Canister Refiller -- Warning
I've been seeing a detail canister refilling device on eBay lately every bit a "MacCoupler Liquefied Gas Refill Adaptor Gas Charging Valve Inflatable converter" [sic]. This detail device is simply downright dangerous in addition to inwards full general should live on avoided. I'll explicate why I tell "in general" inwards a minute.
OK, thence what's incorrect amongst this refiller? Well, inwards representative you lot don't recognize the fittings, this refiller volition refill backpacking type gas canisters from a "bulk" propane tank.
Hey, forthwith doesn't that sound similar a slap-up idea? Hey! I tin receive got inexpensive gas out of my mass propane tank (like for a BBQ) in addition to refill my expensive backpacking canister. Pennies on the dollar! Sweet! What could maybe become wrong?
What could become wrong? A whole lot, in addition to it could live on bad, really bad. First, backpacking canisters produce NOT incorporate 100% propane. Standard backpacking type canisters inwards the U.S. of A. are rated at non to a greater extent than than 20% propane (mixed amongst 80% isobutane) or 30% propane (mixed amongst 70% butane). Propane is a really high pressure level gas. Put 100% propane inwards a canister rated for only twenty to thirty per centum propane in addition to what produce you lot get? Quite maybe a really nasty explosion.
Oh! I know! If my canister is only rated for twenty to 30% propane, I'll simply fill upwardly it upwardly to 20% of capacity in addition to operate out the residual empty! Duh! Problem solved.
Uh, non exactly. When combined amongst butane or isobutane, propane genuinely forms a blend. The resultant blend has a lower vapor pressure level than 100% propane. Odd every bit it sounds, you'll genuinely receive got less vapor pressure level inwards a canister amongst 20% propane in addition to 80% isobutane than a canister 20% amount amongst propane alone. Besides, what adept is a canister you lot tin only fill upwardly to 20% of capacity anyway?
Basically, you lot should never fill upwardly a backpacking type canister amongst 100% propane.
But what if you lot filled a canister to 80% of capacity amongst butane first? If you lot filled to 80% of capacity amongst butane starting fourth dimension in addition to were exactingly careful well-nigh non exceeding the overall rated capacity, in addition to then maybe this adapter would live on safe. I'm non maxim that it is safe, I'm maxim that there's the possibility that the adapter might live on condom -- from the perspective of the mix of gasses. The adapter mightiness nonetheless receive got other problems inwards damage of materials, design, in addition to construction. The really fact that someone pose a unsafe refiller similar this together suggests that they genuinely don't know well-nigh gasses. I receive got NO confidence that such a someone has the powerfulness to build a refiller that is condom inwards other respects. I'm sure non tempted to purchase one.
Putting it into perspective
Now, am I simply a "Nervous Nellie?" Maybe this is genuinely pretty safe, but you lot know this is modern society, in addition to nosotros receive got to protect people from themselves, don't we?
I submit to you lot that I am no Nervous Nellie. I refill my backpacking canisters all the fourth dimension (with butane!!). I purpose a windscreen amongst my upright canister gas stove. I sometimes purpose my stove within a tent. In other words, I produce all sorts of things that manufacturers tell us non to produce lest doom in addition to disaster overtake us. I produce things similar refill, purpose a windscreen, in addition to create within my tent because I've studied the objective dangers in addition to institute them reasonable for a someone who is careful in addition to has an agreement of how to mitigate the dangers. But I volition NEVER fill upwardly a criterion backpacking type canister amongst 100% propane. It's simply every bit good dangerous. Period.
This refill adapter is: NOT recommended (in the strongest possible terms).
I give cheers you lot for joining me on unopen to other Adventure In Stoving.
