Black Electrical Tape, is it reef safe?

[thebanker]

I realized that I've recently expanded the OD of a couple fittings using regular black electrical tape. Is there anything in there I should worry about?

e.g. Don't use that tape you idiot, it is filled with copper!!

Looking at the MSDS sheet provided below, I don't see anything myself that would pose a problem.

This is a 3M black eletrical tape MSDS:

They do have some unknowns in the MSDS that are Trade Secrets. :lol:

Thanks Cliff, very helpful as usual.

Anyone else used black electrical tape long-term in any reef application underwater?

I've never used it on my tank, but I can say that electrical tape and water don't mix well IME. Seems like it always looses it's sticky pretty fast. But for sizing up a fitting, the sticky may not be whats holding it.

FWIW, if the electrical tape doesn't work well, you may consider replacing it with silicone tape which is waterproof.

A few years back, I used electrical tape as a gerry rig to close a hole on the output of a pump for a GFO reactor. Considering there is pressure, it lasted a few months. I later did as Highlander suggested and replacing it with silicone tape. That lasted longer. Finally got around to replacing the pump. No ill effects.

I've used a little electrical tape exposed to the water , here and there over the years without any noticeable ill effects.

Breeders use it to cover the orange light on their heaters but that is not reef specific.

Thanks, this is what I was looking for. With a recent die-off in coral I'm making sure no stone is unturned.
