  • Easy Install
Size: Regulator with 12-inch Pigtails
Exact fit for my rv, mounted between two tanks. Feels like good quality materials and performed well on our first trip with the regulator. Arrived quick and has simple to understand instructions.

  • Reliable LP Propane Regulator
Size: Regulator with 12-inch Pigtails
The auto changeover LP propane gas regulator works perfectly! It switches smoothly between tanks and provides a steady gas flow. Easy to install and highly reliable. A great purchase!

  • Great product
Size: Regulator with 12-inch Pigtails
This was perfect and worked perfect. The bonus was not having the buy the hoses separately. And the price is awesome.

  • Plastic valve nuts
Size: Regulator with 12-inch Pigtails
Happy with the regulator. Works as intended. However, the plastic nut for the valve fitting broke on one of the pigtails so we had to buy a replacement. We've only had it for 4 months and it's been protected by a dual tank cover so no exposure to sun. Not impressed with this.

Size: Regulator with 12-inch Pigtails
Had a leaking propane regulator on my trailer. Purchased this regulator and installed it in less then 5 minutes. No leaks and works as advertised.

  • Excellent customer service!
Size: Regulator with 12-inch Pigtails
I received this very quickly which was great since my propane is my source of heat! Very easy to install. After 3 months it began to leak and it was a few days past the return date. I contacted the company and Mendel replaced it immediately! Originally I thought it was one of the hose connectors that was leaking so that’s what he sent me. But it was actually the body of the unit and when I contacted him again he immediately sent the whole unit to me! Great customer service I highly recommend them and will use them again when necessary. ... show more

  • Easy to use
Size: Regulator with 12-inch Pigtails
This is very easy to install except they’re to cheap to add a small roll of plumbers tape to insure the there’s no leakage from the main hose to the regulator. So before you install it pick some up at a hardware store before installing. Other than that it’s working perfectly. May update later after using it for a while. I only installed it 2 days ago. ... show more
