Things I liked: Perfect fit for my brand new Hatsan 125TH. Bought this to replace a defective factory seal, and the performance now exceeds factory specs. I bought my brother the same gun, and it's velocity is deteriorating just like mine. I'll be getting another one of these and replacing the factory seal on his gun as well.
Things I would have changed: It would be nice if Hatsan had better quality control so bad seals were not installed on the pistons.
What others should know: This seal change requires tearing down the entire gun. This is NOT your simple DIY project, and requires extensive knowledge and tools most people do not have. Know what you are getting into before attempting this project!
Things I liked: Fit perfect and seems tough Tuned my gun to a much more accurate shooter. It say's to be installed by a professional. Well I guess the factory should try that and it wouldn't need replacing.
Things I would have changed: Nothing worked fine
What others should know: Check your gun, this will improve accuracy a lot.
Things I liked: Good quality material
Things I would have changed: nothing
What others should know: Perfect for Hatsan 125 series. The factory seal blew at about 200 shots on mine and when I pulled the piston it seemed to be undersized a tad. This one fits tighter. I soaked it in warm water for a few minutes and it popped right on, no tools used
will this fit the Hatsan 155?
I don't know the specs on the 155 but I can all but guarantee this is not it. Yours probably takes the same seal as an 85 or similar size models. The 125 is a magnum so it's bigger.
how do i change my piston seal on Hatsan 125th??
The actual removal and install of the seals is easy, but you have to take the gun apart to get to it. Youtube has lots of vids of people taking break barrel guns apart to give you an idea. I think it's pretty easy and don't use any special tools but for a first timer it looks intimidating. Also be careful not to tear up the new seal on the sharp edges in the gun, which the oem seal will usually bear witness. So either smooth said edges or be super careful installing.
Does this work in umarex octane? Thanks in advance.
No, use a seal for a Diana 350 which are pretty easy to find.
