I blew an oring on my FX Dreamline cf buddy bottle, it's a Best Fittings bottle and valve. Does anyone have any idea of the oring size? It's the inner ring that you can see in the valve thread entrance where it fits to the rifle.
FX FX Best Fittings CF air bottle valve oring size
- Thread starter bchannell
- Start date
The o ring in the front of the valve is a 9.3 x 2.4 NBR 90 durometer

I bought the standard FX seals, as listed above, but they are huge and won't go in the Best fittings valve. I'll try again today, but I'm guessing it's different.

I was wrong, that is the same size on the BF valve. Someone had two orings in mine and the "extra" oring is what blew out. I pulled the other out and put in a new one, no problem.

Well I took the bottle off the gun and heard a loud pop. When I got it off there were bits of oring everywhere so I assumed it blew an oring. Then I realized the original was there and just hard to see. It was worn out and not sealing. Took it out and the new one went right in without much trouble.

I let the o-ring sit in hot water for a few minutes so it becomes soft. Then use a o-ring pick tool to seat it in the valve. I use this one: https://www.amazon.com/gp/product/B07Y8QWX9B/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&psc=1
It will take a few tries to get it to work but any type of tool pick or needle nose pliers/surgical instrument can work in this use case.
Good luck

No, I have not tried changing it. I believe there is a tool that helps in removal but I cannot recall. I am sure if you go to youtube and search FX air bottle valve assembly. You will find videos on how to fully disassemble.
