Leaking from the thermostatic cartridge housing

I have dismantled my 3 way Crosswater Wisp diverter valve and this is the cartridge that is fitted. The cartridge still appears to work fine and I suspect that the reason it leaks a little is that the sealiing rings, in particular the middle diagonal one appears to have stretched and is a very loose fit around the cartridge. Is there a replacement sealing ring kit available for this please ?

Unfortunately there is no seal kit for this valve, it is unlikely to be that seal but not impossible!
