A worn or damaged sealing ring is a top cause of leaks and poor performance in Instant Pots. This guide covers how to spot when a new ring is needed, choose the right sealing ring replacement, and safely install it—so your cooker seals tightly and works like new.
Quick answer
Replace your Instant Pot sealing ring if there are leaks, strong odors, or the lid doesn’t seal. Choose the correct size and food-safe silicone. A new ring ensures proper pressurizing and safe cooking.
Signs you need a replacement part
Steam leaks around the lid during use
Persistent odors even after cleaning
Frequent BURN error codes
Not pressurizing or losing pressure
Loose, stretched, or cracked sealing ring
How to identify the correct part
1) Match your model number
Your Instant Pot model number is printed on a sticker or metal plate on the back or bottom of the cooker base. Check the model number before ordering parts—different models have rings or valves that may not fit each other.
2) Confirm quart size
Instant Pots most often come in 3-quart, 6-quart, or 8-quart sizes. Sealing rings and inner pots are not interchangeable between sizes. Measure your pot or check the box to confirm your quart size before buying any part.
3) Choose safe materials
The best instant pot sealing ring replacements are made of food-grade silicone, which is heat-resistant and safe for pressure cooking. Avoid parts made with questionable coatings or non-silicone plastics. Always check for FDA or food-safe certification.
4) Genuine vs third-party
Genuine Instant Pot parts are made to fit and are food-safe. Quality third-party rings can work well but always check sizing, reviews, and safety claims. Avoid unbranded parts and those with chemical odors or unclear materials.

FAQ
How often should I replace my Instant Pot sealing ring?

Why does my sealing ring smell?

Yes, if the ring is food-grade silicone and sized for your exact model and quart size.
What size sealing ring does my Instant Pot need?
Match the ring to your pot’s quart size—rings for 6-quart, 8-quart, and 3-quart models are not interchangeable.
