Nicked a plastic central heating pipe with the grinder

I nicked a plastic central heating pipe with the grinder. I'm surprised its not leaking.
Quite deep, actually amazed its not leaking.
Is there something, a glue or epoxy I can coat round it that will make it good as new, something like a putty?

Depends how well you want to sleep! Any concerns and I'd cut it out and replace it with a new section.

Thanks for the reply.
The next day we discovered it was old heating system poly pipe not connected to anything.
