Or Araldite if you thoroughly degrease the joint first?

I wouldn't use Araldite on a joint exposed to heat cycling. A few years ago
I used it to re-affix the plastic nozzles in several hot water taps around
the house. Within a few months the Araldite had become brittle and was
coming away in chunks.
Cheers,
