Do you mean these?

Yes. And what temperature rating. I see 1200*, 1800*. Wouldn’t 1200 be enough, or not.

I have the ones rated for
1200* degrees. They work
fine.

 

[What’s up dock]

The diameter needed would depend on what plug end you have. Measure yours, and get the next size larger. If don't have calipers to measure this, stop working on anything, and get some! They start at 8 bucks on amazon.

Good shot of them here.
They're the ones that are
7.50 inches long, rated @
1200 deg. They work very
well.
