Default Loose top caps.

Hi,
Does anyone know of an adhesive suitably for re-fitting tube anode top caps? I've tried superglue( unsuccesfully) Preferably something available in the UK?

Regards,

David.

I've heard the expansion rate of the glue used for re-fitting the cap might be different from that of the glass, so eventually it'd crack around the new fixing. It's not a first hand experience, so that's for reference only. And please correct me if I'm wrong.

How about just remove the cap and use an alligator clip?

You need a high temp cement made specifically for glass-to-metal seals. Sauereisen is the gold-standard brand.

I've used silicone RTV. High temperature rating, sticks to glass...
