I have a Hatsan Flashpup that tops off at 200 bar. What pressure do you all store your pcp rifles at?

i try to keep mine at the optimum pressure they shoot the best at .. thats usually not topped off, maybe 2800 for a 3000 gun ...

I've had my flashpup over a year and a half. 200bar or close to it. No leaks...I just fire it at least twice a month

I bought my flashpup about 3 weeks ago and I keep having leaks in the fill port valve seat. I changed the O ring with the one that came in the parts box and topped it off and left it at 200 bar for three days and it didn't leak a bit then today I shot a couple of mags and when I topped it off it started spewing air from the fill port again. I pulled the valve and the O ring looks perfect and clean. Valve seat looks perfect as well. I'm thinking the check valve spring may be to weak to keep the check valve closed. Have you had any issues with your check valve in the fill port?

I haven't had issues with the check valve. I have only used a compressor to direct fill, I don't know if using a tank would be different? Might be worth trying a new spring. Seems strange that it happened after firing.

Also make sure it's the correct size oring. Brothers in air on YouTube has a whole video and list of the proper orings.

From what I've researched today my problem may be that the gun has to be cocked for it to hold air. I'm gonna see in the morning. If this is the case then hatsan should put it in the user manual.

It should "hold" air.. cocked or not .the fill valve is leaking? It's on the opposite end of the hammer...

Then you used the wrong oring size...it doesn't come with the gun..look at the picture I posted..that's the correct size

So what do the O rings fit that came with my gun? There are two large O rings that look like they may be for the tank then there are three small O rings that are all the same size and match the intake valve when compared.

The fill probe, fill probe plug and the intake valve use the same O ring from what I've micro metered so the fill probe O rings should work on the intake valve from what I can tell.

According to the brothers in air video they are different. But if you think it will work use silicone oil and replace it
