The only shell weight on this shelf
Perune L100-2 all-season mix, 100 g (3.5 oz)
A hundred grams of gas in a 198-gram canister, with the mix published as 72 per cent isobutane, 26 propane and 2 other — the only listing here that admits a remainder.
On the maker’s own page
An iso-butane camping fuel gas canister, all-season mix, 100 gram, two-pack.
Perune states a clean-combustion all-season fuel mixture, best for backpacking,
designed for use with Perune portable stoves and cooking systems and fitting
inside all Perune Travel Pick & Carry cooking systems; canister materials steel;
a canister weight of 7.0 oz; dimensions of 3.5” × 3.5” × 2.7”; and a gas mixture
of 72 per cent isobutane, 26 per cent propane and 2 per cent other.
No valve type. No resealable statement. No bullet points at all.
Ninety-eight grams of steel
The only shell weight on this shelf.
Seven ounces gross is about 198 grams. The gas is 100. So the canister itself is
about 98 grams — very nearly as heavy as the fuel inside it.
This shelf’s introduction says the gross weight includes a steel shell you also
carry. This is the only listing on the shelf that lets the figure be worked out,
and it explains why a 230-gram canister is lighter to carry per gram of gas than
two 100-gram ones.
Seventy-two, twenty-six and two
A mix that adds up.
The other two listings here that publish proportions both give 75 and 25 — a
round hundred.
Perune gives 72, 26 and 2 per cent other. What the remainder is, the page does
not say; that it exists is the honest part. A gas blend is a mixture, and the
small balance is usually n-butane or a trace from the separation.
This shelf’s introduction makes the mix the cold-weather variable: butane-heavy
mixes lose pressure as the temperature drops.
And no valve
On the shelf where the valve decides everything.
This shelf’s introduction: nothing else in camping kit fails on compatibility as
bluntly as a gas canister, because the wrong valve simply will not go on the
stove. Three systems share this shelf — EN 417 threaded, bayonet, and pierceable.
This listing names the maker’s own stoves and no fitting. Two canisters here name
EN 417; two say screw-on; one is a notched-collar cartridge.
This shelf’s buying tip is the answer: check the valve wording in the stove manual
before ordering.
Three dimensions for a cylinder
Three point five by three point five by two point seven.
A cylinder has a diameter and a height. Three figures is a bounding box, from
which the diameter is 3.5 inches and the height 2.7.
That still makes it the shortest and fattest canister on this shelf — which is
what decides whether it nests inside a pot, and the listing says it nests inside
the maker’s own.
Perune’s own instructions on the canister carry the handling. Nothing here
replaces them, and nothing on this page describes any product as safe.
