This question is regarding Bristan Pisa Thermostatic Surface Mounted With Adjustable Riser - Shower Spares

Bristan Pisa surface mounted back seal

On the back of the unit there is a large brass nut with a rubber seal at one end of the thread and a white plastic seal at the other end which I presume seals against the new cartridge. It is cracked in half.Can you get a replacements, I cannot find any.

Thanks.

The body in your picture is like the above which has a screw in rear section.
 Whereas the Pisa has an back plate with a brass insert.
