Gold Standard High Heat Gasket with Adhesive for Large Big Green Egg with Kevlar and Nomex - 2yr Warranty

I bought this gasket after I burned my second factory Primo gasket making a pizza on my Kamado grill. This product was as described and was shipped quickly. The quality of the gasket seems to be there and installation was a breeze. This gasket has the adhesive already on the back with a peel-away strip that you remove when you are ready to place the gasket. I had no trouble installing the gasket. So far it has performed well, I have yet to do a high temp pizza bake though, and will update my review with the results when I do.A few notes:1) Be sure to clean the rim of your Primo well before installation. This is important to ensure that this gasket has a good bond to the grill. The best way to do this is to get a scraper and scrape your old gasket off. Then I used some fine sandpaper to get any other grit/fiber off of the rim. Lastly, use some acetone and a cloth to remove any residual adhesive from the last gasket off of the grill and let the rim dry.2) This gasket does NOT need to be 'pre-shrunk' in the dryer. If you attempt to do this you will most likely ruin the adhesive on the back and probably your dryer as well. This is not like other gaskets that have a separate adhesive and can be pre-shrunk prior to installation.I will attempt to update this review as I continue to grill to comment on the durability and 'high heat resistance' of this gasket.UPDATE 7/27/13 - This gasket is still running strong. I have done many low and slow as well as high heat cooks and the gasket still adheres well and has not burnt up like the factory gasket did. More than likely the biggest reason people have trouble with the gasket adhering is because they did not clean the grill correctly. Be sure to use the scraper/sandpaper/ and acetone.I would still give this gasket 5 stars.

Bought the product after the original gasket became flattened and hard. I noticed I couldn't keep my smoking temps down below 300 as I no longer had a good seal. I decided to try this product because I was disappointed the original gasket did not last very long - about a year and a half. Removing the old gasket was labor intensive and time consuming. After using razor blades and paint scrapers to get most of the old gasket off I was left with the adhesive residue which turned out to be the most difficult part to remove. After trying many different methods I ended up using very coarse sand paper to clean off the rest of the gasket residue. Had I known to use the sand paper I would have reduced the removal time of the old gasket from about 2.5 hours by about an hour. Using the sand paper I was able to get my egg perfectly clean with no discoloring left on the ceramics. I believe this is essential getting a new gasket to adhere properly and last a long time. A final wipe with acetone completed the job and the new gasket was very easy to apply with the adhesive backing following the instructions. 1 year later the gasket works perfectly after heavy use and is holding up much better than the original. I've had my egg up to 625 degrees and no problems yet. An advantage I discoverd over the original gasket is when liguids are dripped or spilled on the new gasket it does not seem to absorb them. I think this helps with longevity as I noticed spilled liguids on the original gasket would cause it to harden and shrink and it would not conform to the other side of the gasket in those areas. This gasket does not do that and remains soft and conforms to create a good air tight seal. After spending a couple of hours cleaning off the old gasket I want make sure I use the best replacement gasket and spend the least amount of time repeating that task. This is a great product and worth the extra cost.

At time of purchase (6/11/12), there were 3 reviews, all 5*. On date I installed it, a 2* review was posted saying the Nomex gasket failed at 700+ deg. F. I had an installation issue surface, and contacted High-Que to seek their input. This Company offers excellent customer service. Technical support fully resolved the technical issue to my complete satisfaction. We also spoke about the review saying the gasket fails at 700+ deg. F.First, I was advised they had a few gaskets fail at extreme high heats . . . high 700's to 1,000+ deg. F. In addition, there may be other contributing factors such as someone propping open the BGE top with something metal (like tongs) which transfers direct high heat to the gasket, resting an extremely hot pan/pot on the gasket, or long periods of time at extreme high heat as the person got distracted by something such as drinking a few beers to many. Importantly, they're not aware of any premature failures at temperatures of 650 deg. F or below. I came away with a view that this gasket is considerably more heat resistant and durable than the factory felt gasket but not fail proof under certain conditions. If you're thinking of installing this gasket so you can grill at 750+ deg. F temps for 15 minute cooks or more, and you're expecting this to be a long-term gasket solution, you're probably going to be disappointed.Concerning the installation of this gasket. It is simple to install but a messy, time consuming job. Most of the time is spent cleaning the old felt remnants and adhesive from both rims. The video shows a dirty rim being scraped and then it morphs to a very clean surface just before acetone is applied (I don't think the rim got that clean using a scraper). I didn't think the acetone removed the old adhesive very well. I tried a little 3M General Purpose Adhesive Cleaner (#08984) on a scrap piece, and it seemed far easier to remove the old adhesive as compared to using acetone. However, I decided to follow directions since unsure if the 3M product might leave an invisible residue that might interfere with the adhesive of the new gasket (suspect it would not especially if wiped down afterward with acetone). One tip not made clear in the directions or video is to either have someone tilt the top or have something to prop open the top to prevent it from slamming shut when starting to apply the gasket at the rear Spring Assisted Band. If not done, the tiny space at the rear mechanism makes it difficult to slide in the gasket (or run risk of it getting bound up or stuck incorrectly). Also having a pencil handy when over laying the gasket where the seams meet allows a pencil mark to be made on each side of the gasket creating an imaginary line for using sharp scissors to make the angle cut so the seams perfectly align with one another.
