What do you use for sealing threaded fittings?

Will this stuff work on PVC to ABS? I was told it will not bond, that was why mine leaked. Was told to use the green stuff for ABS to PVC called transition cement, PVC pipe into ABS bulkhead.

I used it on my water change station 2 years now. fingers crossed

can you explain why not? the video I saw (wish I could find it) was from an experienced reefer who uses it for all threaded fittings and said you can disassemble it and just brush away the chunks and re-use if needed. I have thought about it and can't see a reason why it shouldn't work

I may be wrong, as long as it it reef safe it should work okay. I have never tried it so I should not have said that. Sorry, just something I would not try unless you know for sure.

This is what I was told to use. Glad you have no trouble with yours, it may have been the way I installed mine that caused the leak.

I use silicone. I also use all of these in situations. Never used the paste for aquarium use. Only times I would not use silicone is if you have a joint that has stress on it, or a spot that gets water hammer effect.

Wow. really surprised to see all the Teflon Tape responses.

for some reason I can't find the video I watched before but I did find this thread with many recommending silicone

This is probably what you were looking for, guy has more experience than many on this forum combined.

yes! that was it! :D However, just think how many ABS bulkheads are out there in the world and not leaking.

I've been using this ever since giving up on tape and been very happy with it...
