Super Glue or PVC cement?

[Bryan47]

Hey guys!
So this is cheap pump from "barber weight" the cheap hardware store and I tried unscrewing a fitting someone must have glue in and it cracked, I'm wondering if PVC cement will work on this? It's nothing critical I just use it to transfer water so I'm always around should it fail.
So what do you think PVC cement or superglue?

thank you!!!

I would try super glue. Not sure PVC cement can penetrate that kind of plastic.

What's the strongest I can buy? Gorilla glue?

 

[TheEngineer]

Gorilla glue is strong, but I don't know if it is reef safe.

Found the manual somehow lol and it says it's encapsulated in "epoxy resin" so maybe I should use plastic epoxy?

That epoxy is to keep the electrical components from coming into contact with water. You could use an epoxy, but I'd be worried about it bleeding into the cavity.

Make sure you rough up the plastic a little to help the bond. Not to much as to mis-shape it just lightly with some higher grit sandpaper.
2 part epoxy is good and reef safe as far as I know. They Do make a plastic "super glue" that works really well but idk if it's reef safe?

Chances are that pump body is made of ABS, I would try ABS cement. Super glue is not going to work.

I use gorilla super glue gel for my corals and have never had problems.

I'll bet it is abs plastic. Most fittings like thst are.
