Might this be the one
Even same color as the original. :) Thanks. Will get one for sure, but would like a softer one.
Whish Weihrauch made a 29mm seal. Would adapt the piston to fit.
 
The product name is actually a bit misleading :)

By 33mm they mean compression tube outside diameter.

In product description it states clearly

33MM IS THE OUTSIDE DIAMETER OF THE CYLINDER THE INTERNAL DIAMETER IS 29MM

THIS CAN BE EASLY CHECKED BY MEASURING THE OUTSIDE OF THE CYLINDER TO ENSURE ITS 33MM

SUITS ALL GAMOS LISTED A HAVING A 33MM CYLINDER AND A FIXED WEDGE 14MM X 9MM PISTON FITMENT

Apologies! Just checked and yes, the tube's O.D. is 33mm. Why would they mention that size. But, my bad for not reading the specifications. Also, found a site from Cech Republic, CZ brand, colorless. emailed there also, if would ship overseas.

Have ordered a CZ made. Hope it is softer and more flexible than the factory
that was on, and happens to be blue. Tried removing it with heat gun, with no
success. The seal is solid and the angle on the piston's retaining pin is way to big.
No need for such an angle. Was tempted to believe is held by a flat head screw,
but no hex for wrench. Had to cut the seal just to see what is going on.

Well, fixed wedge piston seals take a little courage to remove and put on. In both cases, no matter how hard the seal is, it is always recommended to keep it in hot water for a few minutes to make them softer. There is actually no need to worry that the seal will break, since the plastic it's made of is very sturdy. I usually take them off with a flat-head screwdriver and force. If done carefully, no harm is done to the seal. And for putting them on, I just heat the water to the boil, pour it into a cup and place the seal for 2-5 min., like making a tea :). In that time, the seal becomes quite malleable, although some force is needed to get it over the wedge.

What concerns me about the CZ seal, which is made of PU (polyurethane), is that it's soft and malleable as it is. So no need for heat treatment. These are very good seals, but they can't handle colder temperatures. If it's -5 degrees C (23F), it might become hard and brittle. Just saying out of personal experience :)

Am sure will be able to place a new seal on, but removing the factory one was a nightmare. Courage I had, :), was not worried about the seal, but no luck. So will try the CZ one. If is -5C outside, i will not be using the gun. Will find better things to do then :) Meanwhile, will see if can adapt a Weihrauch seal to fit this gun. Like those seals better.
 
There is an easier way to adapt the Weihrauch seal to Gamo piston.
Cut the wedge on the OEM piston, tap and screw on this adaptor. Will
lose some pressure, as piston will be a little longer. Lot less work. Still
need to cut down to 29 mm.

Does Vortek have a seal adapter for the 35? That's the seal I'd use.

To contact Custom air seals go on eBay and email them there. You will get a faster response
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??
