I always assumed the small 20 lb BBQ and RV cylinders used back seating valves and I can find some confirmation and opinions either way but nothing from an official source.Miller Challenger 172Miller Thunderbolt AC/DC 225/150Miller Maxstar 150 STLVictor 100CVictor JourneymanOxweld OAHarris O/ASmith O/A little torchNo, that's not my car.
Reply:The propane type valves typically is all on so seat does not leak. But could have changed over the years to a better valve. You need to see if your valve want to be fully on. Dave

Reply:FYI I use the 20lb exchange tanks and have filled at the gas station. Exchange when the tank is out of date or the valves leak. Dave

Reply:I am not sure how much the ones I saw today at the exchange really were, the sign says 15# and the 20$ price sign was well scratched over. The supply hose finally sprung a leak after 25 years or so and I had nice chunk of copper line on hand to replace it.

Reply:This guy is probably more of a lesson in what not to do, but it doesn't appear to have back seating....

Reply:Why not call a place that provides propane to residential and industrial customers and ask them?? Or better yet, a company that makes the 20# tanks???

I was only wondering if perhaps one did leak a bit at the stem if back seating it would stop it. I have one now that leaks when opening but seems to stop when fully open, at least I get a big whiff when opening it that goes away once opened. It's very old and expired and is just about empty, will give it to Blue Rhino for a fresh one soon. |
