Safe thread sealant?

[Jake95]

Hey guys, just wondering if this is safe? http://www.lowes.com/pd_23502-138-3...ing_4294935907__s?Ntt=oatey&page=2&facetInfo=

Play it safe, use telfon tape.

It says it's non-toxic, but I'd have to agree with Paul. You shouldn't need anything more than teflon tape for your aquarium plumbing... and that's proven to be safe.

I have teflon tape on them now, but ive heard teflon tape really doesnt last when sealing plastic threads-to- plastic threads.

Teflon tape works great for plas to plas. Use 3-4 wraps, no less, no more. Too few might leak, too much can crack the fitting

For really poorly cast threads I've used a bead of silicone around the male fitting before screwing them together. But you need to let the joint cure for 24-48 hours before getting it wet.

Sequence pump people say not to use tape, it won't work to connect to their pumps. Remember these products need to be safe for drinking water. They are not toxic. I originally used Hercules Sta-Tuf, but I had trouble getting a leak-proof seal. Now I use Hercules Pro-Dope, which works much better and doesn't require that you slop it on.
