This is a hard to find part but PA had it in stock thankfully. This is for a Hatsan MOD 125, .25 cal. The original spring was not comfortable at all to shot and accuracy was lacking. They (Hatsan) offered to change it over to a Vortex (125.00 + shipping) I took them up on it. The piston gave out but 'Ive always wanted to break a rifle down so I ordered this and the silicone lube and fabricated a spring compressor. Once I reviewed the YouTube video on how to do it It only took and hour to take apart, clean thoroughly and replace the seal. What I found is Hatsan did not clean the spring chamber very well and used the standard grease. This caused of course poor performance. Once everything was cleaned properly with the new seal lubed as they talk about here with just a few drop and then making sure the chamber is lubed and things move well I went to test it and WOW. Smooth is a great feeling and the accuracy went up 1/4 inch at 30 yards consistently

I hope that there will be other seals and springs/gas pistons available now that I have done this it would be nice to clean up the rest of my rifles.

Take your time, take pictures of each step in disassembly to help if you get lost or distracted.

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.

It would be nice if Hatsan had better quality control so bad seals were not installed on the pistons.

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!
