that the # 108220 would work great. I attached a review video for this regulator as well.

  • Troubleshooting A Regulator That Freezes Up When Hooked Up To A 40lb Tank
    Both the 20lb and 40lb tank should have the same outlet pressure running to the regulator so that leads me to believe that either the 40lb tank is bad and pushing a lot of water into the line or that your regulator is on a flexible hose and when you hook up to the tank the vent on the regulator is no longer facing down allowing the water in the line to escape. I would first make sure that the regulator is in a position so that the vent is facing down and then I would test the system using...

  • Regulator for Running Two 90,000 BTU Fryers on Food Truck

I have attached a short video demonstration on this product that you can also check out.

  • Where Would Bearing and Sleeve Come From When Removing Propane Pigtail on RV
    It was a part from the regulator. It most likely is something that shouldn't have happened. The leak you have most likely came from the regulator. A new one like the part # 108220 which is a dual stage vertical regulator is what you'll need.

  • Regulator & Hose For 100 Pound Propane Tank to Travel Trailer
    Your travel trailer likely has a regulator with an automatic change over valve built into it. As you probably know, when the first bottle is empty it switches over to the second bottle. The bottle and switch are before the regulator, so only the one regulator is required. I suggest that you replace the very short pigtail hose that connects one tank to the regulator with a longer hose that will connect to the 100 pound tank. In that way, you can run off of the 100 pound tank till empty...

  • Is 100-Lb Tank Sufficient Source for 100,000-BTU Heater
    I contacted Hayward and was advised that a 100-lb tank is the recommended minimum size to use with one of their 100,000-BTU pool heaters. Please note that Hayward residential pool heaters are normally configured to operate on natural gas (NG). With the right parts professionally installed one can be converted to operate on propane. The pool heater will have to be operated with the type of fuel it is designed for. The regulators and burner orifices are different and it is not possible to...

  • Regulator for Dyna-Glo Wall Heater Model # IR30PMDG-1
    I looked up your Dyna-Glo wall heater Model # IR30PMDG-1 and it's propane requirements are a 100 lb propane tank using low pressure propane. It's max BTU rating is 30k too. Based on that the # 108220 that you referenced would work great.

  • Typical RV Propane Hard Line Sizing
    Gas lines on RV's are typically 3/8" OD with a some being 1/2" OD so 3/4" pipe would likely be a bit overkill for your needs. The MB Sturgis Vertical 2-Stage Propane Regulator # 108220 you referenced does have a 1/4" Female NPT inlet and 3/8" Female NPT outlet so you'd have to check with your local hardware store for an adapter fitting/hose to go from these to 3/4" pipe.

  • How To Switch From Two Propane Tanks To a Single Propane Tank

  • Troubleshooting A Propane Heater That Only Runs On High
    When a propane heater won’t stay lit, often what is happening is that the propane heater may sense that the flame is defective in some way, triggering the propane heater’s safety functions and causing it to shut off. The problem may be a genuine defect or it could be an issue with the sensor. If it’s flickering, split, small, orange or yellow-colored, then the pilot tube needs to be cleaned. You can clean it out by turning off the gas first then gently poking a needle into the top of the...

    Yes, the MB Sturgis Vertical 2-Stage Propane Regulator # 108220 will work just fine with your 3 90,000 Btu fryers/stove.

  • Do Fryers with Their Own Regulators On a Food Truck Need a Regulator on the Propane Tanks
    Propane can be a pain to understand sometimes but we are here to help! The short answer is yes, having an additional regulator can be a bad thing, but if you check the manuals for your fryers they should say whether you need high pressure or regulated propane running to them. On a typical RV setup you're going to have your propane tanks connected to a regulator that then feeds into the propane piping that runs throughout the RV. Different appliances may or may not have another regulator...

  • Troubleshooting Regulator Vent Leak and Regulator Replacement
    There are a couple things you can try to narrow down your issue and find the correct option to fix it. First, you can make a mixture of dish soap and water, generously apply the mixture to your regulator. With all flames shut off, open your tanks and look for leaks. The soap/water mixture will bubble. Since you said that the leak didn't start until you changed your propane tank you may have a propane tank that was overfilled. Which is causing too much pressure and causing the regulator...

  • Recommended 11-14 Water Column (WC) Rated Propane Regulator for a Generator
    The water column (WC) rating of the Single Stage Propane Regulator part # 108072 would be far too high for your generator. Instead, you are going to want to use a two-stage regulator like the MB Sturgis Vertical 2-Stage Propane Regulator part # 108220 which will supply between 11-12.5 inches of water column. The two stage regulator would also supply more BTU's for your generator in comparison to a single stage.
