Size verification: If the model number on the pot bottom is unreadable or worn, follow these steps to confirm:
First, verify your pressure cooker is made of aluminum alloy.
Then, use a tape measure to measure the inner diameter of the pot body (i.e., the diameter inside the pot opening).
If the measurement is approximately 28 cm (11 inches), it is compatible.

Maintenance and replacement recommendations:
Cleaning: Hand wash with warm water and mild detergent. Alternatively, place in the top rack of the dishwasher.
Replacement cycle: To maintain optimal sealing performance and ensure safe use, replace the gasket promptly if it shows signs of aging, deformation, or loss of elasticity.
