That is the pressure range that is expected inside a propane cylinder under normal circumstances.

"According to the national standards publication NFPA58, a propane tank with*20 pounds*(5 Gal) of gas at 70°F would have a pressure of 145 psi; at 90°F, pressure would increase to 180 psi; at 105°F, pressure continues to rise to 235 psi, and at 130°F, pressures of 315 psi would be reached."

Hose clamps on a barbed fitting is perfectly capable of holding that kind of pressure, provided the hose is rated for that pressure.

Of course when you are transferring propane from one tank to another the pressures equalize between the tanks, then the liquid transfers like pouring water. At that point you are relying purely on gravity to do the transferring. If it is a hot day the pressure in the tanks can be quite high.

Liquid propane is not low pressure. The only reason it remains in liquid form is BECAUSE it is under pressure. At atmospheric pressure propane boils at -42°C.

Then refill the empty at your earliest convenience. One regulator, one solenoid w/ remote switch.

Yep, if I were in Westchester I'd just run out and pick up a lay down tank and anything else I needed.
I'm not, and even worse I'm stuck in this damn pandemic. Therefor, I'm trying to make do with what I have, 'cause I'm not going to get anything else any time soon.

Do you have access to any hardware? Where do you get your gas refills from?

We pay a guy ec$5.00 to put them on the ferry to Grenada and they get filled down there and then returned to the boat.
There are a few hardware stores here, but they about equal one aisle of hardware items in an Ace hardware in the US.

That is a challenge!

I am not familiar with the type of fitting on your tanks, and it is impossible to tell without removing the regulator. You need to identify the connection type, and then you should be able to get an adapter hose made up and shipped to you. It might get a bit expensive though!

Thanks, but I think I have my answer and I'm just going to have to find a work around w/o trying to import anything at this time.
I do appreciate your information about the pressures, etc. That will help.

Re: Propane regulation

A bit off topic, but I recently spent a week aboard a mate's 34 footer built in the late 1970's, with a gas bottle in a drained locker at the back of the cockpit which had to be turned on at the bottle every time you wanted to use the stove (2 burner plus oven plus grill on gimbals). There was a big notice in the galley saying turn gas off at bottle when not using stove.
I can't tell you how nice it was to have such a simple system with no electrics involved anywhere. The inconvenience of having to turn the gas on and off at the bottle each time, was an absolute joy in relation to the security it gave.
I'm going back to it in my own boat! Simplicity is what I crave most of all these days.

Re: Propane regulation

No gas detector in the cabin.
That’s where the stove and burners are. A leak in there from the hose or fitting will blow up the boat.
Not very safe I think. Please reconsider.😀

I am a bit confused. Why can't you use a single tank... which you presumably have... add a solenoid controlled from galley and use your present regulator. When that tank is empty remove it and connect the spare???

My drained propane locker has only room for one 10# tank. The spare 10# tank lives in the anchor locker which is also drained. It's not a hell of a lot of capacity... but I've never run out of propane. As soon as do the switch which take 10 minutes... re fill is on my to do list.

Yes where I am not it is easy to get a refill. I can also use the small 1# tanks as emergency spares... and when I kept then they lived on the shelf in the propane locker.
