George, it is well known that the nipple works, However, you're gonna have a hard time telling me that putting safety wire on the nipple doesn't help contain any leak that might occur.

You asked the opinions, last thing you need to do is come on here and tell someone he's wrong, I mean, something so simple as an airline on the nipple, and apparently you F'ed it up.

You're not the first or last, but I have seen many a tidy installation that someone took the time to safety wire their air lines. It is common enough practice.
