FX Panthera Valve Rod Leak

My one-month old .22 700 cm Panthera has developed a serious leak where the valve rod (20924) passes through the valve holder (20925). I've taken the rifle apart and visually inspected the o-ring in the valve holder (15016) and the valve rod. The o-ring looks OK and the valve rod does not appear to be bent. Nonetheless, the leak is severe.

I've looked through the archives but have not found anything specific to this problem. My in initial thought was to buy a new valve rod and o-ring and hope for the best.

If anyone has has additional insight into this issue, I could really use the help.

Thanks

Had same issue with a couple different guns one being panthera which i fixed with a new o ring and one in a fx king which also needed a o ring so to be safe get valve there cheap and couple of o rings should fix you up
Thanks,

I'm going to order parts shortly. Is your advice to replace the complete valve assembly or just the valve rod and o-ring?

By the by, who else but Mercedes Benz would engineer a device where the failure of a small innocuous part that requires substantial disassembly and a special tool to access could render the device completely useless.

Давно известная проблема. Пломба 20925 нуждается в замене. Эта проблема часто возникает из-за дегазации. Вы просто не представляете, во сколько обойдется ремонт этого узла в России.
I've read about the costs of airgun shooting in Russia. Thank you for your comment.

it is the third time this problem has happened to me, the first time due to a shot with the rifle without pressure and the O-ring x1-2 broke, old version of the valve, the second time the same or O-ring broke without particular causes, and the third time I attach the photo, the valve is destroyed

the rifle is one year old, now I'm waiting for the cap, valve stem and seat

That's ugly! I've ordered three x-2's, three B-3's, one x-5, and one x-6. The valve seat was not removed because I did not notice any air leaking from the barrel. It would be just my luck to repair the x-2 and then find that the x-2 leak was covering up a valve seat leak. What did you use for a tool to remove the valve seat?

Thanks

Это некрасиво! Я заказал три Х-2, три В-3, один Х-5 и один Х-6. Седло клапана не было снято, потому что я не заметил утечки воздуха из бочки. Мне просто повезет, если я отремонтирую x-2, а затем обнаружу, что утечка x-2 скрывает утечку в седле клапана. Что вы использовали в качестве инструмента для снятия седла клапана?

Спасибо

I had to buy the specific tool to remove the valve, I'll put it in the photo, you could try using a wall plug of the correct size

Every single car manufacturer out there for at least the last 20 years. Lots of little bits made to barely do the job by the cheapest supplier that will totally screw or confuse a computer, which tends to daisy chain to other systems not related. They can be hidden away where a knowledgeable tech with lots of experience would need a full 10+ hours to get to it and put everything back, with a book value of 15-20 hours. Problem is, most stealerships run on a seniority system with the techs, the senior techs take the good jobs(book value high, they can do it in way less time and knock 5-6 jobs out a day instead of 2-3). A friend of mine is a tech at hendrick's honda dealerships, he has been there long enough(30 years) so he generally books a minimum 80 hours a week and often much higher, and works about 35, I think his all time high was booking over 120 hours in a week, actually working less than 40. So you typically have the junior techs working on the problem childs until a manager may intervene. All for a 10 dollar part or worse yet, just a wiring connector that renders some system wonky but not dead because it gives computers random data that propagates and affects other unrelated systems. Very common with all manufacturer's. I know two people, one on a ford f350 just short of 3 years old and one with an audi 2 years old that the manufacturer's bought their vehicle back rather than fix it after months of being in the shop. They knew what was wrong with the ford, built on friday afternoon, a ton of substandard connections that finally deteriorated to the point you fix one another fails when something up or side stream is "fixed". Every single inch of wire would have to be pulled on the truck and replaced. The truck was crushed when they bought it back, too much money to do that on an assembled vehicle and replace the entire vehicle wiring, it would require entire truck being taken apart. The audi is out in the wild with nothing but a manufacture buy back on the vehicle title, anyone buys that one is screwed, after the first 9 or so months from new, it never didn't have a problem, many of them and getting worse every month. At least the ford guy didn't have to hire a lawyer, the audi guy had to get a lawyer.

Well, my question was rhetorical, but I see your point and wholeheartedly agree.
