Installing the sealing ring on your Instant Pot might sound simple, but it’s a step many users overlook or get wrong. The sealing ring is a small, flexible silicone part that sits in the lid and plays a huge role in safe cooking. If it’s not installed properly, your Instant Pot can leak steam, fail to build pressure, or even stop working. In this guide, you’ll learn everything you need for a perfect sealing ring installation, even if you’re a complete beginner.
You’ll also discover why this step matters, how to avoid common mistakes, and how to keep your sealing ring in the best condition. By the end, you’ll have more confidence using your Instant Pot and know the small details that even experienced users sometimes miss.
What Is The Sealing Ring And Why Is It Important?
The sealing ring is a round silicone gasket that fits inside the Instant Pot lid. It creates an airtight seal so the cooker can build up steam pressure. Without a working sealing ring, your Instant Pot is just a regular pot with a fancy lid.
A good seal does three things:
- Keeps pressure inside: This means your food cooks faster and more evenly.
- Prevents leaks: No messy steam blowing out the sides.
- Ensures safety: The pressure stays under control, reducing the risk of accidents.
It’s important to check your sealing ring regularly. If it’s cracked, stretched, or smells bad, replace it. A worn ring can cause pressure problems and affect your food’s flavor.
Types Of Instant Pot Sealing Rings
Not all sealing rings are the same. They come in different sizes and materials, and using the wrong one can cause problems.
| Ring Size | Fits Pot Size | Material | Color Options |
|---|---|---|---|
| 8-inch | 3-quart | Food-grade Silicone | Clear, Red, Blue |
| 9-inch | 6-quart | Food-grade Silicone | Clear, Red, Blue |
| 10-inch | 8-quart | Food-grade Silicone | Clear, Red, Blue |
Always check your Instant Pot’s size before buying a new sealing ring. Many people buy a ring that’s too small or too big, and it won’t seal. The correct size is usually printed on your Instant Pot or in the manual.
Some users buy different colored rings to separate sweet and savory dishes. For example, use a blue ring for desserts and a red one for spicy foods. This prevents flavors from mixing—a detail many beginners miss.
When Should You Replace The Sealing Ring?
A silicone sealing ring lasts 12 to 18 months with regular use. However, certain signs tell you it’s time for a new one:
- Cracks or tears in the silicone
- A loose fit (the ring stretches out over time)
- Strong, unpleasant smells that don’t wash out
- Food not cooking properly (takes longer, doesn’t build pressure)
If you use your Instant Pot often—several times a week—consider replacing the sealing ring every 6-12 months. If you cook strong flavors (like curry or chili), smells can linger and affect other dishes. In this case, having two rings (one for savory, one for sweet) is a smart idea.
Never use a damaged ring. Pressure cookers need a perfect seal for safety.
Tools And Materials Needed
You don’t need special tools, but it helps to have:
- A new sealing ring (correct size for your pot)
- Dish soap and water (for cleaning before installation)
- A clean towel or paper towels
- Instant Pot lid (fully dry)
- Optional: Food-safe gloves (if you want to avoid fingerprints or smells)
Some people use a little vegetable oil to help slide the ring in, but this isn’t required and is not recommended by the manufacturer.

Preparing To Install The Sealing Ring
Before you install, clean your hands and the sealing ring. Even new rings can have a factory smell or residue. Wash it with warm, soapy water and dry it well.
Check the Instant Pot lid. Remove any old sealing ring, and clean out the ring’s groove with a damp cloth. Even small crumbs or oil can stop the ring from sealing.
Inspect the new ring for defects. Stretch it gently and look for cracks, tears, or thin spots. If you find any, ask for a replacement.
Step-by-step Guide: Installing The Sealing Ring
Follow these steps to install the sealing ring correctly. This process works for all standard Instant Pot models.
1. Remove The Old Sealing Ring
Find the old ring on the inside edge of the lid. Grip one side with your fingers and gently pull it out. Don’t use sharp tools—they can scratch the lid or damage the silicone.
If the ring is sticky or hard to remove, wiggle it side to side. If it’s stuck due to old food, soak the lid in warm, soapy water for 10 minutes.
2. Clean The Lid’s Groove
Wipe the inside groove where the ring sits. Even a tiny crumb can cause leaks. Use a damp cloth or paper towel. Dry it fully before adding the new ring.
3. Position The New Sealing Ring
Hold the new ring by its edge. Align it with the groove in the lid. Start on one side and press the ring into the groove with your thumbs.
4. Work The Ring Around The Lid
Move your fingers around the edge, pressing the ring into the groove. Make sure it sits flat and isn’t twisted. The ring should fit snugly, but not stretch too much.
Here’s a tip: Pull the ring gently as you go, but don’t force it. If it feels too tight, double-check that you have the correct size.
5. Check For A Proper Fit
After the ring is installed, run your finger around the edge. It should be smooth and flat all the way around. No part should stick out or be bunched up.
Flip the lid over and look at the ring from both sides. It should fill the groove evenly.
6. Test The Seal
Before cooking, run a “steam” cycle with water only (sometimes called a water test). This checks for leaks and helps seat the ring.
- Add 2 cups of water to the inner pot.
- Close the lid and set the valve to “Sealing.”
- Run the “Steam” function for 2 minutes.
If you see steam escaping around the lid, the ring may not be installed correctly. Stop the cycle, let the pot cool, and check the ring’s fit again.
Troubleshooting Common Problems
Even with the right steps, things can go wrong. Here’s how to fix common sealing ring problems:
The Ring Won’t Stay In Place
If the ring pops out, it may be the wrong size. Compare your ring to the old one. If it’s much bigger or smaller, get the correct size.
The Ring Smells Bad
Some foods (like onions or curry) can leave smells in the silicone. Wash the ring with baking soda and water, or run it through the dishwasher. If the smell remains, consider using separate rings for different foods.
The Instant Pot Won’t Pressurize
If your pot doesn’t reach pressure:
- Check if the ring is seated fully and isn’t twisted.
- Make sure the float valve and steam release are clean and not blocked.
- Confirm the ring isn’t damaged or too loose.
If everything looks fine, try the water test again.
The Ring Looks Stretched
A stretched ring won’t seal well. Over time, silicone expands with heat. If the ring is loose, it’s time to buy a new one.
How To Care For Your Sealing Ring
A well-cared-for sealing ring lasts longer and works better. Here’s how to keep yours in top shape:
- Clean after every use: Wash with hot, soapy water. Dry fully before reinstalling.
- Avoid strong smells: Store the lid upside down or off the pot to let air circulate.
- Dishwasher safe: Most rings can go on the top rack of the dishwasher.
- Store spares separately: Keep extra rings in a clean, dry place.
Never use harsh chemicals or rough scrubbers. These can damage the silicone and cause leaks.

Pro Tips For Installing And Maintaining The Sealing Ring
Some Instant Pot users don’t realize these simple tricks:
- Freeze the ring for 10 minutes before installation. Cold silicone is firmer and easier to install.
- Rotate your rings. Alternate between two rings to let each one “rest” between uses. This extends their life.
- Mark the install date on the ring with a permanent marker. This helps you remember when to replace it.
If you cook both sweet and savory dishes, buy two rings and use different colors. This keeps desserts from tasting like garlic or curry.
Sealing Ring Compatibility: Which Models Use Which Rings?
Each Instant Pot model requires a specific ring size. Using the wrong ring can cause leaks or safety issues. Here’s a quick comparison:
| Instant Pot Model | Pot Size | Ring Size Needed |
|---|---|---|
| Duo Mini | 3-quart | 8-inch |
| Duo, Duo Plus, Lux, Ultra, Viva | 6-quart | 9-inch |
| Duo Nova, Duo Evo Plus | 6-quart, 8-quart | 9-inch, 10-inch |
| Duo Crisp | 8-quart | 10-inch |
Always double-check your Instant Pot model and size before buying a new sealing ring.

How To Remove And Replace The Sealing Ring Safely
Changing the sealing ring is simple, but safety matters. Here’s how to do it right:
- Wait until the lid is cool: Never remove the ring while the lid is hot.
- Use clean hands: Oils and dirt can damage the silicone.
- Work gently: Pull the ring out slowly. Don’t use sharp tools.
- Store removed rings flat: Don’t fold or twist them. This keeps their shape.
If you have trouble removing a stuck ring, soak the lid in warm water. This softens the silicone and makes removal easier.
Cleaning Tips For Sealing Rings
Many users struggle with cleaning, especially after cooking strong-smelling foods. Try these methods:
- Dishwasher: Put the ring on the top rack. Run a normal cycle.
- Baking soda paste: Mix baking soda with water, rub on the ring, and rinse.
- Vinegar soak: Soak the ring in a mix of white vinegar and water for 15 minutes.
- Sunlight: Leave the clean ring in the sun for a few hours. Sunlight helps remove smells.
Never use bleach or harsh chemicals. They can damage the silicone and make the ring unsafe for cooking.
How To Store Sealing Rings
Proper storage keeps your sealing rings in good shape and prevents smells.
- Let the ring air out: Store the Instant Pot lid upside down or off the pot. This lets air move around the ring.
- Store extra rings in zip-top bags: Keep them in a cool, dry place away from direct sunlight.
- Do not fold or twist: Folding can cause cracks or weak spots.
Some users store rings in the freezer to reduce smells. This is safe, but always let the ring warm to room temperature before installing.
What To Do If Your Instant Pot Leaks Steam
A leaking Instant Pot is frustrating and can ruin dinner. Here’s how to troubleshoot:
- Check the sealing ring: Is it seated properly? Is it the correct size? Is it damaged?
- Check the lid: Is it locked in place?
- Inspect the float valve and steam release: Are they clean and working?
- Try a water test: If you see steam leaking, stop the cycle, wait for the pot to cool, and check the ring again.
Most leaks are caused by a misaligned or damaged sealing ring. If you can’t fix the problem, contact Instant Pot support.
How To Tell If The Sealing Ring Is Installed Correctly
There are a few easy tests:
- Visual check: The ring should sit flat in the groove with no twists or bunches.
- Feel test: Run your finger around the ring. It should feel smooth and even.
- Pressure test: Run a water-only cycle. If the pot comes to pressure and no steam leaks, the ring is installed correctly.
Small mistakes—like a twisted ring or a crumb in the groove—can stop the Instant Pot from working.
How The Sealing Ring Affects Cooking Performance
The sealing ring isn’t just about safety. It also affects how your Instant Pot cooks:
- Better pressure: A good seal means faster cooking and better results.
- Even heating: Steam stays inside, so food cooks evenly.
- No flavor leaks: Smells and flavors stay in the pot, not your kitchen.
If your food is taking longer to cook or comes out dry, check the sealing ring first.
When To Get Help Or Contact Support
Sometimes, a sealing ring issue is part of a bigger problem. Get help if:
- The ring won’t fit, even after checking the size.
- The Instant Pot shows error codes (like “Lid” or “NoPr”).
- You see cracks or chips in the lid.
Contact Instant Pot customer support for advice. You can also find official guides on the Instant Pot website or check their user forums for tips.

Sealing Ring Myths And Mistakes
Many users believe common myths. Here’s the truth:
- Myth: You need to oil the ring for a better seal.
- Fact: Silicone seals naturally. Oil is not required and may damage the ring.
- Myth: One ring is enough for all foods.
- Fact: Strong smells can stay in the ring. Use different rings for sweet and savory dishes.
- Myth: Any silicone ring will fit.
- Fact: Only use rings made for your Instant Pot model and size.
Avoid these mistakes for safer, better cooking.
How To Buy Genuine Sealing Rings
Counterfeit sealing rings are common, especially on online marketplaces. They may not be food-safe or fit correctly.
Tips for buying genuine rings:
- Buy from the official Instant Pot website or trusted retailers.
