Replaces the gauge on your Valterra adjustable water regulator.


I needed a new gauge for my water regulator. While not a Valterra the specs were identical. It was easy to find, order and was quickly delivered. Very happy with the new regulator. It was an easy replacement since the Teflon tape was already on the connection.



The new gauge works well. Im now very careful not to let it freeze.


I was pleased that e-trailer was the only place I found that had this replacement gauge for the Valtera water regulator. When I ordered it they told me the date it would arrive and it did arrive on that date.


Perfect replacement for gauge. Easy install. Restores use of Valterra Adjustable water regulator that evidently froze.


Removed the old one and installed the new one. everything went very well. just returned from a week in DC camping and it worked great. no problems. i would like to say that ETrailer is a good source for information as well as great, quality oroducts. i have used them for many years.

Great no issues


Product is the exact replacement of my water regulator kit used for my camper.

After 1 year I can say this gauge still work great. A good tip for Northern regions , dont forget to empty all the water before storing .


I have ordered a number of times from etrailer. Always good to deal with


Received the item in a secure package ready for use. Replacement for a unit that froze during a couple of cold nights. Original did not indicate the unit was liquid filled and should not be used in freezing temperatures. Now I know, and will remove during cold weather. The unit was originally purchased at a different retailer for a much higher price and would be a waste of money to just discard it without trying to repair, so online investigation brought me to etrailer for parts, good move, excellent service and excellent follow up on ensuring I received the part. Most definitely would purchase from them again.


use this product on a RV pressure regulator works great etrailer is a good place to buy Parts customer service is fantastic very knowledgeable people


I purchased a replacement gauge for the Voltera adjustable water regulator. The original was pegged on 160psi for whatever reason I don't know but the regulator worked fine. Replacing the regulator would've cost $60-$70 but just the gauge was considerably less. The product was delivered in a timely manner and etrailer had an answer within an hour after I emailed a question on the new gauge.


Needed this replace the original that stopped working. I believe it failed because of freezing. I won’t leave in the camper during the winter now. It’s a direct replacement for Valterra adjustable water regulator. Takes 30 seconds to install, it comes with Teflon tape applied.


Direct replacement for the failed gauge on my Camco ever water pressure regulator. Saved me from having to buy another $40 unit.


The pressure gauge arrived. The packaging did not show any damage however the gauge was reading 10 psi still in the original packaging.

It definitely should be reading 0 PSI while in the package. I will have our customer service team reach out to you.


Super fast shipping and just in time for RV trip. As other have mentioned, I forgot to take gauge out of rv over winter and froze. Rather than replace entire Valterra unit at twice the cost I went with just the gauge because of other reviews and worked flawless. Thanks.


Ah, the ordered replacement arrived safely in a timely manner.

Presently we are waiting for the weather to move the thermometer above the freezing point. Glad we obtained it midst the below freezing temperatures to have the replacement on-hand for the swap once the calendar progresses and temperatures adjust.
After that we will observe how the replacement functions.

At that time a different review can be shared.


It arrived 2 days early and in perfect working order. I installed and calibrated it and now have my RV water regulator working again.


I ordered this thinking it was the oil filled version. It's not, or at least the one I received is not. I replaced the gauge on my pressure reducer that was oil filled because after a few years the oil had leaked out of it. So, perhaps the non-oil filled version is a blessing in disguise. I've only used it once and it seems to be just fine. 4 stars only because of the non-oil factor, and that may very well be on me for not reading thoroughly. Valterra, the maker of my reducer, did recommend this part number. It fit perfectly and even came with the teflon tape applied so I only had to screw it in and test for leaks.


This gauge seems to be the weakest link in the Valterra regulator. My belief that this is correct was validated by a [online] employee. I am pleased that etrailer carries them so that I don't have to buy a complete regulator.


Replacement for my water regulator. Does the job.


Came quickly. Fits. Looks good. Pressure reading seems accurate. I’ve had it 3 hours.


This part is great to adjust the water pressure coming into the RV. Great tool, well worth it.


An exact replacement, has worked out fine for the year.


Product was reasonably priced and delivered in a timely manner. Guage replaced an existing one that got damaged over the winter.



Worked fine last year. Have not used it this year so far. Havent traveled anywhere yrt.


On time delivery &is what I expected



Still working
