Hi!
Decided that today I'm going to enjoy myself and shoot as many tins as possible. Shot maybe 50 pellets or so and went to fill it up again. Did so and then came the hissing sound. It stopped so I shot some more in but came back when I filled it up the next time. The hissing sound and leakage is in the front of the airtube, where the fillprobe goes in. Suggestions?

That's unfortunate but a pretty easy fix if you have spare o-rings. Sounds like E-12 or E-13 oring. Doubt its both or all 3 . I have a .25 wildcat also and only replaced orings on my barrel and fill probe so I'm not sure of the exact size. I know some airgun sites charge a lot for orings, not sure why, but I matched mine up at home depot in the plumbing section and there selection of different sizes was huge.plus no wait and very cheap.

I had a leak that would come and go with my fill probe when filling. Not sure why. I replaced the orings and its been fine ever since. Maybe it only leaks when filling under higher pressure? It is covered under warranty but then you have to ship it and wait. Also when I received my wildcat and removed the barrel I noticed the two orings on the outside at the breech end had some significant dry rot and cracking. Even though its a new rifle the orings weren't.

Hi Airslinger. I've never seen it done that way. It works though. Johan from Fx Airguns had a post here walking through bleeding the air by loosening the brass allen bolt on the left side of the breech block. I bled my airtube that way before I had it camo dipped , but your way also works. Its good to have options. Thanks.

"FastEddie"If your going to repare those orings you need to bleed the air out first via the brass allen bolt on left side of breech block.

This is the right way to bleed the air from Wildcat. The method shown in the video is not correct.

Hmmm looks correct to me. The man in the video was able to safely degas the wildcat.

Granted it is not the way that Johan put out, it is still a safe a proper alternative. Ernest knows his stuff.

I've been expecting more leaks on my Wildcat and so far it's has been at the regulator where air was leaking out the Vent hole. I was loosing 10 Bars after an 8 hour period. 

As for Issue, check where the pressure gauge screws in. Use soap and water to confirm. If it is coming from where the pressure gauge screws in, try tightening the pressure gauge a little. If that doesn't help, you'll need to replace the plastic washer inside. Not sure what size it is. I'm sure a replacement can be fount locally.

Here's a link to the pdf shared by Johan. Note that this pdf looks to be for the Wildcat 25 when it it comes to the o-ring size. Locations to check relates to both the 22 & 25 version. Also, I have only taken the Wildcat apart using the second link below to access the regulator to changed outer the o-rings. The o-rings I used to replace the 'outer regulator' orings were the o-rings used for the Benjamin Marauder 25 (Part# 1763-26). It seems to be holding air so far...and that was over a week ago. To check if there is a leak through the vent is to put clear tape over the hole and see if air is escaping.

Link to another post to get to the Wildcat regulator to replace the o-rings.
