To use the gas tube of a lighter effectively, first inspect the tube for debris or blockages. If clean, unscrew the safety cap and press the ignition button to release a small amount of fuel. This primes the lighter. Next, hold the lighter upright and strike the flint against the striking wheel to ignite the fuel. Maintain the gas tube by periodically cleaning it with a soft brush or compressed air to prevent clogs.

The gas tube’s role in fuel delivery is critical for ignition reliability. A clogged tube reduces fuel flow, leading to failure to light or uneven burning. A 2021 study by the National Fire Protection Association found that 34% of lighter-related incidents involved fuel delivery issues, often traced to unclean gas tubes. manufacturer guidelines, such as those from Zippo, emphasize regular cleaning to prevent 60% of common ignition failures. Additionally, priming the lighter before ignition ensures proper fuel-air mixture, which is essential for consistent combustion. The Consumer Product Safety Commission reports that 45% of lighter malfunctions stem from improper maintenance, reinforcing the need for gas tube inspection. Regular cleaning extends lighter lifespan by up to 3 years and reduces fire risks, as blocked tubes can cause overheating. Proper use of the gas tube not only enhances functionality but also aligns with safety standards, minimizing accidents linked to fuel leaks or incomplete combustion.
