Hi are these the same as 349513 09 ?

Don't know to be honest with you, but worked on my flusher system sorry I can't be more helpful.

What are the measurements of these diaphragms, please? Height and width/diameter - and is the rubber quite robust?

I'm sorry, but I can't recall the sizing on these. I will say that no matter where you buy them make sure you have a small stock as none of them are particularly robust and can fail without notice. They seem to last approximately 2-5 years dependant on use.
