That's just over 25 euros, you can make your own piston for much less

i made piston valve, but i get some issues with it
leaking (that i can fix) the major problem is the piston seal
because i use such i high pressure 700psi the seal always cut off and that happen even with 2mm seat smooth surface
i looked for hard rubber that i can machine it with the shape of piston but couldn't find .

Can't you enlarge the seat externally by epoxying some extra tubing, like I did here?

But, I have yet to test it. When I get around to testing it I will let you how it goes.
