This 2-stage regulator can deliver a massive 400,000 Btus an hour while keeping pressure at 11" WC to fuel all your appliances. Must be installed horizontally when used on an ASME tank.


  • 2-Stage regulator lowers pressure from your RV's propane tank so it can be used by appliances
    • First stage reduces tank pressure to 10 psi to stabilize gas
    • Second stage reduces pressure to maximum of 11" WC to make flow safe to use
    • Can maintain 9" WC pressure to keep appliances running in cold temperatures
  • Max flow rate of 400,000 Btu per hour is one of the highest available for Class A, B, and C RVs
    • Use multiple propane-fueled appliances at once without flaming out
  • Downward-facing vent allows condensation to leak out when used with ASME tanks
    • Must be installed horizontally to allow water to drain
  • 1/4" Female NPT inlet and 3/8" female NPT outlet connect your propane tanks to the supply lines
  • Aluminum construction approved for LP gas only

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

This one is a two-piece unit that tends to leak propane. I wouldn't recommend it.


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.


Exact replacement for my rv.


The product has worked well. No issues.


I wish it had a mounting plate that came with it. I had to make the old one fit.


Shipping was delayed but received regular communication about what was going on which was greatly appreciated.


I have used etrailer several times and every time I am please with the service , shipping, and products. etrailer is definitely a company that I look at and use due to the vast amount of products for RV’s and trailers.


Part arrived quicker than I expected and worked as expected. Useful information on the website helped me make the right choice.


Took awhile to get it but it's as adve rtised


Very Fast delivery worked as discribed.


Seams to be the equivalent item that I will use when needed. Spare part now.


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!


Great experience Allison k was super nice LP regulator was the one I ordered and needed no one else had it I would definitely use them again they follow up it's all good five star


Item sent was exactly what I ordered and needed. After installation leaking problem was resolved. Thank you.


Ordered item one night and received it in less than a day. They shipped to where I was and not my home address. Could not ask for better service. Thank you.


Was way better quality than the cheap camco replacement that I purchased elswhere.


Have not installed yet but I like the fact that it has a high btu flow rate


It’s working great.


Worked great, good quality.

Looks like the real deal, good product.

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.

I ordered so I have a spare part on hand. My son-in-law handles what parts to order. I was very impressed with the fast shipping.


eTrailer confirmed my order and notified me when it shipped. I received it within a couple days. Appreciated the communication and prompt service.


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.)


Good price, good product, fast delivery. It’s the perfect trifecta.
