Installing 3-way with an o-ring - is this tip legit?

[StoicPotato]

I've been getting my butt kicked by an autococker that just won't cycle consistently, and stumbled upon this video. Specifically, at the 2:07 - 2:25 mark, he mentions installing the 3-way with an o-ring to help eliminate some of the play.

I think this may help with the issue I'm having (I've noticed the 3-way is really sensitive as installed and will start venting in a light breeze, but maybe that's normal? I'm pretty new to this), but I haven't heard of this before. Is this legit, and specifically would there be any issue doing this with a Bomb II?

That play can help account for the imperfect alignment and action of the trigger and timing rod. I have put an oring there before to reduce it and for appearance, but in theory it’s moving to stay in line with the rod

I put an oring on all of my 3 ways that i install.

Thanks for the responses - I'll give it a shot.
