They're usually around an inch long but may be shortened for several reasons.
They only need to be long enough to reliably hold onto the little O-ring.
I've cut all mine down to ~1/2"...
Cheers!

Thanks for the input. I thought they could be shortened, just wanted to verify

Just out of curiosity, why would you need to shorten a 1" long gas in tube?

More than likely it's to add more liquid for a CO2 purge. Less head space that way.
They're not all 1". Within my set of 16 kegs I've found some that were much longer, verging on 2" long.
That can be a problem when you're doing closed CO2-push transfers and can't see how full the keg is any more.
After a couple of slight over-fills that reached the gas dip tubes I said "eff it" and when a keg kicked I cut its gas tube. All 16 have been cut.
I've since gone to using a scale when filling kegs. Much more precise.
If I had done that from the jump there's a chance I'd have never cut the tubes, but there's zero harm in cutting them, and it does increase the margins...

I use my cope pipe cutter, easy peasy to cut. I collapse the cut slide to make it easy to turn with a screwdriver in the cutter.
