How to Replace a Kamado Gasket

The felt gasket on your kamado grill is what creates the airtight seal that makes temperature control possible. Over time, it compresses, tears, and loses its seal. When you notice temperature swings or can't hold low temps, it's gasket time. Here's the full replacement process.

Tools & Materials

  • Replacement gasket kit (brand-specific recommended)
  • Gasket adhesive
  • Putty knife or scraper
  • Rubbing alcohol
  • Clean rags

Step by Step

1

Remove the old gasket

Open the lid fully. Peel off the old gasket from both the lid and the base. Use a putty knife to scrape off remaining adhesive. Take your time — rushing creates an uneven surface for the new gasket.

2

Clean the surfaces

Wipe both gasket channels with rubbing alcohol to remove all residue, grease, and debris. The surface needs to be perfectly clean for the new adhesive to bond properly.

3

Dry-fit the new gasket

Before applying adhesive, lay the new gasket in place to plan your alignment. Note where the gasket starts and ends — you want a clean butt joint, not an overlap.

4

Apply adhesive and set the gasket

Apply gasket adhesive in the channel. Press the gasket firmly into place, starting at the back and working forward. Press down evenly every few inches to ensure consistent contact.

5

Let it cure

Leave the lid open and allow the adhesive to cure for 24 hours before closing or firing. Closing too early can compress the gasket before the adhesive sets.

6

Test the seal

Close the lid and check for even contact all the way around. Light a small fire and close down the vents — the fire should choke out within minutes if the seal is good.

Warnings

  • Don't use generic gasket material — kamado gaskets need to handle 700°F+ temperatures. Use the manufacturer's kit or a high-temp aftermarket option.
  • Don't close the lid until the adhesive has fully cured — you'll end up with a permanently compressed, uneven gasket.
  • If your kamado has a cracked firebox, a new gasket won't fix temperature control issues. Inspect for cracks before replacing the gasket.

How Often?

Every 1-3 years depending on use frequency. Check the seal regularly — if you can see daylight through the closed lid, it's time.
