Seal ring size method:
1. Look at the size number written on the seal ring;
2. Measure the inner diameter of the pot;
3. You can see the size of the pot body or the steel stamp on the bottom of the pot
(If the bottom of the pressure cooker and the model of the pot body are invisible, the inner diameter of the pot can be measured to determine the size, provided that it is an aluminum pressure cooker.)
Note: Light shooting and different displays may cause the color of the item in the picture a little different from the real thing. The measurement allowed error is +/- 1-3cm.
