WADEO 12 FT Propane Extension Hose with Gauge, Leak Detector, Compatible with QCC1/Type 1 Connection, Universal for BBQ Grill, Heater, Gas Generator, Black, Rubber & Brass Construction

Goes right on to our 100 pound propane tank and then into the standard propane hookup for our RV. The gauge works well and it makes it much easier to tell when we are getting low. Highly recommend to those who are tired of putting bottles in and out of an RV.

Worked very well as an extension for blowtorch roofing work. No issues.

Works perfectly so far but it's only been a few days. Bought it to use one of the tanks on my camper to cook with on my grill and camp stove instead of lugging an extra cylinder every trip. Accidentally left the tank valve on twice, no leaks thus far. Would be 5 stars but we'll see how long it lasts.

I have a torch from Harbor Freight, came with a six foot hose. Too hard to cover any distance, this extension is perfect. I don't know that it detects leaks, but that isn't what I bought it for, my nose says if it's leaking or not

I bought this extension hose along with an adapter to allow me to connect a propane generator to a 100 pound propane tank. The connection worked well. The generator started right up as expected and no leaks. I turned off the propane valve and let the generator run to depressurize the line. As the line depressurized I watched the gauge on the propane line drop from green to the lower peg. It's clear this measures propane level by pressure. I think it will be useful for letting me know when the tank gets low and it's time to refill the propane tank.
