Quick answer
Instant Pot sealing rings are sized by pot capacity, not by model. Instant Pot sells three sizes: a 3-quart ring, one ring shared by all 4, 5 and 6-quart pots, and an 8-quart ring. A Duo, Duo Plus or other model of the same capacity takes the same ring. The capacity is printed on the inner pot and on the box.

| Your Instant Pot | Ring to buy | Notes from Instant Pot |
|---|---|---|
| 3 quart (3 L) | 3-quart sealing ring | "Designed for all Instant Pot 3-quart electric pressure cookers" |
| 4, 5 or 6 quart (5.7 L) | 4, 5 & 6-quart sealing ring | One ring for all three sizes. |
| 8 quart (8 L) | 8-quart sealing ring | Made for 8-quart pots only |
| Duo Crisp with Ultimate Lid | No separate ring | The ring is permanently attached to the lid. If it's damaged, Instant Pot says to replace the lid. |
Instant Pot also sells two-packs in clear and colored silicone. Some models come with an extra ring. Instant Pot's FAQ suggests using one for sweeter dishes and the other for savory ones, and the manual notes that silicone is porous and holds onto smells.
