Pipe joint compound vs PTFE Tape
Any marine plumbing experts here?
I'm in the middle of a small plumbing job involving the salt water cooling loop for the air conditioning units. I'm planning to use PTFE (teflon) tape on the pipe threads. Are there any issues with that as opposed to using joint compound goop that anyone knows of? |

I'm no expert on plumbing, but I can't see any reason why the tape shouldn't work, Wayne. That stuff gets used on PCV on lots more than mere salt condition. If no one else can give you a comprehensive reply, I'll be talking to my friend who is a 26 year veteran licensed plumber in the morning and get an answer for you. |

Pipe joint compound vs PTFE Tape
I recently had to redo the piping coming out of my water heater and there
were several joints in the iron pipe that I couldn't get to stop leaking when using the teflon tape. I got some of the dope with teflon in in and that finally stopped the leaks. If you look at what happens to the tape when you tighten the joint you can see that it gets cut to shreads. Lubricate, maybe. Seal, no. wrote in message ...

If you use pipe dope, be sure it is OK for plastic (assuming this is PVC). I have some teflon laced pipe dope that works great on plastic. In both cases, this is really a lubricant more than a sealant. It is the thread to thread connection that does the sealing. The dope/tape is just there to prevent galling. |
