## Description

The Auto-Changeover LP Regulator allows you to hook up 2 Propane tanks and the regulator automatically switches over to the second tank once the first one runs out (and vice versa). The indicator changes color to let you know when a tank has been depleted and needs to be refilled. The inlet is a 1/4" SAE inverted flare and the outlet is a 3/8" NPT female. Also included are 2 of the 12" pigtails to connect the regulator to the propane tank or propane supply.

Review: Review of RV Automatic Propane Tank Switch Over Regulator - Having used the RV Automatic Propane Tank Switch Over Regulator during several camping trips, I am thoroughly impressed with its performance, especially in extreme weather conditions. The regulator’s ability to automatically switch between two propane tanks is its standout feature. This ensures a continuous supply of gas, eliminating the need to manually change tanks, a real convenience during my travels. The indicator, which clearly shows which tank is in use and when it’s time to refill, is a practical addition that I found extremely useful for maintaining a hassle-free propane supply. Installation was a breeze, and the build quality of the regulator is commendable – it feels sturdy and reliable. Whether it was for heating or cooking, the regulator adapted to different propane demands without any hiccups. One of the most impressive aspects of this regulator is its performance in bitterly cold weather. Unlike some other models, it operated flawlessly, maintaining a consistent gas flow even in freezing temperatures. This reliability in cold weather is a significant benefit for anyone who loves winter camping or lives in a colder region. Overall, this automatic switch over regulator is a top-notch accessory for any RV owner. It brings convenience, reliability, and peace of mind, enhancing the overall camping experience. For those looking to simplify their propane management, this regulator is an excellent choice.

### ⭐⭐⭐⭐⭐ Perfect Replacement For My Travel Trailer Regulator
*by W***W on November 9, 2024*

This is the second time I had to replace the regulator on my 2017 travel trailer. The first time was because of the mass recall. I had to figure out the regulator I needed based on total BTUs, figure out the length of pigtails and ensure the handles were the color I needed (dark green for most trailers), find / buy a bracket to mount the regulator to so it would stay on the holder, figure out the right self-tapping screws to get to mount the regulator to the bracket, and then get Teflon tape rated for propane. After all that work, and spending a lot more money than I did on this one, that regulator didn't last. So I found this one. Affordable. 12" pigtails with dark green handles. Bracket included. Auto-switching. Empty tank indicator. Enough BTU throughput to handle my trailer twice over. I changed the regulator out in less than 5 minutes and then tested it. The step that took the longest was cleaning the old Teflon tape off the threads. Easy. This regulator works like a champ. Thanks.
