Do you wish to contact us about one of our Useful Blogs? You may want to tell us about a business that tests of out-of-date gas bottles for example – one we don’t already list on https://gasbottlerefills.com/gas-bottle-retesting
Remember – this website was designed primarily for those with POL-fitting LPG gas bottles. Those using ‘Primus’ type cookers with a 3/8″ BSP (British Standard Pipe) fitting, will need to carry a gas-filling adapter https://www.snowys.com.au/gas-cylinder-adapter-38bsp-lh-to-pol Very few gas bottle refillers have one as there is so little demand.
As for backpackers – you are more likely to prefer those tiny lightweight butane cookers. They are cheap and readily available in all supermarkets as are the gas cans for them.
