![]() My stand for my 45g cube is finally finished and I'll need to water test my tank for leaks.
There are may choices for bulk heads (wet + dry side) threaded & threaded, threaded & slip and slip & slip. My cube came with threaded & threaded. On the wet side, I wasn't able to tighten the 3/4" threaded tube into the bulkhead connector. However, I had no problems with the 1" threaded overflows. In fact, I had a couple of rubber O-rings which I installed in between the threaded piece and the bulkhead making it water tight. I'm worried that the threaded + threaded bulkheads will eventually develop a slow leak over time. I'm interested in everyone's opinion for the different types. Thank you! |

![]() Using teflon tape will allow the threads to screw together much easier and will in sure they seal.

![]() You shouldn't have to add any o-rings when dealing with pipe threads
This can lead to failures down the road The 2 best options for connections outside your tank are threaded or slip. This does not include union style connectors Threaded you use tape, or better is to use liquid teflon (thread sealant). Slip you glue. Nothing else is needed if it's done properly Maybe someone living close to you could come by and look over your stuff/give you some help tips etc |

![]() Hello
You always use Teflon tape for threaded connections. Titus

![]() Gregzz4,
Is this the liquid Teflon you're referring to? http://www.homedepot.ca/product/1-oz...-teflon/967137 |

![]() As a gasfitter I have some experience with threads, Teflon and dope (liquid thread sealer). One of the first things they teach you in pipe fitting is that Teflon and dope have nothing to do with sealing the pipe, or prevention of leaks. The threads on the pipe and in the fitting ensure the seal. Teflon and dope is used for ease of disassembly. It is a common misconception that Teflon and dope seal the pipe. A pipe, properly threaded, should have 11 threads. After tightening into a fitting there should be 4 threads left exposed.
Also, pipe dope (liquid sealant is an improper name) is made of Graphite dust suspended in a petroleum catalyst. The one in your link has added white colouring. In retrospect, I would recommend using only white plumbing Teflon on your threads, and proper tightening techniques. You should never have a leak after that. Personally I would use slip with glue and unions. Good luck... and where's the pics? |

![]() Well there ya go
That is the stuff I've used. It's messy to work with and gets everywhere I prefer to use tape myself on anything I need to take apart later but recommended liquid as it's simpler for a layman |

![]() I've used teflon tape for plumbing around the house with threads. Its pretty simple and easy to use.
I've used the paste before and its messy. Thanks for the info. I'll stick with the tape. Sent from my GT-P5113 using Tapatalk |
