LPG bottle dust cap

Have you tried the people who fill them??

As said, anyone who fills gas bottles sells them, particularly camping shops.

Its because they come loose that you LOSE them. They come with a retainer strap on them usually.

try BCF that's where I got mine last year

I modified a couple of old POL brass male fittings. Added a short chain attached to the bottle.

Search for Gas cylinder valve safety plug. They are available from CAMEC and Caravans Plus for less than $10. Have also seen them at BCF, Ray's Getaway, Kmart etc in a 2 piece blister pac.



Model available from CAMEC

MOdel available from Caravans Plus

I often have a chuckle about those cheap plastic plugs,
LPG at 54 deg exerts a force of 1794 kpa.
They should be brass with an oring.

Seems everything has got cheap and nasty ..... and they still want to hit you up top dollar.

Some years ago it was possible to buy a fairly decent plastic screw in bung with a decent knurled knob that you could get decent a hand full of ... and they came with a piece of chain attached.

Now as has been mentioned the swap and go gas refillers are required to fit one every time they fill a bottle.
The bungs they use will probably cost them 50cents or less as they consider them disposable.

Champagne corks work ok.
Once you've emptied the bottle of course.

Buy a role of masking or electrical tape and use that.

Anaconda ad Gameco both sell them

My small bottle (about 3kg) has a POL with threads on the outside - which holds nicely a chair rubber end cap e.g. https://www.bunnings.com.au/tic-10mm-round-white-rubber-external-chair-tip-4-piece_p4050056 I'm not sure if all POLs are the same size, & not sure what size cap I bought - though there are plenty available & in black or white.

Gas plug - pick them up at Bunnings for bugger all - no thread - just push them in - never had one fall out.
