Flame King (KT12ACR-2a) 2-Stage Auto Changeover LP Propane Gas Regulator With Two 12 Inch Pigtails For RVs, Vans, Trailers

This product performs perfectly, with a straightforward installation process and excellent quality. I highly suggest it for anyone looking for a trouble-free propane setup!

I clipped this bad boy onto my RV setup and instantly felt like I’d leveled up my camping game. No more rushing to switch tanks mid-cook or wondering if my stove’s about to sputter out—this two-stage auto changeover keeps the propane flowing nonstop.Installation was surprisingly chill—just tighten the pigtails, hook up your tanks, and you’re ready to roll. I love how it seamlessly flips from one cylinder to the next without me lifting a finger, so my morning coffee and dinner grill-outs stay uninterrupted. The regulator’s solid brass body feels built to last, and those 12-inch hoses give me the perfect reach without kinking or fuss.Safety’s clearly a priority here, too—steady pressure means consistent flame control, and I’ve had zero leaks or weird pressure drops even on cold mornings. If you’re hitting the road and need reliable propane backup that handles the heavy lifting, this is your no-brainer pick. Trust me, it’s one less thing to worry about when you’re out chasing sunsets.

I found the installation to be a breeze with zero leaks. The price I got here was really good, making it a fantastic deal overall. Definitely a big step up from Camping World.

This was purchased to replace the original on a 2017 Airstream travel trailer. The quality seems at least as good as the original. It is a different design and is not a direct replacement, but it will fit and it functions the same. The installation is easy but was not a direct "bolt-in". I used the mounting bracket from the original and had to re-drill the mounting screws from the bracket to the regulator (apparently no industry standards on this). Sounds harder to do than it was. This "mod" allowed the unit to mount tighter and for the tank cover to fit.I am pleased with this unit and would use it again. No leaks or issues.The original unit isn't a great design because as the tank cover is installed it can easily hit the plastic tank selection knob and knock it off. This is what happened to my original and when I needed to switch tanks, I had no knob, Korbin!! Bad time to have no switch knob. This new unit appears to be less likely to have the same issue and is why I switched to it. I am not sure but I also think it was cheaper.To soon to know about long term durability, but again, the design should be less likely to be damaged by removal and replacement of the tank cover. This is probably more of an issue with Airstreams than other RVs.

The Flame King 2-Stage Auto Changeover LP Propane Gas Regulator is an excellent product! It’s incredibly reliable and ensures a constant, stable propane supply. The auto changeover feature works flawlessly, automatically switching tanks when one runs out, so you never have to worry about running out of propane unexpectedly. The included 12-inch pigtails make installation easy, and the regulator fits perfectly on my RV. Highly recommend this for anyone using propane in RVs, vans, or trailers—definitely a must-have for peace of mind on the road!

Sturdy and well-made definitely did the trick

I am extremely disappointed in this. We bought it last July when our RV regulator failed and started leaking propane. We installed it at the end of the season and didn't get a chance to test it out. This season when we went out to start our camping season the RV was not getting propane. After looking at the regulator the area that is supposed to change from red to clear/green was not changing no matter which tank we turned it to. Both tanks were filled that day so we knew that the tanks weren't the issue. We then had to try to track down another regulator to attempt to fix this issue which we couldn't do because of the time of day. We ended up spending the night in 40 degree weather with no heat. Once we did get a regulator the next day we ended up having to purchase one without the pigtails for the tanks, figuring we could use the ones off of the regulator purchased here.When we got the hoses off we were quite surprised by what we discovered. It appears that during the manufacture process the hoses were defective. Within both hoses the connection between the hose and the regulator was plugged. One side had an excess of red material which I'm assuming was used as sealant for the connection. The other side had a metal part blocking the opening between the hose and the regulator. This caused both feeds to the regulator to not function causing us the problem. I am quite surprised that during the quality assurance portion of the manufacture process that this was not discovered and I'm very disappointed.

Works like should. Have not had any issues. Though not a auto switch over, I did not want electrical power to basic devices. I live off grid and harness my own energy. I just use two 20lbs tanks for a stove and on demand propane water heater. Using this device for 2 tanks, over a year of use. I couldn't say for larger 60lbs tanks, but guessing this will work well.
