Which sealant?

[monzer]

My van was in getting a bit of work done on the fridge. The guy hadn't secured the vent properly so it is somewhere between Edinburgh and Glasgow. He ordered a new one and I went to pick it up. Thing is it is the new version that dometic took out to make it a bit harder for people to pinch them so I need to replace the whole lot.

Can anyone recommend the best sealant to use for this job?

Sikaflex.... there are many versions but 512 will stick it in place and hold it and it will seal it from water...

Or, from screwfix powerflex 40 I think ... much cheeper and does the job..??
