Propane or Mapp gas

I think the primus threads are M14 x 1.5mm

Thanks very much @optima21 I think you are right. Trouble is I can't seem to find any adapters that convert that into something I can use to refill my cylinder

i use a blowtorch that fits the primus bottle and took the burner of the end and screwed it in to a bullnose that i re drilled and taped to suit here it is they have put it on home made tools .net https://www.google.co.uk/search?q=propane++refill+adaptors+home+made&sxsrf=ALiCzsY-V-sjvVXToHMddxUuh-o6WPCXgw:1655922249248&tbm=isch&source=iu&ictx=1&vet=1&fir=UnNERHmKcc4fcM%2CAXbBB7a2sFTHkM%2C_%3B0shhYKLn-tDqnM%2CgaNBetCTQ9xSlM%2C_%3B8AzIlY8v8VJH5M%2CanytZOeMJvYHYM%2C_%3BG3ZFuy5QRMU1WM%2CG8GwOW14vmB54M%2C_%3BNRTRVWt78iJ8GM%2Ctkic-DVpNCIq-M%2C_%3BaY6Mhu5s7wjlbM%2CgaNBetCTQ9xSlM%2C_%3BMAdkbvH3ZRfBiM%2CgaNBetCTQ9xSlM%2C_%3B2oYS7R7ccYumPM%2Cv1LeWYnF6LoBdM%2C_%3B3xjQ2uju-jMcHM%2CAgyhoIckGr8_NM%2C_%3Bn8fMY05k7jfy9M%2Cv1LeWYnF6LoBdM%2C_&usg=AI4_-kTlxc7GIGUipTA1lLtMkNyFx8uEYQ&sa=X&ved=2ahUKEwicscSL18H4AhXBnVwKHckzAa0Q9QF6BAgcEAE#imgrc=UnNERHmKcc4fcM if you make one take the one way safety valve out of base of torch it just scews in or it wont fill

Hi @brightspark Your solution looks perfect although a bit beyond my abilities unfortunately. It did make me think though.... I have a calor gas bottle with a regulator and a hose going to an old BBQ. The blow torch attached to my bottle has no holes in the side so was wondering whether fitting the hose onto the blow torch and filling it that way would work? May need to clip it on or maybe create something to adjust the hose diameter but would at least be something I am capable of if it would work.

Thanks

Lee.

HERE is a link that works!

Thanks @northwest It says it is for US gas bottles. Will it work with UK bottles do you know?

 

[brightspark]

what bottles are you going to fill with it

 

[leenowell]

The blow torch has a Primus 2000 bottle and was hoping to fill it from the gas bottle I have attached to my BBQ

 

[leenowell]

Hi @brightspark any thoughts on my "mad" idea of replicating your approach to fill the Primus 2000 gas bottle from a calor gas bottle using the blowtorch but connecting the 2 via the gas hose instead (I don't have the skills to replicate your actual approach)

[leenowell]

@northwest I checked with the supplier of the adapter you posted to check it fits UK calor gas bottles (it says US) and the Primus 2000. Is this definitely the one you bought and confirmed it does fit?

 

[northwest]

It fits MY bottle so whether or not it fits yours is for you to decide. It worked perfectly for me yesterday too as I filled my gas bottle up for my hand held torch.

Got screwed the other day for £21 for a small gas cylinder replacement. Thought it time to try out the bottle filling gadget, done two and they both ended up the same weight as the new original at .9kg, takes about an hour with the big cylinder inverted.

the newer map bottles wont fill as they have a 1 way valve in them. the primus 2000 refilable are easy and can be filled 10 minutes

Not sure about that BS, one was an old cylinder thats been kicking around for a while the other was less than a month old, both filled the same.

£21 for a small one

I keep meaning to look into bigger/proper size propane bottles. Where does one buy them and how much should it be with gas?
And do they do propene/map replacement?

i can just use a cheap primus torch take the one way valve out of it buy a bulnose. drill and thread it on to the torch

use a 19kg propane bottle to fill em its cheaper to fill than the 15kg

 

[optima21]

I think Im correct these days, but we arn't supposed to talk on here about refilling gas bottles as it may be unsafe and we dont want to set a bad example.
