Rubber sealing from cooker overn door

A high temperature silicone will do the trick but you must get the surfaces perfectly grease free to start with.

An example is part no 423-6938 from

Check first to see if your oven has little holes near the corners of the surround. CPC sell a universal oven gasket kit, which is based on little hooky things to hold the gasket at the 4 corners, no high temperature sealant required.

Had a similar thing on a (old) Creda Concept - the door seal had streched over the years, but looked as if it had come unstuck or lost rubber-bung-thingies. A new replacement from the spares shop was definitely shorter, but fitted beautifully. Now working fine. hth Neil

The trouble is, it's bright red. Any genuine silicone sealant should be OK at normal oven temperatures.
