That one appears to be an old model and is out of stock everywhere. And from the reviews, it does not seem to actually seal the lid of the pot. No better than the cutting board I currently place on top of the pot to "seal" the lid.
- "Lid is too big, not even close to sealing."
- "very loose fit"
- "This cover just rests on top of the Instant Pot liner. I was expecting it to "snap" on, similar to Tupperware, or something. I'm very disappointed."
this is the exact product you're asking for ("Creates an air-tight and water-tight seal on the Instant Pot stainless steel inner pot.")
