The gasket creates an airtight seal that regulates airflow, maintains consistent cooking temperatures, and protects the ceramic edges from direct contact and potential chipping.\u003cbr\u003e\u003c\/p\u003e\n\u003cp\u003eThe felt gasket material is installed on the upper edge of the ceramic base and the lower edge of the ceramic dome. Over time and intensive use, this felt wears out, compresses, or deteriorates from exposure to high heat, moisture, and repeated dome openings and closings. When the gasket deteriorates, the seal becomes compromised, leading to air leaks that make temperature control difficult and reduce fuel efficiency.\u003cbr\u003e\u003c\/p\u003e\n\u003cp\u003eThe High Performance Gasket Kit features self-adhesive felt that bonds directly to the cleaned ceramic surface without requiring separate adhesive. The felt material withstands temperatures up to 330°C (625°F), which exceeds the typical operating temperature range for most Big Green Egg cooking methods.\u003cbr\u003e\u003c\/p\u003e\n\u003cp\u003eThe kit includes sufficient felt material to replace gaskets on both the dome and base. The gasket is easy to install for DIY replacement, requiring only basic tools (scraper or putty knife for old gasket removal) and cleaning supplies (isopropyl alcohol or acetone for residue removal).\u003cbr\u003e\u003c\/p\u003e\n\u003cp\u003eTwo kit sizes are available: one for MiniMax, Small, and Medium EGGs (part number 113733), and one for Large, XL, and 2XL EGGs (part number 113726). The 2XL model requires two Large\/XL kits due to its larger circumference.\u003cbr\u003e\u003c\/p\u003e\n\u003cp\u003eWe stock both sizes of the Big Green Egg High Performance Gasket Kit at our Wetherill Park showroom alongside our full range of Big Green Egg replacement parts and maintenance accessories.\u003c\/p\u003e\n\u003ch2\u003eKey Features\u003cbr\u003e\n\u003c\/h2\u003e\n\u003ch3\u003eRestores Airtight Seal for Precise Temperature Control\u003cbr\u003e\n\u003c\/h3\u003e\n\u003cp\u003eThe primary function of the felt gasket is creating an airtight seal between the dome and base. This seal controls airflow through the EGG, which directly determines cooking temperature. When the gasket is intact, you can precisely regulate temperature by adjusting the top and bottom vents. Air enters through the bottom vent, flows through the charcoal, and exits through the top vent, with the sealed dome preventing uncontrolled air leaks.\u003cbr\u003e\u003c\/p\u003e\n\u003cp\u003eA worn or damaged gasket allows air to leak around the dome perimeter, bypassing the vent controls. These leaks make it difficult to maintain low smoking temperatures (110-135°C) because you cannot fully restrict airflow. Temperature becomes unstable and tends to run hotter than desired, compromising low-and-slow cooking results.\u003cbr\u003e\u003c\/p\u003e\n\u003cp\u003eReplacing the gasket with the High Performance Gasket Kit restores the airtight seal, returning precise vent control and temperature stability. This is particularly important for overnight cooks or competition smoking where maintaining steady temperature for 12-16 hours is critical.\u003cbr\u003e\u003c\/p\u003e\n\u003ch3\u003eHeat-Resistant Felt Material Rated to 330°C\u003cbr\u003e\n\u003c\/h3\u003e\n\u003cp\u003eThe gasket felt is manufactured from heat-resistant material rated to withstand temperatures up to 330°C (625°F). This temperature rating provides a safety margin above typical Big Green Egg cooking temperatures:\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eLow-and-slow smoking: 110-135°C\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003eRoasting: 175-200°C\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003eHigh-heat grilling: 260-290°C\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003ePizza baking: 315-370°C (above gasket rating, but gasket location away from direct heat provides protection)\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eThe felt material retains its sealing properties and structural integrity across this temperature range. Unlike lower-quality replacement gaskets that may compress excessively or become brittle when exposed to repeated high-heat cycles, the High Performance felt maintains consistent thickness and flexibility.\u003cbr\u003e\u003c\/p\u003e\n\u003cp\u003eThe material also resists moisture absorption, which is important because kamado cooking produces steam from food. Moisture-resistant felt prevents the gasket from swelling when wet or becoming brittle when dried.\u003cbr\u003e\u003c\/p\u003e\n\u003ch3\u003eSelf-Adhesive Installation Requires No Additional Glue\u003cbr\u003e\n\u003c\/h3\u003e\n\u003cp\u003eThe felt gasket features self-adhesive backing that bonds directly to cleaned ceramic surfaces. This eliminates the need to purchase separate high-temperature adhesive and simplifies the installation process. The adhesive is specifically formulated for ceramic surfaces and high-temperature applications.\u003cbr\u003e\u003c\/p\u003e\n\u003cp\u003eProper surface preparation is critical for good adhesion. The ceramic rim must be thoroughly cleaned to remove all traces of old gasket material, adhesive residue, grease, and dust. Use a scraper or putty knife to remove the old gasket, then clean the surface with isopropyl alcohol or acetone to ensure the new gasket adheres properly.\u003cbr\u003e\u003c\/p\u003e\n\u003cp\u003eThe self-adhesive backing includes a protective liner that you peel away as you apply the felt, allowing you to position the gasket carefully around the curved ceramic rim without the felt sticking prematurely.\u003cbr\u003e\u003c\/p\u003e\n\u003ch3\u003eProtects Ceramic Edges from Chipping\u003cbr\u003e\n\u003c\/h3\u003e\n\u003cp\u003eBeyond temperature control, the felt gasket provides a cushion between the ceramic dome and base. This cushioning protects the ceramic edges from direct contact, which can cause chipping or cracking over time.\u003cbr\u003e\u003c\/p\u003e\n\u003cp\u003eCeramic is extremely durable under heat but can chip or crack from impact. Without a gasket, closing the dome creates ceramic-to-ceramic contact at high temperatures. The thermal stress combined with mechanical force increases the risk of edge damage.\u003cbr\u003e\u003c\/p\u003e\n\u003cp\u003eThe compressible felt absorbs impact energy when you close the dome, distributing the force evenly around the circumference rather than concentrating it at hard contact points. This extends the life of your ceramic shell and prevents costly damage that would require warranty claims or shell replacement.\u003c\/p\u003e\n\u003ch2\u003eSpecifications\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eMaterial - Heat-resistant felt with self-adhesive backing\u003c\/li\u003e\n\u003cli\u003eTemperature Rating - Up to 330°C (625°F)\u003c\/li\u003e\n\u003cli\u003eInstallation - Self-adhesive, no separate glue required\u003c\/li\u003e\n\u003cli\u003e2XL Requirement - Two kits\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eWhat's Included\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e1 x Big Green Egg High Performance Gasket Kit (sufficient felt for both dome and base gaskets)\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003eSelf-adhesive felt material\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003eInstallation instructions\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eHow to Use\u003cbr\u003e\n\u003c\/h2\u003e\n\u003ch3\u003eRemoving the Old Gasket\u003c\/h3\u003e\n\u003cp\u003eBefore installing the new gasket, completely remove the old gasket material and adhesive residue from both the dome and base ceramic rims. Use a scraper, putty knife, or razor blade to carefully scrape away the old felt. Work slowly to avoid scratching or damaging the ceramic surface.\u003cbr\u003e\u003c\/p\u003e\n\u003cp\u003eFor stubborn adhesive residue, apply isopropyl alcohol or acetone to soften the adhesive, then scrape it away. Continue until the ceramic rim is completely clean and smooth. Any remaining residue will prevent the new gasket from adhering properly.\u003cbr\u003e\u003c\/p\u003e\n\u003cp\u003eEnsure the EGG is completely cool and dry before beginning gasket removal. Never attempt gasket replacement on a warm EGG.\u003cbr\u003e\u003c\/p\u003e\n\u003ch3\u003eInstalling the New Gasket\u003cbr\u003e\n\u003c\/h3\u003e\n\u003cp\u003eWipe the cleaned ceramic rims with isopropyl alcohol and allow them to dry completely (5-10 minutes). Starting at the hinge area, peel back a short section (10-15cm) of the protective liner from the adhesive backing. Position the felt on the ceramic rim and press it firmly into place.\u003cbr\u003e\u003c\/p\u003e\n\u003cp\u003eContinue working around the circumference, peeling back the liner gradually as you go and pressing the felt firmly against the ceramic. Ensure the felt follows the curve of the rim smoothly without wrinkles or gaps. When you reach the starting point, cut the felt to butt against the beginning section without overlap.\u003cbr\u003e\u003c\/p\u003e\n\u003cp\u003eRepeat the process for both the dome gasket and the base gasket. The base gasket goes on the upper edge of the base (where the dome rests). The dome gasket goes on the lower edge inside the dome.\u003cbr\u003e\u003c\/p\u003e\n\u003ch3\u003eCuring the Adhesive\u003cbr\u003e\n\u003c\/h3\u003e\n\u003cp\u003eAfter installation, allow the adhesive to cure before using the EGG. Close the dome gently and let the EGG sit for 2-4 hours to allow the adhesive bond to strengthen.\u003cbr\u003e\u003c\/p\u003e\n\u003cp\u003eFor the first cook after gasket replacement, use moderate temperatures (175-200°C) rather than high heat. This allows the adhesive to fully cure under gentle heat. Avoid slamming the dome or creating excessive stress on the new gasket during this break-in period.\u003cbr\u003e\u003c\/p\u003e\n\u003cp\u003eAfter the first moderate-temperature cook, the gasket is fully cured and ready for normal use at any temperature within its rating.\u003c\/p\u003e\n\u003ch2\u003eCare and Maintenance\u003cbr\u003e\n\u003c\/h2\u003e\n\u003cp\u003eAvoid slamming the dome, as repeated impact stress can compress the felt gasket prematurely and shorten its lifespan. Close the dome gently rather than dropping it from height.\u003cbr\u003e\u003c\/p\u003e\n\u003cp\u003eClean gasket surfaces periodically by wiping with a damp cloth to remove grease and food residue that can accumulate on the felt. Do not use harsh chemicals or solvents on the installed gasket, as these may degrade the felt or adhesive.\u003cbr\u003e\u003c\/p\u003e\n\u003cp\u003eInspect the gasket annually for signs of wear, compression, or deterioration. Common signs that gasket replacement is needed include visible gaps when the dome is closed, difficulty maintaining low temperatures, excessive fuel consumption, or felt that has become thin, hard, or brittle.\u003cbr\u003e\u003c\/p\u003e\n\u003cp\u003eStore unused gasket kit in a cool, dry location away from direct sunlight. The self-adhesive backing can deteriorate if exposed to heat or moisture before installation.\u003c\/p\u003e\n\u003ch2\u003eFrequently Asked Questions\u003cbr\u003e\n\u003c\/h2\u003e\n\u003ch3\u003eHow do I know when my gasket needs replacement?\u003cbr\u003e\n\u003c\/h3\u003e\n\u003cp\u003eSigns include difficulty maintaining low smoking temperatures, excessive fuel consumption, visible gaps between dome and base when closed, felt that appears compressed, worn, or deteriorated, or soot marks on the outer ceramic shell (indicating air leaks).\u003cbr\u003e\u003c\/p\u003e\n\u003ch3\u003eCan I replace just the dome gasket or just the base gasket?\u003cbr\u003e\n\u003c\/h3\u003e\n\u003cp\u003eThe kit includes sufficient material for both gaskets and Big Green Egg recommends replacing both simultaneously. If only one gasket is worn, you can technically replace just that one, but replacing both ensures consistent sealing performance.\u003cbr\u003e\u003c\/p\u003e\n\u003ch3\u003eWhat tools do I need for installation?\u003cbr\u003e\n\u003c\/h3\u003e\n\u003cp\u003eYou need a scraper or putty knife for removing old gasket, isopropyl alcohol or acetone for cleaning residue, clean rags, and scissors or a sharp knife for cutting the felt to length. No special tools or high-temperature adhesive are required.\u003cbr\u003e\u003c\/p\u003e\n\u003ch3\u003eHow long does gasket replacement take?\u003cbr\u003e\n\u003c\/h3\u003e\n\u003cp\u003eMost EGG owners complete gasket replacement in 1-2 hours, including old gasket removal, surface cleaning, and new gasket installation. The most time-consuming step is thoroughly removing old adhesive residue.\u003cbr\u003e\u003c\/p\u003e\n\u003ch3\u003eHow long will the new gasket last?\u003cbr\u003e\n\u003c\/h3\u003e\n\u003cp\u003eUnder normal operating conditions, the High Performance gasket lasts for years. Lifespan depends on usage frequency, temperature ranges, and dome handling (gentle closing extends gasket life compared to repeated slamming).\u003cbr\u003e\u003c\/p\u003e\n\u003ch3\u003eCan I use the EGG immediately after installing the new gasket?\u003cbr\u003e\n\u003c\/h3\u003e\n\u003cp\u003eAllow 2-4 hours for the adhesive to cure before the first use.
