Where can I get a replacement gasket cheaply? Do the 22cm seals from other manufacturers also fit on Galaxus?
Should be standardised, right? The Tefal sealing ring measures 23cm on the outside, but it may have worn out or the inside may have been messed up.

I can't answer that

I use it to cook rice, legumes etc., it is quite good

I bought the pot and can recommend it without hesitation. Very good quality, everything feels secure. The pot makes a lot of pressure.

80 kPa (12 psi)
