Gas cylinder threaded 100 g all-season, butane-isobutane-propane, EN 417 thread, from −23 °C

Threaded gas cartridge 100 g, all-season, butane-isobutane-propane — the smallest cartridge with 7/16″ thread to EN 417 standard for tourist burners, lamps and heaters with threaded attachment. A mixture of 50% butane, 25% isobutane and 25% propane works from −23 to +35 °C: winter overnight stay, morning tea in frost, high mountains — the cartridge doesn’t “fail” like pure butane. 100 g of gas is 25–30 minutes at full power of a 3 kW burner or 40 minutes at 2 kW: 3–4 boilings of half a liter each, that is one day of solo hiking or a spare cartridge in your backpack pocket. Steel body Ø 90 × 70 mm, gross weight about 195 g, protective cap. Disposable, not designed for refilling.

Thread standard — for compact tourist burners that screw onto the top of a cylinder; household stoves and burners with a collet lock do not work with it — for them there is a collet cylinder 220 g. The same gas in larger threaded cylinders — 230 g for weekends and 450 g for a week or group. The 100 g cylinder is chosen when weight and size matter: it fits inside a 0.75–1 l pot together with the burner.

For whom

• Ultralight tourists, runners, cyclists: burner and cylinder in a pot, 300 g for the entire kitchen
• Fighters with threaded burners: spare canister in a pouch for tea and heating
• Climbers and winter hikes: all-season mixture with propane works in frost and at altitude
• Day trips, fishing: one canister — morning coffee and lunch
• Emergency backpack: compact gas supply for a compact burner

Benefits

• All-season mixture with 25% propane — works from −23 °C
• 7/16″ EN 417 thread — fits all threaded burners, lamps and heaters
• 100 g — 3–4 boils of half a liter, 25–40 minutes of burning
• Ø 90 × 70 mm, gross weight about 195 g — fits inside a pot together with the burner
• Self-closing valve — you can unscrew an unfinished cylinder and screw on another
• Steel body, protective cap on the valve

Instructions for use

1. Make sure the burner regulator is closed. Remove the cap from the cylinder.
2. Place the cylinder vertically with the valve facing up and screw the burner clockwise until it stops — without effort, the thread enters freely. Do not tilt.
3. Open the regulator, ignite the burner according to its instructions. Hold the cylinder vertically; on uneven ground use a stand with “legs”.
4. After use, close the regulator, let the burner cool down, unscrew the cartridge, put on the cap. The self-closing valve retains the remaining gas.
5. Dispose of empty cartridge with metal; do not throw into fire, do not puncture.

In winter, keep the cartridge in your pocket or sleeping bag before cooking: a warm cartridge provides full pressure immediately. During operation, the cartridge cools down — this is normal; if the flame weakens, take a break or warm the cartridge in your palms, not near the fire.

Safety

Pressurized cylinder, gas is extremely flammable. Do not heat above +40 °C, do not leave in the sun, in a car in summer, near a stove or heater; do not cover with a windscreen that reflects heat onto the cylinder. Do not puncture, disassemble, or burn even when empty. Do not refill. Change the cylinder only on a cold burner, away from fire; when changing, brief gas release is possible — do not do this near an open flame. Use only with devices with EN 417 thread and only in a ventilated place — combustion produces carbon monoxide; do not cook in a tent. Store vertically, with a cap, away from fire, sparks and heating devices, out of reach of children.

Frequently Asked Questions

Threaded or cartridge?
Threaded — for compact tourist burners that screw onto the top of a canister, lamps and some heaters. Cartridge 220 g — for household stoves in a case, folding burners and attachments. Check your device: 7/16″ thread — this canister, lever lock — cartridge.

How long does 100 g last?
For 3–4 boils of half a liter: a day of solo hiking with coffee in the morning, lunch and tea in the evening. For a weekend take 230 g, for a week — 450 g.

Does it work in frost?
Down to −23 °C thanks to 25% propane and isobutane. In frost, keep the canister warm before use; during operation it cools down — if the flame weakens, warm it in your palms.

Can you unscrew an unfinished canister?
Yes, the valve is self-closing: unscrew it — gas doesn’t escape, put the cap on, save it for next time.

Will it fit a burner with an adapter for a collet?
Yes, if the adapter is for EN 417 thread; but the burner doesn’t become more stable from this — on a 100 g canister a tall pot tips over, get a stand or a larger canister.

Can it be refilled?
No. The canister is disposable, the valve and body are not designed for refilling.
