Instant Pot Duo Multi-Cooker
Food-grade 304 stainless inner pot with a stainless lid underside and steel anti-block shield - the only food/steam-contact non-metal is the silicone sealing ring, landing it at silicone-only.
The verdict: Silicone only
The inner cooking pot is uncoated food-grade 304 stainless, and the underside of the lid that faces the food and catches condensation is stainless too, with a 304 steel anti-block shield over the steam pipe. The one non-metal part in the sealed food/steam path is the silicone sealing ring (plus a small silicone float-valve cap). The plastic on the unit - outer lid housing, control panel, steam-release handle - sits outside the sealed cooking chamber. So contact-wise this is silicone, not plastic.

|---|---|---|
| inner cooking pot food-grade 304 (18/8), no chemical coating | Stainless Steel 304 / 18-8 | Yes primary 🔥 |

| anti-block shield 304 steel shield over the steam release pipe | Stainless Steel 304 / 18-8 | Yes incidental 🔥 |
| sealing ring silicone gasket seating the lid; the main non-metal contact part, replaceable | Silicone | Yes seal 🔥 |
| float valve cap small silicone cap on the pressure float valve - not a food surface | Silicone | Yes incidental 🔥 |
| steam release valve / handle food-grade PP + steel; sits above the sealed chamber | Polypropylene PP, #5 | No |
| outer lid housing / control panel / handles | Plastic other / unspecified | No |
The mainstream electric multi-cooker: one countertop unit that pressure-cooks, slow-cooks, sautes, steams, makes yogurt, and cooks rice, run from a digital control panel with presets. The 304 stainless inner pot lifts out to serve or wash, and the whole thing is a familiar, well-supported appliance with cheap, easy-to-find replacement parts. The silicone sealing ring is a wear part that absorbs food odors over time and should be swapped periodically.
Pros
- Uncoated 304 stainless inner pot and stainless lid underside
- Steel anti-block shield; food/steam path is metal except the seal
- Silicone sealing ring is replaceable (and swappable for a fresh one)
- Doubles as pressure cooker, sauté pan, yogurt maker, steamer
- Slow-cook mode uses the same 304 stainless inner pot - a metal-crock slow cooker with no glaze
Cons
- Silicone sealing ring is required and absorbs food odors
- Plastic outer lid, control panel, and steam handle (out of food path)
- Not fully plastic-free; strict silicone-avoiders should use a stovetop pot
- Electronic unit is not as repairable/long-lived as a bare pot
Common questions
Does the Instant Pot Duo Multi-Cooker have plastic in it?
No petroleum plastic touches your food. On the Instant Pot Duo Multi-Cooker, the sealing ring and float valve cap are silicone, and the rest of the food path is stainless steel. There is plastic in the steam release valve / handle and outer lid housing / control panel / handles, which never touch your food.
What is the Instant Pot Duo Multi-Cooker made of?
Part by part, the Instant Pot Duo Multi-Cooker is: inner cooking pot — stainless steel; lid underside (food-facing) — stainless steel; anti-block shield — stainless steel; sealing ring — silicone; float valve cap — silicone; steam release valve / handle — polypropylene; outer lid housing / control panel / handles — plastic.
Does the Instant Pot Duo Multi-Cooker contain lead?
Lead was detected somewhere in the Instant Pot Duo Multi-Cooker, but not in the surface that touches your food. That finding comes from independent lab (XRF) testing, not a manufacturer claim.
Does the Instant Pot Duo Multi-Cooker have silicone in it?
Yes — the sealing ring and float valve cap are silicone on the Instant Pot Duo Multi-Cooker. They are seals rather than surfaces your food sits against, which is stainless steel.
Is the Instant Pot Duo Multi-Cooker BPA-free?
No plastic touches your food on the Instant Pot Duo Multi-Cooker — the food path is stainless steel and silicone — so BPA, which comes from polycarbonate and epoxy plastics, is not in play here.
