Highest heat resistant gasket for Primo XL Kamado?

[AJR]

Hi folks,

I completely melted* the gasket on my Primo Kamado the first time I cranked it up north of 850 degrees for pizza. I replaced with a "High-Que Gold Standard Nomex and Kevlar Gasket, Replacement for Primo Oval x-Large 400 Grill High-Heat 14.5' " ** gasket, but I can't find online how hot I can get it and I'm now gun shy about getting it too hot. Does anyone know how hot this gasket can take or if there's a better one where I won't have to worry about how hot I take the Primo?

Thanks!

* full disclosure I used a hair dryer on the air intake to force the fire as hot as possible...

I use the High-Que gaskets on both of my Kamado Joes. I’ve never had high heat hurt one of them. I have had some ceramic cracking issues at very high temps, especially if the temp rises quickly.

AJR the first time I over heated one I started it with a full load of lump and left all the vents wide open. I ran to my office and came back in about 45 minutes to find the temp gauge pegged out and loud cracking sounds coming from the dome of my cooker. I had started it to do a high temp clean out burn and never dreamed it would get that hot. The next time I took it to 950 F and cracked the lower half. Kamado Joe sent me a note asking that I not go over 700 F.

AJR I believe I can run at 800 F to clean mine out if I just get there slowly so that uneven heating doesn’t cause stress cracking.
