Heat Gasket Material

Hi All,
I have found I have had some difficulties regulating the temperature of my kettle BBQ. It has an attachment on the bottom that catches the ash in a removable container. The ash trap has vents to allow heat regulation.
The bracket for this ash trap is anything but airtight so the vents on the trap can be closed or open with no difference to the temperature of the kettle.
I have plugged some of the gaps in the bracket (cut outs to allow the trap to slide in and out) but where the bracket attaches to the kettle is another unintended vent.
I need to make a gasket of some form where the bracket meets the bottom of the kettle.
The easiest would be to use some hi-temp RTV sealant such as the J-B Weld one but I am not sure if it is suitable - it is rated to about 350°C.
What other gasket materials would be suitable? Is there a hi-temp sheet gasket available from auto stores these days? If so, which would be the one to get?

Would muffler putty (for exhaust joints) be an option?
Probably best to read the instructions/contents first. Then give it a good burn before trying to cook any food.

Maybe - I am not sure it would get hot enough to set the putty.

Here you go Rabbz

I'm thinking the ropes and silicon sealant combination will work to do what you need.

Yep, was going to suggest something like that but thought better of it.
I even saved a few sets of the racing brake pads, in the way back, as they were the last semi-metallic asbestos pads available.
They work damn well and last forever, unlike today’s pads.
Off course I was always cautious when working on the brake system with these pads.

Thanks Gee Nome. I might swing past the heating joint and grab some of the rope used to seal combustion stove doors.

It's James Hardie (I used to work at their Rosehill factory - after the clean up). James Hardy was a winemaker.

So the moral of this story is to not confuse brown asbestos with red wine....
Presumably this could only take place after a significant amount of alcohol had already been consumed.
Sounds like a great job you had Rabbitz.

At the time it was essentially just an office and warehouse - the asbestos had been buried and capped.
Some of the blokes who worked there in the bad old days told yarns about having 'snowball' fights with snowballs made of loose asbestos fibres.

Reminds me of the Engineering building at my Uni. Pens stuck in the asbestos sprayed. ceilings in the lecture rooms.
Mind you everything was asbestos when I grew up. My grandparents last house was sheeted with it everywhere: roof, gutters, and who knows what else.

Rabz, I got a tube of stuff, like grey coloured silicon sealant, for when I sealed the glass in the door of the fire box on Black Betty, I will dig it out tomorrow arvo and let you know what it is. Had some good fires in the box, temp got to over 400f in the smoke chamber, so would have been more in the fire box, it still as good as when I put it in.

Hey Camel,
Did you ever find the name of this sealant?
