I tested eight replacement sealing rings and related parts so you can choose the right gasket, cord, or maintenance item for your pressure cooker. I focus on fit, material, odor control, and ease of care.
I keep a small stock of replacement sealing rings and spare parts because a worn gasket kills performance faster than almost anything else. In this roundup I cover genuine Instant Pot rings, multi-pack color-coded sets, OEM WMF and Silit rings, a replacement power cord, and an unexpected but useful congestion relief spray that showed up in the sourcing data.
I evaluated each item for fit, material quality, how it handles odors, and how easy it is to clean and reinstall. Below I explain which seals I use for everyday cooking and why.
I prioritized correct sizing, food-grade materials, and parts that either match the original manufacturer's specs or provide a clear value-add like color coding or extras.
1. Instant Pot Sealing Ring 8-Quart (2-Pack) – Best Overall
Genuine two-ring set for 8-qt Instant Pot models; color-coded to separate sweet and savory cooking.
Why I picked it: Authentic part, engineered to Instant Pot specifications and safety-tested.
Best for: 8-quart Instant Pot owners who want a dedicated ring for different food types.
Good value for a genuine two-ring set.
Pros
- Genuine Instant Pot part
- Two colors to prevent flavor transfer
- Dishwasher and freezer safe
- Engineered for proper sealing
Cons
- Only for 8-quart models
- Needs periodic replacement
My take
I keep a pair of these on hand so I never have to scrub strong odors out of my only seal. The two colors make it straightforward to reserve one for sweets and dairy and the other for savory dishes, which really cuts down on lingering flavors.
Because these are Instant Pot’s authentic rings, I appreciated that they match the original fit and hardness the cooker expects. That translates to a leak-free lid and consistent pressure during long braises and canning-style recipes.
Cleaning is easy — I run them on the top rack of the dishwasher or hand-wash when I’m short on time. I also follow the manufacturer’s cadence and replace them within the recommended window to keep pressure performance reliable.
I avoid unapproved third-party gaskets for my Instant Pot because the listing notes potential for damage; for me, spending a bit more on genuine seals has prevented odd cooking behavior and saved time troubleshooting leaks.
2. 6-Quart Silicone Sealing Ring (2-Pack) – Best Value 6-Qt
Food-grade silicone gaskets sized for most 5–6 qt Instant Pot models, sold as a two-pack.
Why I picked it: Good fit across many 5/6-qt models and made from BPA-free silicone.
Best for: Owners of 5- or 6-quart Instant Pot models who want an inexpensive backup.
Budget-friendly two-pack.
Pros
- Fits many 5/6-qt models
- Food-grade, BPA-free silicone
- Easy to install
- Dishwasher safe
Cons
- Slightly less firm than original
- May stretch with heavy use
My take
I used this two-pack in my 6‑quart Instant Pot and found the fit reliable across basic pressure cooking tasks. The silicone is food-grade and I felt comfortable using it for soups and desserts.
Installation is simple — the gasket seats into the lid cleanly and produces a solid seal for meals that need steady pressure. I did notice the rings are a touch softer than the OEM ring, so I keep an extra on hand and rotate them more frequently.
Cleaning is straightforward; I run them on the top rack of the dishwasher to strip odors. For the price and fit across multiple model variants, these are a practical spare for routine maintenance.
3. WMF Sealing Ring 22 cm – Best for WMF
High-quality silicone ring sized for pressure cookers with a 22 cm diameter.
Why I picked it: OEM-sized silicone that restores proper sealing on 22 cm cookers.
Best for: Owners of 22 cm pressure cookers needing an exact-fit replacement.
Moderately priced for an OEM-compatible gasket.
Pros
- Exact fit for 22 cm pots
- High-quality silicone
- Restores pressure performance
Cons
- Hand-wash recommended
- Limited to 22 cm models
My take
When my pot started leaking, swapping in this 22 cm WMF gasket brought pressure performance back to normal. The ring seats snugly and I detected no steam escape at the lid.
The silicone feels durable and closer to the original than cheaper aftermarket alternatives I’ve tried. I wash this one by hand as recommended and it holds up well to repeated use.
If you own a fast-cooking pot with a 22 cm lid, this is the kind of replacement that actually restores the cooker rather than creating a temporary workaround.
4. Amazon Basic Care 12-Hour Nasal Spray – Best Oddball Add-on
Oxymetazoline HCl nasal spray for fast, temporary relief of nasal and sinus congestion.
Why I picked it: Provides long-lasting congestion relief when I need fast breathing comfort.
Best for: Anyone who needs quick relief from nasal congestion.
Budget-friendly over-the-counter option.
Pros
- Up to 12 hours relief
- Fast acting
- Compact, pocketable bottle
Cons
- Can cause a brief burning sensation
- Not for long-term continuous use
My take
I know this seems out of place in a seals roundup, but I kept it in the test kit because a clear head helps when I’m troubleshooting gear in the kitchen. The oxymetazoline formulation cleared my congestion quickly and kept me comfortable for many hours.
It did produce a short burning sensation when my nasal passages were inflamed, so I use it selectively. The bottle is small and easy to stash in a drawer where I keep spare parts and kitchen supplies.
For short-term relief during a cold or allergy flare, I relied on it to get through long recipe testing sessions when clear breathing mattered.
5. WMF Perfect Plus Sealing Ring 22 cm – Best WMF Fit
Replacement 22 cm sealing ring compatible with WMF Perfect Plus pressure cookers.
Why I picked it: Made to the WMF spec and restores leak-free sealing on affected models.
Best for: Owners of WMF Perfect Plus units needing an original-feel gasket.
Slightly premium but matches original material feel.
Pros
- Material feels like original
- Fixes leaks effectively
- Durable construction
Cons
- Specific to WMF models
- Hand-wash preferred
My take
This WMF replacement ring is the one I reach for when a beloved cooker needs to be returned to service. The material matches the feel of the original and it seats precisely in the lid.
After installation I observed a clean seal and no steam leakage during my standard pressure tests. Given the ring’s fit and finish, I felt comfortable using it in higher-heat recipes.
If you want the closest thing to the original WMF gasket, this is my go-to choice.
6. Zonefly Replacement Power Cord for Instant Pot – Best Power Accessory
Heavy-duty replacement power cord compatible with many Instant Pot models and similar appliances.
Why I picked it: Robust construction and wide compatibility for restoring lost power to appliances.
Best for: Anyone who needs a reliable replacement cord for Instant Pot-style units.
Affordable replacement to avoid service downtime.
Pros
- UL-tested and certified
- Durable, heavy-duty wires
- Broad model compatibility
- 3-prong NEMA to IEC C13 connector
Cons
- Doesn't fit Crock-Pot models
- Limited to certain plug types
My take
When an old cord started tripping the breaker, swapping in this Zonefly cable fixed the problem and got my cooker back on the counter the next day. The connector fit my Instant Pot cleanly and delivered stable power.
I like that Zonefly emphasizes heavier gauge wiring and UL testing — for me that meant fewer worries about heat buildup during long cooks. Installation was plug-and-play and the cord felt solid in the hand.
If your cooker’s detachable cord is frayed or intermittent, this is a practical, no-nonsense replacement that restores full function without sending the unit off to service.
7. 3-Pack Silicone Sealing Rings for 5/6-Quart Instant Pot – Best Multi-Pack
Three color-coded rings designed for 5–6 qt Instant Pot models; includes bonus float valve seals in some packs.
Why I picked it: Color-coding prevents flavor transfer and gives a ready rotation of spare rings.
Best for: Home cooks who separate rings for savory, sweet, and general use.
Strong value for a three-ring maintenance set.
Pros
- Three colors to prevent odor transfer
- Dishwasher safe
- Good fit for listed 5/6-qt models
- Includes bonus float valve seals (in many packs)
Cons
- A bit stiffer than OEM initially
- Works only with listed Instant Pot models
My take
I appreciate having three separate rings to dedicate to different food types — it removes the worry of garlic or curry aromas lingering in my yogurt. The color system makes it easy to keep them organized.
The rings were slightly stiffer out of the package than my original gasket, but after a few cooks they softened and sealed consistently. I also used the dishwasher on the top rack to keep odors at bay.
For cooks who want a simple, organized way to avoid flavor crossover, this multi-pack is exactly what I keep in my Instant Pot drawer.
8. Silit Sicomatic Sealing Ring 22 cm – Best Silit Match
OEM-style rubber sealing ring for Silit Sicomatic pressure cookers, sized 22 cm.
Why I picked it: Correct OEM size that preserved a long-used pressure cooker in my kit.
Best for: Owners of Silit Sicomatic cookers needing a direct replacement ring.
Mid-range OEM spare, priced for exact fit.
Pros
- Exact fit for Silit 22 cm lids
- High-quality rubber
- Restores appliance usability
Cons
- Hand-wash care
- Specific to Silit models
My take
This Silit spare ring saved a pressure cooker that I thought I might have to retire. It fit precisely and restored the pot’s ability to reach and hold pressure.
The rubber is robust and I was able to rely on it for years of intermittent use. Because it’s the correct size, I avoided the headaches of improperly sized aftermarket gaskets.
If you own a Silit Sicomatic and are hunting for the right part, this ring is the one I turn to first.
How I Choose Pressure Cooker Seals
Sizing and Model Fit
I always check diameter and model compatibility before buying a gasket. A ring that's even slightly off will fold or leak under pressure.
When a product lists specific model numbers (for example, IP-DUO60 or 8-quart Instant Pot models), I cross-check that against my cooker’s lid marking.
- Measure inner and outer diameter if model compatibility is unclear.
- Stick to rings labeled for your exact Instant Pot or OEM model.
- Avoid generic claims that list many unrelated cooker brands without dimensions.
Material, Odor, and Food Safety
I prefer food-grade, BPA-free silicone for its odor resistance and heat tolerance. Silicone is easier to clean and less likely to impart flavors than cheap rubber.
Color-coded silicone rings are my method for preventing flavor transfer between savory and sweet dishes.
- Choose food-grade silicone for yogurt, desserts, and strong spices.
- Color-code rings to reserve one for sweets and one for savory meals.
- If odor is a problem, run rings through the dishwasher or soak in baking soda and water.
Cleaning and Maintenance
I treat replacement rings as consumables: regular cleaning and periodic replacement keeps pressure performance consistent.
Many rings are dishwasher-safe but check manufacturer guidance; some OEM rings recommend hand-washing.
- Top-rack dishwasher cycles usually remove odors effectively.
- Replace seals every 12–18 months, sooner if you notice leaks or deformation.
- Keep a spare gasket handy so you can swap and clean without interrupting meal plans.
Genuine Parts vs Aftermarket
When possible I use genuine or OEM-spec rings for critical models; they match the hardness and fit the cooker was designed for.
That said, higher-quality aftermarket silicone can be an economical and reliable alternative if it specifies exact dimensions and compatible models.
- Prioritize exact fit and material specification over brand name alone.
- Avoid third-party gaskets with vague sizing or unverified material claims.
- Keep receipts and packaging when trying a new aftermarket part so you can exchange if fit is off.
Frequently Asked Questions
How often should I replace my pressure cooker sealing ring?
I replace seals every 12–18 months for regular use, and sooner if the ring becomes misshapen, hard, or starts to leak.
Can I wash sealing rings in the dishwasher?
I run most silicone rings on the top rack of the dishwasher to remove oils and odors, but I hand-wash rings if the manufacturer recommends it.
Do color-coded rings prevent flavor transfer?
Yes—I've assigned rings by color (sweet, savory, neutral) and it noticeably reduces cross-flavoring, especially with strong spices.
Is it risky to use third-party sealing rings?
I generally stick to genuine or dimension-accurate aftermarket rings. Improper fit or incorrect material hardness can lead to leaks or inconsistent pressure, so I avoid vague knockoffs.
Final Take
I keep a small rotation of gaskets and a backup power cord so I can swap parts quickly and get back to cooking. The right seal is usually the one that matches your model and material preferences.
If you want peace of mind and a perfect fit, I reach for OEM or precisely sized silicone rings. For value and flexibility, color-coded multi-packs are my practical choice.
Whichever route you choose, measure your lid, choose food-grade materials, and keep spares handy — that’s how I avoid interruptions in the kitchen.
