Product Details

The small butane gas cartridge (also known as canister butane gas or portable butane fuel canister ) is a common portable fuel, widely used in small gas appliances such as camping stoves, portable hot pots, and spray guns.

Operating manual

Confirm equipment compatibility

Ensure that the stove or equipment you are using supports the butane gas cartridge (usually in standard screw or snap-in interface). There may be minor differences among different brands, so it is recommended to use the original factory or certified compatible gas tanks.
Installing the butane fuel canister

Insert the cartridge gas canister vertically into the slot at the bottom of the stove. A "click" sound indicates that it is securely fastened.

Some equipment requires rotation for locking. Please follow the instructions for operation. Before installation, check if the gas cylinder valve and the stove interface are clean and undamaged.
Ignition Usage

Open the gas regulating valve of the stove, then ignite (it is recommended to use an electronic igniter or a long-handled lighter). Adjust the fire intensity to the desired level. Avoid burning at the maximum power for an extended period.
Replacement and Disassembly

After use, first close the gas stove valve and wait until the flame is completely extinguished before removing the gas cylinder.

If the gas cylinder is not fully used up, it should be stored properly. Ensure that the valve is tightly closed and store it in a cool and ventilated place.

Safety precautions, Prohibit the following actions

√ It is prohibited to use in enclosed spaces (such as vehicles, tents, small rooms) to prevent carbon monoxide poisoning or gas accumulation from causing an explosion.
√ Do not store near open flames, high temperatures or direct sunlight. The gas cylinder may expand or even explode when heated (butane has a low ignition point, it can vaporize at approximately -60℃, but the pressure increases dramatically under high temperatures).
√ It is strictly prohibited to puncture, burn or forcibly dismantle empty tanks, even if there may still be flammable gas remaining inside the "empty tank".
√ Do not use upside down or at an angle (unless the equipment explicitly supports it), otherwise it may cause liquid butane to spray out, leading to a fire.
√ Prohibit children from coming into contact with or operating.

The storage time for butane fuel canister of this type is subject to certain limitations.

The official and industry consensus is: a safe usage period of 2-3 years.

Most gas manufacturers, fire departments, and outdoor safety guidelines state:

For cartridge gas tanks (butane gas cans), it is recommended to use them up within 2 to 3 years from the date of production.

Even if not opened and in good appearance, there are safety risks after more than 3 years, and continued use is not recommended.

Reasons:

The sealing ring of the tank (made of rubber or plastic) will age over time, resulting in minor leaks.

The internal pressure may change due to material fatigue or slow gas penetration.

Poor storage conditions such as high temperature and humidity will accelerate the aging process.
Some materials mention a "10-year shelf life"? Be cautious in your understanding.

A few materials state that "the shelf life of the cartridge gas tank is 10 years", which usually means:
The theoretical design life of the tank as a pressure vessel (for example, if the carbon steel tank itself has strong corrosion resistance);
The prerequisite is annual professional inspection and proper maintenance (such as drainage, rust prevention) - but this applies to industrial fixed gas cylinders, not to one-time portable butane gas cartridge.
✅ Current situation:
The vast majority of gas cylinders in the market are disposable and non-reusable consumer products. They do not have an annual inspection mechanism, so they cannot be treated according to the 10-year standard.
How to determine if it has expired?

Check the production date on the bottom or the body of the container (usually indicated by a barcode, such as "20240815" which means August 15, 2024).

Calculate the time:

If it has exceeded 3 years, even if not in use, it is recommended to stop using it.

If it has exceeded 5 years, the risk significantly increases and it must be scrapped.

Inspect the appearance:

Deformity, rust, deformation of the interface, abnormal odor (butane should have no smell; if there is an odor, it may be due to the leakage of a warning agent added) and so on, stop using immediately.
Safety Storage Recommendations (To Extend Lifespan)

Store in a cool, dry, and well-ventilated place, with a temperature below 40℃, and avoid direct sunlight.

Keep away from fire sources, power sources, and heat sources (such as heaters, stoves).

Store upright and do not invert or lay horizontally.

Do not stockpile in large quantities. Follow the "first in, first out" principle.
What to do with expired gas cylinders?

Do not puncture, burn or throw them into regular trash bins by yourself!

You can contact local hazardous waste recycling centers, gas companies or fire departments to inquire about professional recycling channels.

If there is still gas in the cylinder, you can connect it to a gas stove and slowly release the gas in a safe and ventilated area (do not ignite, just open the valve to exhaust), then flatten and recycle it (some communities allow this).
