Broken pump: Is Teflon tape safe to come in direct contact with water?

So my pump on my nanocube broke a few minutes ago and I've got it narrowed down to this magnetic tube connected to the propeller by plastic. The plastic broke, so the magnetic tube just spins and the propeller doesn't.

It's nearly 6:00 on Sunday and there's no way I can get to a pet store in time to get aquarium safe glue. I have to leave town tomorrow morning, and probably won't have time to get it.

That being said, I've got some tank-safe epoxy that I've tried to stick on there to glue it back together...and I wanted to try to teflon tape the area to help hold until I can buy a new pump when I get back in a week. But this means that the teflon tape will come in direct contact with the water.

Is this safe? Or does anyone have any other ideas for me? Thanks.

IMO as Teflon tape is used in all plumbing, I would think it should be fine for a temporary repair.

Not one shred of evidence supports the notion that life is serious.

Super glue gel is safe to use, if that will help.

You can use teflon tape, but I'm not sure it'll work. Teflon tape really only sticks to itself. Superglue or epoxy would be my choice.

Teflon tape is safe for use but as BigJim and ccCapt stated super glue gel or epoxy would be a better solution
