Oh, gosh, I am so sorry to hear that. I already let our customer service team this needs to be addressed.



by:

One year later. The regulator is still working fine.



by:

Easy to install, 10.48" water out of the box on my gauge which is ok.



by:

Works just fine…etrailer has always been top notch with quality parts and quality employees….from warehouse to delivery etrailer rocks….



by:

I was smelling propane out side our RV for a couple of weeks. I diagnosed the smell to the regulator where the vent was leaking. Ordered a new one and replaced, problem solved.

The regulator continues to operate as I would expect it to. Once replaced I have not had any propane related issues with odor or pressure.

@Ron We're glad to hear that!


by:

Quick shipping. Item installed and is working well. Excellent communication from etrailer.



by:

Used to operate propane heater in a van, no complaints.



by:

Arrived a day late, but that's typical of USPS. Had it installed ad leak checked in 20 minutes. Works great. Hopefully this one will last longer than the previous one made in China that failed in less than a year.



by:

Good product for off grid cabin stove. First regulator was defective. Exchange was seamless and e-trailer could not have been more helpful. Great customer service. I highly recommend the company and will be using for any future needs.



by:

Works like a.charm! Exact replacement for a Marshall 260. Even used the same mounting screws. All hookups are standard. Order process was a breeze. Great service and fair price. Highly recommended!

Works like a charm even in hard MN winters! Very pleased with the ease and simplicity of the entire process and install. etrailer.com is the place to shop!



by:

I wasn't excited to be replacing the LP regulator on a two year old RV with one exactly like the one that had failed. That said,etrailer made it all very easy. Good people to deal with.



by:

Exact product I was looking for fast de livery



by:

Works well, nothing special



by:

Easy install. Has not failed us during one year of service. Highly recommend.



by:

This was a replacement regulator on a 2017 Forest River RPod; the original one was leaking and very corroded. This one has been working perfectly for a full year now.



by:

Product has worked well for our needs. eTrailer was fast to ship and updated us along the way. Great all around.



by:

Works great!



by:

The regulator fit in the same place as the older one i had in my RV. I installed this evening and fired the fridge up. It is working as it should.
The reason for the 4 stars is the delivery. it is not E-trailers fault, but the postal service had it for 3 days before was put in my po box.

I have bought from e-trailer before and their service is outstanding.

The regulator is working great. Would buy again.



by:

I Rose G should get the employee of the year award, and a big fat raise, She is Outstanding in Her position!



by:

It has been working for a year now, with no issues. We are using this pressure regulator to provide gas to our tiny house from a 100# tank. It supplies our apartment-sized cook stove, plus the 180k btu/he tankless water heater. So far, no issues! We are using it with a 12ft. for hose from the tank to the regulator. (With a fitting to adapt it). Regulator, hose and fitting came from etrailer.)



by:

I feel this propane regulator is only average at best in quality. This same regulator came new with my new motor home and only lasted three years before the first stage developed a leak through the vent hole. Camping 50 years of my life, I never had a propane regulator fail over the years till now. So now I carry a spare.

Splitshaft

6/18/2022

The new replacement regulator has been installed 10-months and has been used three weeks over that time with no problems.



by:

7 degrees Fahrenheit and working well.



by:

I'm using this to supply a 3 hp generator. It works perfectly. I'm sure it would supply a much larger engine since the supply valve to the carburetor is nearly closed when the engine is at full speed. Great product!

Alan L.

Still working well



by:

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



by:

Perfect. It's an exact match to what I need to get my camper propane system up and running.

  • Recommended Regulator For A Food Truck Using 340,000BTU's An Hour
    For that large of a pull you would need to use a regulator like the # 108220 or # 108221 depending on your setup. Both of these regulators have a 400,000btu/hr rating to handle your 340,000btu demand. The main thing to remember when installing the regulator is to make sure that the vents on facing down so you could need the vertical # 108220 or the horizontal # 108221 to achieve this.

  • Best Horizontal Dual Propane Regulator for RV
    We currently offer three different dual stage horizontal regulators for trailers. If you're looking for the best then I recommend the MB Sturgis Horizontal 2-Stage Propane Regulator part # 108221 as it's made here in the USA. The other options are the Horizontal Low Pressure 2-Stage RV LP Gas Regulator part # 37207-30385 and Camco Horizontal 2-Stage Propane Regulator part # CAM59323 which are great as well. There is always a potential for leaks but ensuring proper installation will reduce...

  • Troubleshooting An E1 Error Code On A Furrion Tankless Water Heater
    An E1 code on your Furrion RV Tankless Water Heater - Gas - Automatic Pilot - 60,000 BTU Item # FR93FR means that it tried to ignite twice but didn't have the correct amount of gas pressure. First check to make sure your gas valves are fully open and if they are you'll need to do it have a licensed technician check the pressure on the line and possibly replace your regulator to ensure you're getting 11" WC. If you have a horizontal regulator you can use the MB Sturgis Horizontal 2-Stage...

  • The Difference Between A Single-Stage And Dual-Stage RV Propane Regulator
    Both single-stage # CAM59013 and dual-stage # 108221 regulators will both reduce pressure down to 11" WC, but the difference is the stability of the output pressure. The single-stage regulators quickly reduce the pressure down and give you a bit less stable of an output, whereas the dual-stage regulators will provide a much more steady flow. I typically recommend dual-stage regulators for this reason. There are 3-styles that we currently offer, vertical # 108220, horizontal # 108221,...

  • Regulator for 2 38,000 BTU Propane Water Heaters
    For the best option, you need a 2-stage regulator like the MB Sturgis Horizontal 2-Stage Propane Regulator - 11" Water Column Outlet # 108221 or the MB Sturgis Vertical 2-Stage Propane Regulator - 11" Water Column Outlet # 108220. The 2-stage regulator provides a more constant stream of pressure which is always ideal for propane applications.

  • Troubleshooting E1 Error Code on Furrion Tankless Water Heater
    The E1 fault on a Furrion RV Tankless Water Heater # FR93FR means you need to check that all your gas valves are open, that you have enough propane in your tanks, and that your regulator is working properly. If your regulator is needing to be replaced then you need part # 108221 for a horizontal option or part # 108220 for a vertical option. If you or the dealer has checked all of this and there are still issues then Furrion states there is a system fault and you need to reach out to them...

  • Recommended Propane Regulator 11 inch to 13 Inch WC Hooked up to 100 Lb Tank
    The standard water column output for RV propane regulators is 11" like the MB Sturgis 2-Stage Propane Regulator part # 108220 for vertical or part # 108221 for horizontal which are what I recommend. That said, you can adjust them higher to 12" by removing the black cap and turning the valve underneath. These can be hooked up to a 100 lb propane tank using the MB Sturgis Propane Pigtail Hose part # 100019-60 and MB Sturgis Propane Adapter Fitting part # 402258-MBS. We don't carry any CCST...

  • Correct Propane Regulator for Wall Mounted 30,000 BTU Heater
    For your 30,000 BTU wall mounted heater you will need to use a dual-stage propane regulator. The correct regulator will be the MB Sturgis Vertical 2-Stage Propane Regulator - 11" Water Column Outlet # 108220. You will need a vertical regulator if your is mounted upright and the vent is on the bottom. If you need a horizontal regulator, the MB Sturgis Horizontal 2-Stage Propane Regulator - 11" Water Column Outlet # 108221 will also work for your heater. You will need a horizontal regulator...

  • Mounting Bracket Dimensions for MB Sturgis Horizontal 2-Stage Propane Regulator # 108221
    The MB Sturgis Horizontal 2-Stage Propane Regulator # 108221 that you referenced does not come with a bracket. I wish we offered one but we do not as most applications already have a bracket for the regulator and this is designed to fit standard bracket dimensions. The holes are 3 inches apart in length and 7/8 inch apart in width.

  • Recommended Regulator For A Motorhome Propane Setup
    Depending on the piping is on your propane system you can use a horizontal or vertical regular. Basically just what fits in the space most conveniently. So you could use the MB Sturgis Horizontal 2-Stage Propane Regulator - 11" Water Column Outlet Item # 108221 for a horizontal setup or the MB Sturgis Vertical 2-Stage Propane Regulator - 11" Water Column Outlet Item # 108220 for a vertical setup. Anytime you're installing a regulator you should always place it so the vent is facing downward.

  • Replacement 2-Stage Regulator Knob
    I do have a replacement 2-stage regulator that may work for you but unfortunately we do not sell the replacement regulator knob you are inquiring about. I recommend using the MB Sturgis Horizontal 2-Stage Propane Regulator part # 108221. As long as the 1/4" female inlet and 3/8" female outlet NPT fittings match your current setup, this regulator will work well for you.

  • Recommended Two-Stage Regulator For A 100lb Tank Fueling A 160,000BTU Tankless Water Heater
    For a horizontal two-stage regulator that's manufactured in the USA we offer the MB Sturgis Horizontal 2-Stage Propane Regulator - 11" Water Column Outlet # 108221. You would just need to attach the MB Sturgis Full Flow Propane Tank Connector Fitting - Soft Nose POL x 1/4" MPT # 204037-MBS to the 1/4" Female NPT inlet on the regulator to be able to connect to your 100lb tank.

  • Option For Replacing Champion LPG Regulator 100157213
    We do have a potential option for you. While we do not carry a direct replacement for the Champion part 100157213 that you mentioned, we do carry a very similar 2-stage regulator with the MB Sturgis Horizontal 2-Stage Propane Regulator # 108221. This regulator has an 11" WC rating and we have confirmed with the folks at Champion that this is an acceptable rating for a replacement. The max BTU is 400,000 so more than enough for your generator.

  • Parts Needed to Connect Manchester 10 lb Propane Tank to 4 Propane Cookers on Food Trailer
    From what I can tell it looks like you need the adapter # 204037-MBS, regulator # 108221, and hose # 100383-48-MBS for your propane setup. I'm not sure what the POL to QCC1 converter is that you mentioned but these parts get you from the POL connector on your Manchester 100 lb propane tank to the 1/2" flared fitting that I believe your picture shows goes to your 4 propane cookers.

  • Will Regulator part # 108221 Fit Standard Low Pressure Propane Applications
    As long as your propane tank is a low pressure application the regulator part # 108221 would be the correct regulator to use as it regulates to the standard 11 inch water column. The hoses and fittings needed would be based on the application though. I'd need more info on the appliance and hose length needed. If you aren't sure what fittings you'd need you can send me pictures.

  • Will MB Sturgis Horizontal 2-Stage Propane Regulator Replace Model 290 Regulator
    Yes it will; your Model 290 is a 2-stage regulator that reduces pressure to 11" WC (water column, which is the standard pressure rating), just like the MB Sturgis regulator. It even has the same inlet and outlet sizes so it will be a perfect replacement and is the following part number: - MB Sturgis Horizontal 2-Stage Propane Regulator # 108221
