O rings vs loctite on cocker barbs?

[SR_matt]

I feel like I have seen this talked about before but am coming up dry with searches on google.

Does anyone use o rings on barbs for the pneumatics or is the general consensus just to loctite them to seal them up?

If using o rings what are the right sizes/duro/material for it?

On paper o rings seem like they are a simpler and more easily serviceable choice but at the same time it may be looking for a solution to a problem that doesn’t exist.

I just use loctite. Never had a barb leak unlike with the orings

loctite is the way to go.

use a blue Loctite or Loctite 545 which is a thread sealant so you can get it off again without trouble.
