Go to fx airguns, click support, click drawings (diagrams), click Typhoon for diagram & parts. They're uncommon nowadays so don't know what "commonly" happens to them but drawings & parts list should help. They're OLD so seals somewhere are probably shot.

You might try reaching out to sniperlaybo which if I remember right is Ernest Rowe's username. He is THE expert on FX rifles and may be able to help.

Just for information.

I did get the rifle in question in hand and found that it leaks at a high rate, so much that after filling it to 200 bar, each consecutive shot lost about 30 fps and within 5 shots it went from 916 fps to less than 750 fps. After waiting a few minutes the next shot was less than 400 fps. There is no gauge on the rifle to see what the pressure is.

I did open the rifle and is was not a problem with any O-ring. I found that the valve itself was leaking, not any O-ring on the valve unit. I cannot see damage on the teflon ? valve seal (or whatever material it is) or the valve seat. It is difficult to see detail on the valve seat as it is, what looks like stainless steel, bushing pressed inside the bronze valve body. I don't know if it is leaking around the bushing / valve seat or at the seal itself.

I will contact our local FX dealer, Patriot and if they cannot help, I will contact FX Sweden. Since it is an old PCP I doubt if they will have spares.

FWIW
I would not be surprised if FX Sweden has parts for the Typhoon
And their new USA service centers (UTAH & Cape Fear) can get them.
You can also find parts at Bagnall & Kirkwood in the UK
Hope this helps

Thanks.

I am in SA and today I did source and ordered a new valve pin from Patriot, the SA agents for FX. I think it is the teflon seal in the valve pin that is worn but still smooth, the rifle is about the age of a dinosaur. The brass valve body has a stainless steel valve seat and I doubt that will be the problem but if I find that it must be replaced as well, they will have to order it from Sweden. The valve pin cost R183, that is the equivalent of about $10 US, I thought it will be more.

That's very good news.
And much less expensive than B&K
I'd be curious to know what the turnaround time is on receiving it from Patriot/FXSweden

*Breech o-ring >>> Check
*Transfer Tube o-rings >>> *Check with Tissue test for both.
Oil or grease On or Within hammer bore >>> Check

Sweet!
Good to hear the problem is solved and the T-12 shoots nicely.
Most likely one of the reasons FX earned the reputation for producing accurate guns early on.
With no need to modify the tune because they did their homework in that regard too.
And I am not an FX junkie

Also
Pleasantly surprised how quickly the parts got to you from Sweden
Where in S.A. are you @Caliber 22?
