Hello everyone!

I am desperately looking for a so-called “air admittance valve” (according to Google). Could it have a different name?

It has external and internal threads of 1 inch. Chrome plated.
These air admittance valves consist of two parts, which are connected by fine threads.

I already have one valve but need an identical second one!

I have uploaded a photo of the two parts of my air admittance valve for reference.

The problem is that I need one with a 1-inch size, also known as DN25.

Despite extensive searching, I have not been able to find the English term. None of the local plumbing suppliers or stores have this part or can order it.
There are also no manufacturer markings on the valve itself.

Maybe someone here can help me? I would be very grateful!
Best regards,
Klaus
