The sealing ring of pressure cooker is not necessarily universal. If the same brand has something in common, if it is not the same brand, don't be generic, so as not to cause unnecessary harm. The pressure cooker problem is no joke. Personal advice is to go to the physical store where the pressure cooker is purchased for consultation. Most of them have accessories. If not, they will also have a purchase channel, so it will be much safer to use the original sealing ring.
Remind never to buy ordinary accessories yourself. When the pressure cooker works, the inside is vacuum. When there is a problem with the sealing ring, the sealing effect will be bad. If there is a problem with the pot, it is a food problem, and the pot body, gas stove or people will be injured.
