The flexible pipe on my pond filter inlet has split.

I've got some replacement piping but i want to use some sealant to help connect it to the filter.

Can anyone reccomend a sealant that I can use outside that is safe for fish/potable water?
 
Fernox jointing compound is safe for potable water - would that work?

You mean seal it on or stop potential leak?
If its connection only I prefer physical personally so would use a jubliee clip.

Silicon is fine (for both if you want) you must just ensure you get pure silicon and not one with anything funky like anti fungal stuff in it.

Plenty of tropical fish channels on youtube list ones that are compliant.
Or an search on Amazon etc.
 
Basically you need naturally curing silicone with nothing in it, no biocides, no anti mould etc.

Personally based on the description of what you are doing, I wouldn’t bother.
