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.

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.

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.)

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!

I just installed the regulator and everything went easy except there is a bracket the old regulator was mounted to but the new regulator screw holes dont match up. I have tie wrapped to the bracket until I figure out a better way to mount it. Background - I purchased a new regulator because the fridge was not cooling enough and found out the regulator was not putting out the correct wc. So I have turned the fridge on and now it is wait and see. The flame/pilot looks better though.

I just installed this regulator in May, 2018 to replace a failed CAMCO regulator. I have had 4 Camco regulators on a 2015 Camper and they either leak or won't let gas through. The installation of this Sturgis regulator was fairly easy and it works great now and hopefully for a long time.

We were not able to use the oven in our r.v typically could only use one burner on a three burner stove and the front heater only put out warm air. Wasn’t sure what the issue was but there was a common issue happening . Ordered the regulator that actually came a day earlier than expected was able to change it out with no issues and all previous problems were solved.

Seems like better quality than other similar regulators I've tried. No propane smell when turning on the gas now, pretty simple fix. Hope this one lasts as long as the one it replaced (same one) !

  • 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. If you have something else please let me know. I have attached a photo showing how these parts are typically...

  • Recommended LP Gas Regulator for 100 Lb Tank
    The MB Sturgis 2-Stage Propane Regulator part # 108221 for horizontal mount or part # 108220 for vertical mount is what I recommend for a 100 lb tank. It does not matter which you choose so long as you have the vent pointed downward. These regulators will work just fine with both propane and lp gas. In order to connect either regulator you can use the MB Sturgis POL Propane Tank Connector Fitting part # 204051-MBS or the MB Sturgis Hose Assembly part # 100202.

  • Propane Regulator Recommendation for 2000 Coleman Bayside Elite Pop Up
    I checked out your 2000 Coleman Bayside Elite and it looks like it uses a dual propane tank setup at the front of it so for a regulator I would recommend the # 37207-31525 which connects to both tanks and has the ability to switch between the two tanks easily and automatically so you don't have to worry about switching tanks when one is empty.

It does not matter which you choose so long as you have the vent pointed downward. I much prefer the dual stage regulators over the single stage as they are more accurate, perform better in the cold, and most can be adjusted if needed. The above two options will will be plenty for a water heater and stove. In order to connect either...

  • Garage LP Wall Heater Regulator for 30k BTU Application
    As long as the heater you are installing is an LP (low pressure) propane heater that requires 11 inch water column pressure the part # 108221 would work great as a regulator. It is capable of up to 400,000 btu so it would easily handle your setup that is 30,000 btu.

  • Recommended Propane Regulator Needed for Outdoor Range with 100 Lb Propane Tank
    The requirements for your outdoor range will dictate the correct regulator. That said, the MB Sturgis Horizontal 2-Stage Propane Regulator part # 108221 provides up to a 400,000 Btu per hour output which will surely be enough for your outdoor range. It will also work with a 100 lb propane tank using the MB Sturgis Sturgi-Stay Propane Fill Hose part # 100019-144 and the MB Sturgis Propane Adapter Fitting part # 402258-MBS.

  • Largest Propane Tank for Use With MB Sturgis 2-State Propane Regulator
    The highest-quality regulator we carry is the MB Sturgis Horizontal 2-Stage Propane Regulator # 108221, so I reached out to MB Sturgis, and they told me that their regulator is only recommended for use with propane tanks up to 100 lbs. For your application, since it is such a large tank, they recommended contacting a propane distributor who specializes in such large propane applications.

You will not have any problems using either of them on your 2015 Coachmen Clipper 17BH.

  • Propane Is Leaking From Vent On Regulator
    It sounds like your propane regulator is bad and needs to be replaced. These are not repairable which is why you need to replace yours and it's pretty easy to do. I see you were looking at a dual stage regulator so if that is what you have then you just need to choose the one that has the vent oriented correctly, part # 108221 for horizontal or part # 108220 for vertical.

In order to attach the regulator inlet to your 100 lb propane tank you will need the MB Sturgis Sturgi-Stay Propane Fill Hose part # 100019-15 and the MB Sturgis Propane Adapter Fitting part # 402258-MBS.

    You can indeed replace your existing single stage regulator with the MB Sturgis Horizontal 2-Stage Propane Regulator # 108221. I spoke with my contact at MB Sturgis regarding its performance in cold weather when compared to a single stage and he did say that what you read is true. This is because of the piston design that MB Sturgis uses for the 2-stage regulators that allows it to maintain the needed pressure as temperatures drop. This design is actually unique to their 2-stage units and...

  • Single Regulator for Switching from Dual Tank Setup to Single Tank
    A dual stage regulator like the part # 108221 would work great with your single 100 lb propane tank setup. Your current pigtail that goes from the tank to the regulator should work just fine as the 100 lb tanks do not use a different fitting size. Regulators do have a orientation they need to be in so the vent is operable. this one needs to be horizontal.

To connect your 20 lb propane tank to the regulator you need a pigtail. Since you have about 3' you need to cover I recommend the 36" MB Sturgis Propane Pigtail # 100473-36-MBS.

  • Should Stages of Propane Regulator be Separated for Clearance to Install on RV

  • Replacement Propane Gas Control for 1980 Yellowstone Camper Trailer

  • Regulator Recommendation for a Trailer with New Water Heater
    The line may be 1/2" in diameter but I am willing to bet the fitting is a 3/8". Regulator # 108221 has a 1/4" female NPT and 3/8" male NPT. The output will be an 11 inch water column so it is within the range needed by your water heater. I have linked a video that covers the features of the regulator. Another option is # CAM59333 which has a POL fitting that can screw directly into a 20 pound tank or any size that accepts a POL fitting. The other ports include a 1/4" inlet and a 3/8" outlet.
