Propane adapter

Head_Hunter

Does anyone think this will work safely?

gungun

is there any way of telling when the small can is filled?

edit: ah sorry says filled in less than a minute but still...

Frank the Manc

excellent find.

in principle its no different to refilling a mag, whether or not it would need to be regulated though i don't know.

only one way to find out.

it is believed that the explosion in Vistakon (johnson & johnson) plant in Limerick some 4 years back was caused by filling a Propane cylinder from a larger cylinder
the damage to the building walls and roof was extensive and cost inexcess of 30 Million not to mind the loss of life to the person involved

Have that adaptor, but it wont fit Irish/EU tanks, only US ones, though the bottle still fits.

In filling gasses the general rule is only ever to fill to 80%, that is 80&% liquid, 20% gas. If you were to fill to 100%(Not that you would likely be able) a degree or two and the can would blow up, if it were not for the safety valve on the top beside the neck.

Its not safe to fill them unless you can be sure of how much liquid propane you're actually filling into each bottle. Some have reported just opening the valve for 1 second, but thats not exactly a brilliant idea. The only method I can see is weight, but that would be a pain to measure.

Huh, I wont be buying one having read that tbh.

mm, That device is for filling normal propane bottles, from a large tank of propane... NOT remotely useful for airsoft.

There are much more aplicable, simpler ones... The Airsoft Inovations propane adaptor fits to a small can of propane, then allows one to fill mags... Its the same as green gas, but without the lubricant (you can add it yoruself to the mag with a can of silicone oil)

The can of propane lasts about 5 times as long as a bottle of green, costs about half the price, and works perfectly fine. I've been using it for years now... big money saver.

yea there is,i seen it in one shop in dublin,they who must not be named stock them

400g = 15 quid. 11Kg = 30. Refilling would be worthwhile if it could be done safely.

Jebus, go to a builders merchants... its much cheaper than that... I buy the 400g ones for about €5 at a builders yard.

Asked last time we were in Brooks, didnt have any.

I'm not really up on trade wholesalers though. Suggestions? Preferably in south Dublin:)

Firekitten

Not been around any in south dub, could try Chadwicks?

Have one of them at home, never did get around to testing it.

It's the same principle as how I fill my co2 tanks for the escort mp5, but the refill setup I have for that has the small tank on a flexible hose that means I can hang the tank out of a weighing scales so that I know how much liquid has gone into it and when to stop, as someone pointed out above, you never, ever fill to full capacity, my 16oz tank I'd normally go to about 12-13oz, never higher.

I think you can get the large tanks with the correct fitting over here, but without some method of measuring how much liquid is being transferred, it's not safe.

Incorrect.

It was an acetylene cylinder and if I remember correctly there was no flash arrestor fitted but I'm open to correction on that last bit.

Nothing at all to do with filling a cylinder as this operation would not have taken place in the area the accident happened in (or anywhere on the plant for that matter).

The acetylene was being used as part of an oxy-acetylene welding /cutting set by contractors on-site.

The unfortunate accident happened 19th March 2004.

Sorry for dragging off topic but felt I had to post an accurate account of what happened for this incident. Now back onto topic...

One thing to always consider when filling gas from one vessel to another is the working pressure and the test pressure of the receiving vessel as well as the valves and interconnectors.

The third party cylinders mentioned in the ad linked to by the OP typically state on them that they are not re-fillable. As such I wouldn't advise re-filling them.

The only cylinder I would consider re-filling would be one that is certified acceptable for the gas, has a current hydrostatic test, visual test and has the appropriate valve fitted.

If in any doubt don't transfer the gas.

no wish to cause an arguement but some where between your facts and mine lies the truth
i had no wish to go into all the details on a public forum
our company also had some people on site at the time of the accident
but in fareness to the person memory who sadlly lost his life we should maybe let it rest

i wholeheartly agree with you about the dangers of Oxy/acetelyne equipment
had the missfortune to have a hose ropture next to the regulator on me many years back
thankfully the flashback arrestors worked that day as they were ment to do
burned my hand badly still have some of the marks to prove it

My advice to all here Dont Do IT

I worked at the plant at the time.

Like I said, I'm not 100% certain at this time as to the exact cause of the accident (I seem to remember a flashback arrester being of concern at the time) but I do remember clearly that no gasses were being transfered from one vessel to another at the time and it was the acetylene cylinder that was what went bang.

Not wishing to get into any arguement at all on the issue , I was merely pointing out that gasses were not being transfered.

Definately back on topic again...

where do you get the propane and do you use an adapter
