A butane lighter gas filler is a device or container used to refill butane lighters, such as refillable lighters or torches. It typically comes in a pressurized canister filled with butane, a type of liquefied petroleum gas (LPG) commonly used in lighters because it is highly flammable, odorless, and clean-burning.

Here’s how it works:

Select the correct nozzle: Many butane cans come with multiple nozzles or adapters to fit different types of lighters. Ensure the right nozzle fits your lighter’s valve.

Refilling process:
First, turn the lighter upside down to locate the refill valve at the bottom.
Insert the nozzle of the butane can into the valve.
Push down to release the gas into the lighter. Hold for a few seconds until the lighter is full.

Let it rest: After refilling, let the lighter sit for a few minutes to allow the gas to settle and any excess air to dissipate.

Butane gas is highly flammable, so refilling should be done in a well-ventilated area away from open flames or heat sources.
