Copy and paste “grohe 41131275” into your search engine.

I did and came up with dozens of cartridges that look to match the one in your picture. One example is Here. The exact part numbers may not match, however often the manufacturer will change a part number to reflect the year and month of manufacture.

You will have to do your own comparison shopping. Or take the cartridge to a plumbing supply store and they will match it up.

Grohe shower valve cartridge replace
I was just searching for parts for my kitchen faucet and came upon a thread in here about it and many said that the Grohe faucets have a lifetime warranty, wonder if this goes for the cartridge as well? I am going to call them and see as my handle on my faucet has deteriorating rubber on it, it’s all sticky. Jeff LoGiudice Temple Terrace, Fl 1984 Bluebird Wanderlodge PT40 1998 Newell 2000 #490 1986 MCI/TMC 102A3 (sold) ... I contacted Grohe for a replacement part (they had sent me the kitchen faucet head N/C in the past).
