I put o-rings in my Dewalt nail gun trigger ad nauseam. Hope this is helpful.

I have to be honest folks, I used a bit of atf as an assembly lube and my trigger quit working. BE ABSOLUTELY SURE TO USE A CORRECT AIR TOOL OIL.

at about 6:04 you point out one of the rings is most important. but you do not indicate which position it is. there are 3 on that piece

You should get head cam to show how you remove—be even more helpful.

Would you have a video how to remove the trigger?

Thanks for your video. Where the air was leak? From the front where the nails go out or by the trigger? I have replaced the orings inside but all air exit by the front where the nails go out and no leak by the trigger.
