I never knew propane would attack the inside of any rubber hose. Thanks for sharing the info OP
A warning and an advice to those using a 20 lb propane tank for their BenchSource

Benzomatic touches are built for unregulated pressure . When you put a hoes on them you can have a regulated pressure or you can hook it up direct . Mine I have hooked up direct. With the proper hose . It is the same hose that is used in the trailer that hooks the tanks to the regulator . Larry
Since you know so much about this, so please tell us what is in fact the difference between a hose for propane use which is the gas and hose I am using, and a hose for LP gas?
Pressure rateing and design it could have a nylon Linner But the construction and for pressure . Larry
I don't see pressure having anything to do with what is causing the clogging of the torches. As for the liner, we both can only see the outside and AFAIK, both can be rubber, the inside liner I cannot see or know. I mean are you guessing that the liner is different or know they are different?
I don't care what is made with . The LP gas company made it . I have to asume they know . Larry
Hmmmmm..... I suppose you call that proof! Wow!
The hose you bought is fine, made for this or other applications. My opinion, no proof, leaving gas in the hose may have let it warm too much and gel or solidify some. Gas in an LP tank is cold coming out. I have the same setup but turn valve off at tank and let flame die, then slip sandwich bags over the ends when I disconnect, no problems in 5 years.
Thanks milo-2! That’s pretty much my thought i.e. the hose is fine and made for our use.
The idea that leaving high pressure gas in the hose dissolves some material that deposit on the orifice of the torch is not something I made up. It’s basically what the tech at Benzomatic told me (anyone can call them to confirm). FWIW, it also made 100% sense as I have used it as you which is to close the main valve at the tank and run the torch dry by burning what was left in the hose – NO problem for months. The ONE time I decided to leave pressure gas in the hose (with both main valve at tank and torch close), the torches immediately clogged up i.e. BOTH torches the next time I try to use it. This was no accident but exactly as described by the tech who I assume have seen more of this than all of us put together. You think?
The fact I could clear it with acetone also fits the above reasons.
I don’t see ANY problem with this and I have NO concerns about this but the ONLY REASON I posted was because I thought I would be a nice guy and pass my learning on to other folks so that they don’t have to relearn my mistake. But well as they say “no good deed must go unpunished”….
Getting crap when you are trying to pass on useful information makes me wonder if I ever want to bother to do this again - sorry but just a little tired of the idiots on this board....
I'm a little late to this clam-bake but I had a trailer set for a complete Colorado winter while I lived in it. Furnace ran almost continuous and the Propane delivery guy dropped off a couple hundred gallons every 3-4 weeks. The "Hose" that the LP Gas company made up for me was never de-pressurized. Burners never clogged in stove or furnace either.
I do know that the guy who hooked up the hose did blast some propane through it before making the final connection. Any dust, rubber, bat guano, or BS, was blown out so it WOULDN'T plug any orifices.
LP Gas lines, Nat Gas Lines, Hydraulic Lines, all benefit from a good "blow-out" before connecting and placing in service. Either that or put a "strainer" in the line just before point of use.
BTW, the CS rep at the "Torch Company" is most likely the only guy at the factory that can carry on a conversation without using lots of "offensive" words so they put him on the CS desk. Doesn't mean he really knows what he's talking about.

I would go that far but close . But with pressure left on the clog only came from what was inside the hoses or from the shutoff valve in the torch head . Larry
This "common sense" practice is more likely than not, a learned practice. I shut my gas off based upon experience of coming out to BBQ and finding the tank empty. Small leak in the hose and gas gradually escaped. Many folks dont turn off the valves after the gas burns off. Seen more than one fireball from someone lighting a stove with gas already on.... You would be surprised how many people end up dead because they use a gas BBQ to heat their home when the power goes out. The right way to fry grasshoppers is common sense in Africa, but I don't think I could do it correctly.....
Imagine one of our long passed grandparents suddenly waking up in a WalMart Electronics section. How much of our "common sense" electronics would make sense to them?

Not all lessons have to be learned the hard way. Stopping and thinking for a minute or two about the risks and hazards associated with something as simple as using a BBQ or any other propane device can help keep a person safe if they have half a brain: ie;
Im using a highly flammable pressurized gas. Ok, what could go wrong? Where could I experience a leak? How do I completely isolate the gas in the tank to avoid a leak? How do i get rid of stored energy (Gas in lines) to eliminate that hazard? It really is common sense.
For those without the gift of common sense (which seems to be less common these days) and the unwillingness to question the things they don't know, well I suppose Mr. Darwin will eventually take care of them. Lol
