Giant MPH Cylinder part name

[Dubious]

Hi,

I've managed to break a part one both of the hydraulic reservoirs on my wifes bike. The metal (brass maybe) washer that seems to hold the fluid in the reservoir.

Can anyone let me know what the part I need to buy is to fix this please?

Much appreciated!
