There is another video above that perfectly demonstrates my steps on a method to refill a Bic lighter.
Place a refill valve at the bottom of the lighter using this process. This encourages you to reload the Bic lighter several times.
When you reload, there are no irritating push pins, no pressing your thumb over the hole, and no liquid fuel spurting anywhere.
To do this, you’ll need a small gas refill valve. Replacement valves for airsoft weapons (Amazon Link) or this one work well. It’s also possible to use the refill valve from a defective refillable lighter in your Bic lighter.
Step 1:
Locate the small hole at the bottom of your Bic lighter. Push on it with a pin or drill bit before the ball lands within the lighter.
Step 2:
The next step is to drill into the hole you just created. You ought to make it wider so that your refill valve will fit inside. The drill bit should not be larger than the valve you want to use. Ideally, the valve should be slightly wider than the drill bit.
Step 3:
After you’ve drilled your hole, flip the lighter over. Shake it up to get the ball and any drilling debris out of the lighter.
Step 4:
Inside the fuel chamber of Bic, the lighters are rubber dividers. If this divider is already in operation, you won’t be able to insert your refill valve into the lighter. As a result, you’ll need to insert something (such as a drill bit) into the lighter and hack away at the divider. When you’re done, shake the debris out.
Step 5:
Insert the refill valve into the hole. You can need to use a razor to scrape the hole’s edge a little. To make an airtight seal, some people apply a dab of silicone around the valve strings.
Step 6:
Now, all you have to do is fill it up with the fuel.
If you put the lighter and butane in the feezer and get it nice and cold before u fill it the liquid will be way less volatile and not spew out of the lighter after you fill it
Good tip, thanks.
