I have an n79rh nailer, and the trigger assembly is blowing air-if i change the "o" rings will that fix the problem?

Welcome to the forums! Yep, you can buy a rebuild kit and the "o" rings should take care of it. Incidentally, be sure to put a few drops of oil in it before each use. That helps keep the o rings lubricated and fills the void to prevent air from escaping. Running it all dry will cause plunger as well as o ring damage.
