Hatsan Jet II question

Can someone please tell me for certain what the thread size on the fill foster fitting for the Jet II is please? Mine is leaking like a seive. I have taken it apart and cleaned as well as applied silicone to no avail. It has to be the cheapest valve I have ever seen. I ordered 2 new fosters on Amazon specifying 1/8 bspp thread, which is what I had read is the correct thread for this foster. "If" the original is bspp thread then the Chinese fosters I received are not. They will not work unless I just allow them to cut new threads in the air tank. Thanks for your help.

I had a jet 2 for my first pcp. For some reason It came with a quick disconnect female foster coupler that had 1/8 bspp male threads on it. I still have it. I also had a blitz, and that brass fill probe needed a female threaded adaptor 1/8 bspp to 8mm quick disconnect They are made in turkey and definitely have bspp thread

Good to know in the event I decide to change it out; having a dedicated female coupler is as convenient as a specific fill probe.
