ᐅ IKEA-Atlant Sink Drain, Seals

Hello,
I bought a second-hand, older but well-preserved IKEA kitchen and am now quite desperately looking for replacement seals for the Atlant sink drain faucet (see attached picture), because I can’t get the sink drain to seal properly with the old seals from the used kitchen.

I haven’t had any luck at the hardware store, as the seals don’t seem to have standard dimensions. And I can’t get them from IKEA because the model is too old.
Could someone help me find a source for original or compatible replacement seals?

Best regards, Dietmar Heil from Friedberg, Wetterau

Hmm.. have you tried searching on eBay Classifieds?

Best regards
