Filled My Lighter

[Bruck]

Don't ask me, I've never 'purged' a lighter in my life. As far as I'm concerned, it's a practice for people who don't understand gas laws.

I think it's to get rid of the inert impurities that got in there the last time you filled it. Anyway, I get better results when I purge before reloading.

It also cools the lighter in the same effect as putting it in refrigerators, allowing you to fill more butane. It's called Joules-Thompson effect that also happens to can of butane when you are filling up the lighter.
