Help finding piston gaskets for a commercial vintage espresso machine

Hello all,
I own a lever machine dated back from around 1960.
I want to purchase a set of V gaskets for the piston and having some difficulty finding them.
The local company that used to build these machines have no idea where to get the parts anymore.

Sizes are:
Inner diameter is 38mm
Height is 8mm.

I'm attaching some pictures and would appreciate any help! :)

Hi,
the spring part and top look a lot like my brugnetti, which happens to be 38mm as well.

It look like it's a pretty standard fit, faema W and V gaskets.

I think those gaskets should fit.

You can probably get away with a normal o ring. I've used normal viton orings in my caravel.

Are these two the same? Or do I need a different one for the middle shaft?

I can't tell if the originals were normal o rings since they're so worn out... but v should do a better job don't they?

Two different ones W (or X) for bottom and V for top (not sure about up or down now but could check)
I don't think you need 3 gaskets, I have two and a space in between as well. Don't think an O-Ring would work; you need the water filling the gasket to make a proper seal.

Theoretically, orings aren't suitable for the low piston speeds of espresso machines, as you can get spiral failure.
In practice, I haven't noticed that in two years on my Caravel. I wouldn't hesitate to try some o rings if I would find it difficult to source new seals.

Thanks Fred, I think I took the middle one a part when working on it a few years ago. But now I question my memory...

Bluecold, I'll start with the v and if I'll have nothing to lose will go for the o's :)

Thanks, hope I'll manage to solve this, been lazy long enough with this project!

Have you removed them? Can you show photos? Even if they're worn, you can probably see what they were.

Also I wonder if you have any badge or identifying markings on your machine, or measurements of the cylinder and the piston?

The gaskets seems perfectly stright.

There's nothing written on the cylinder itself, I think the company that built the machines bought the group heads from some other company abroad, but all I have is rumors...
