I'd think a Hatsan Mod 95 seal is the same.
Pull the old seal and measure it. Harbor Freight probably has them if no where else.

Just eyeballing them and they appear the same.

You can take the old seal out, and add some dental floss behind it to kind of cheet.

Not much of a seal there....
Is it just an O-ring?

The Mod seal from Hatsan will work.

Or you stack o-rings and add floss if needed.

It should be about 4 mm thick front to back. Kind of a flat o-ring thing.

In my old Win. 1000, same gun as a 800 just less spring, I have a breach seal for B2 from a B2 parts/repair/cleaning kit. Actually I think there's 2 in there to make it high enough to seal.

The Hatsam Edge seal was correct ID/OD, but too thin........
I put a 1/16" O-ring in behind it, and that was a bit too much...the new seal pinched when closing the breech.
Maybe a 1mm CS O-ring will do the trick, but I would rather have the correct seal.
According to JG Airguns there were 3 different Hatsan seals, but Hatsan did not change the P/N
the one they have is 14mm OD; mine is 13mm.......
I believe this is the seal it takes:

The original has that raised ring....

Only problem is....the DESCRIPTION box gives one set of dimensions; the DETAILS box gives different numbers........
I have requested clarification from them.........
Nothing is ever easy......

I emailed the Custom Seals guy about the dimensional discrepancies...

He said he did not understand.
I said neither did I...........

If memory serves Air rifle Headquartes has info on the 1000 which is probably the same one.

I've used dental floss behind the breech seal at times. That works pretty good.

It would require about .020" of floss.
I cut a washer out of .020" Delrin.
that seems to have done it.
It passes the tissue test........

I'd probably print a spacer out now days.
