I have a Hatsan AT44, and air cylinder is leaking, I changed oring on white valve seat and still have leak. I believe it is white valve seat as there are scratches from taking out. I am having trouble finding one, any ideas where I might find one or a used valve ?

Regards,

Greg.

I have a bit of experience with the AT44. I have often found that when I mess with the internal valve seat, white one with oring, it takes a bit of pressure to make it seal properly.
So, if you have a bottle giving it a quick burst may get it to seal. Followed bay some quick firing to get the valve pin aligned and seated. I can get mine sealing using a hand pump, and pumping as fast as I can, it works.
