I need the sizes of the Breech o ring. I have searched and looks like a #011. 

Also I am experiencing valve lock. I have converted from the old style non spin lock tank to the spin lock High flow valve and top hat. Super Sear trigger, 24" 16mm LW .22 Barrel. Installed also the hammer weight.

The gun is accurate shooting 21 Baracuda at 1005 fps with the power wheel on 0. I am working the fill pressure to get away from the valve lock. 

I also have the seal kit and compared the breach seals to my poly seals. The #010 looks to be the same seal in the dur90. What specs I saw posted the size as :7/16 x 5/16 x 1/16 . Any one got the correct size and common #. I can mic the new o rings but was looking for the correct specs for use of the better o ring and local availability. Thanks

I know your looking for the correct size which I could not tell you but I do know talon tunes has upgraded breech o-rings which help. I have them on my wife's talon-p and they will work for your talon. http://talontunes.com/shop/breech-o-rings-90-durometer/

TT also sale some o ring kits and other upgrades for the Air Force line up that will make a big difference in performance and looks if you choose. Sounds like your top hat is out to far if you are getting valve lock. Is it dumping all your air when you get valve lock? Happens after you fire the rifle?

Looking Like 2700 psi is my fill point. On lager fills the guns has to be shot down till Valve lock goes away. Over the chrony on the 3000 psi fill the fps are much lower than they should be but after the VL goes away all is good. I have the 90dur in the gun but was not sure if the o ring was the correct size. I do have some TT ones some where. 

I was wondering if they were a standard Oring or a metric? Thanks and as you mentioned about the top hat, Ill give it a check.
