Gamo Piston seal

[KWK]

Actually, that is how i got the response. But thanks! And i see nothing wrong with the seal adapter from them. Although, don't need it, just mentioned it. Vortek are closed until Feb, 1.
What is the 35??

HW35

I kind of figured it out later. Is one HW that uses the 30 mm piston.
Should have retracted my stupid question...

The seal from Czech Republic made it here. (Canada) Ordered Jan 17, so is not bad.
Price is 6 Euro+5 Euro shipping. The cheapest i found. Was surprised to see the box
size it came in. A simple seal would fit in a envelope. I realize they sent me more than
what i paid for. Included was a tool to push the gas ram , and also a cone to help install
the new seal on the piston. It works great, after warming up the seal in hot water.

Finished the piston for my Gamo. Machined diameter closer to size, as opposed
to factory piston that has a lot of clearance. Is that necessary? I don't know. I made
it a lot lighter than factory piston. And since i was at it, figured will try a Weihrauch
seal. I just don't like the wedge on Gamo pistons. Of course, Weihrauch has no 29 mm
seal! So had to figure out sizes to fit, as well to machine a seal down to size. All done.
Results: As expected, shoots slower than OEM. 725 fps from 740 fps. Sounds different,
wish i had a measuring device. But sure has less recoil.
