Yeah that's the general standard. However, I'm here to say even if it's "standard" if you go with a custom that's in any way expensive, well I'd email the tank and specifically ask if it would work, etc. Sometimes it just doesn't fit well for whatever reason either too loose or too tight . That can sometimes be remediated by removing or adding an Oring.
I like Kidney puncher for driptips, they're usually inexpensive, but I don't ever look for the larger size, usually. Etc..
