The Instant Pot’s silicone sealing ring is advertised as a simple, self-explanatory part. But is it really? I’ve been cooking with electric pressure cookers for fifteen years and have owned eleven of them, and I can tell you that this little loop of rubber is the difference between a perfect batch of plain rice and rice that tastes like last Tuesday’s curry.
I’ve lived through the exact scenario where the ring redeposits old flavors into new food, and I’m here to tell you when to swap it out, why it matters, and which replacements are actually worth your money.
Here is the short version before I get into the nitty-gritty:

I don't have a laboratory. I have a real kitchen, a broken dishwasher I've been hand-washing in for six months, and a 65-pound lab mix named Benny who supervises from the floor. I cook dinner for five people every night.
When I test a sealing ring, I run it through a week of meals: a beef stew, a batch of steel-cut oats (yes, despite the manual), a curry, and then plain rice to see what flavor comes through.
I track how long the ring holds onto smells, how easy it is to clean, and whether it stretches out and loses its seal over time.
The most important thing I learned is that the ring is a consumable. It's not a buy-it-once-and-forget-it part. It absorbs fats and odors, and it eventually wears out. The question is when.
The Curry Ring Incident
I made a chicken curry in my 6-quart Instant Pot Duo on a Tuesday. I cleaned the pot normally, washed the ring with soap and water, and let everything dry. On Friday, I made a pot of plain jasmine rice for the kids. The rice tasted faintly of turmeric and garam masala.
That's the silicone ring's dirty secret. It's porous enough to absorb volatile flavor compounds, and no amount of regular dish soap gets them out. The Instant Pot manual warns about this, but you don't really understand it until you taste curry-flavored rice.
The fix is a vinegar soak. I fill a bowl with one part white vinegar and two parts water, drop the ring in for about twenty minutes, then rinse and air dry. That handles most of the odor. For stubborn smells, I've also thrown the ring in the top rack of the dishwasher, but I don't trust that completely.
The real fix is to own two rings and swap them. One for savory dishes like curry and chili, one for neutral things like rice and oatmeal. That's why the two-packs on this list exist.
Housewares Solutions Pack of 2
I bought this two-pack for my 6-quart Duo about a year ago, and it's the set I reach for most. The fit is snug, which is what you want. A loose ring won't seal properly and you'll get steam escaping from the sides instead of building pressure.
The rings are a bit stiff when they're new. The first time I used one, I had to work it into the lid and make sure it seated all the way around. After two or three cooks, it softened up and now it snaps in easily.
The odor absorption is the same as the OEM ring. I made a batch of chili and then plain rice the next day, and the rice picked up a hint of cumin. I did the vinegar soak and it was back to neutral.
My only real complaint is the stiffness. If you have arthritis or weak grip, these are harder to wrestle into the lid than the genuine Instant Pot rings. But for about ten bucks for two, they earn their spot in my drawer.
Instant Pot 2-Pack Sealing Ring Mini 3-Qt
This is the genuine OEM part for the 3-quart Mini. I own the 3-quart for sides and small batches, and I bought this two-pack specifically to dedicate one ring to savory and one to sweet.

The red and blue color coding is genuinely useful. I use the red ring for curries and anything with garlic, and the blue ring for rice and oatmeal. It's a simple system that completely solves the flavor transfer problem.
The fit is perfect, which you'd expect from the manufacturer. It seals tight, holds pressure, and doesn't stretch out. I've had these for about eight months and they still look and perform like new.
The downside is the price. You're paying a small premium for the brand name, but you're getting a guaranteed fit. If you own a 3-quart and you're tired of tasting last week's chili in your rice, this is the set to buy.
2 Pack Sealing Ring 8 Qt
My sister-in-law has the 8-quart Duo, and I bought her this two-pack when she complained about the same curry problem I had. I've used her cooker a few times since, and the rings have held up fine.
The food-grade silicone is the same material as the OEM rings. It seals well and doesn't impart any plastic taste to the food. The fit is good, maybe a hair looser than the genuine part, but it hasn't caused any pressure issues.
My hesitation is the material thickness. These rings feel slightly thinner than the OEM ones. That might mean they wear out faster, especially if you cook every day like I do. For the price, it's not a bad deal, but I'd plan on replacing these every six months to a year.
2 Pack Sealing Ring 3 Qt
I haven't tested this exact set in my own kitchen, but I've seen enough of these budget two-packs to know what you're getting. They're fine for the price. They seal, they hold pressure, and they'll absorb odors just like any other silicone ring.
The clear and blue color scheme is easy to tell apart, which is handy if you're running the dedicated-ring system. At this price, you can buy two sets and have four rings for less than the cost of one OEM pair.
My advice is to check the fit when they arrive. Budget rings sometimes have a slightly looser tolerance, and a ring that doesn't seat perfectly will cause slow pressure buildup. If they fit, they'll work. If they don't, send them back.
2-Pack Sealing Ring 3 Quart for Instant Pot Mini
Same story as the other budget Mini rings. I've seen this style of BPA-free silicone ring in a few different listings, and they all perform similarly. They seal fine, they absorb odors, and they need the same vinegar soak to stay neutral.
The one thing I'll say for this set is the price. If you're on a tight budget and you just need a spare ring for your 3-quart, this is the cheapest way to do it. It's not going to perform any better than the OEM ring, but it's not going to perform any worse either.
Steam Release Handle and Float Valve
This isn't a sealing ring, but it's part of the same conversation. The float valve and the steam release handle are the two parts that actually fail on a pressure cooker. I had a Ninja Foodi die on me after three years from a circuit board failure, but the mechanical parts are usually fine.
The float valve is the little pin that pops up when pressure builds. If it gets clogged with food residue, it won't seat properly and you'll lose pressure. The steam release handle is the part you twist for quick release, and it can get stuck if you don't clean it.
If your cooker is leaking steam or not building pressure, check these parts before you buy a new ring. A dirty float valve is a much more common problem than a worn-out ring.
When to Replace Your Sealing Ring
Here's the practical timeline. If you cook every day like I do, replace the ring every six to twelve months. If you cook a few times a week, you can stretch it to eighteen months.
The signs of a worn ring are easy to spot. The ring feels loose when you snap it into the lid. Steam escapes from the sides during cooking. The ring has visible cracks or has taken on a permanent yellowish tint.
The odor absorption is the first thing to go. After a few months, no amount of vinegar soaking will get the ring back to neutral. That's when you swap in the spare.
The Bottom Line
A sealing ring is a consumable part, not a permanent one. It absorbs flavors, it wears out, and it needs replacing on a schedule. The Housewares Solutions two-pack is the best value for the 6-quart models most people own, and the genuine Instant Pot two-pack is worth the premium if you want a guaranteed fit.
Don't wait until your rice tastes like curry to buy a spare. Buy a two-pack now, dedicate one ring to savory and one to sweet, and save yourself the disappointment. It earns its spot in the drawer.
