  • soldering paste vs tinning flux

    i had to repair a copper water line for a friend and forgot my soldering paste. i usually use oatey no.5 lead free soldering paste. in a pinch, my friend had oatey no. 95 tinning flux. i noticed that once the solder had run, it seemed to "set up" much faster and wiped better than when i have used no.5 paste flux. has anyone else experienced this? i've checked the oatey web site, but i'm interested in what the pros here use? any info would be appreciated

    Doesn't tinning flux have small amounts of solder in it?

        Been using Oatey #95 tinning flux for years. Just like it all around and works well.

        Used #5 in new construction for years and hated how the product would turn to almost liquid consistency in the heat, rock hard in the cold. The tinning flux spreads better and is a great deal more forgiving.

          is this water soulable flux?

          water soulable flux is all we can use on potable water lines.

          everflux is our flux of choice

              Not solder but silver. I've tried this but don't care for the silverish particles it leaves on the pipe. I prefer Nokorrode which does the same thing but doesn't have any negative effects. #95 won't turn pipe green which is a plus.

                  Re: soldering paste vs tinning flux

                  so, is the consensus that the tinning flux is superior to the soldering paste?

                        Re: soldering paste vs tinning flux

                        It all depends on the plumber, some use way to much paste so when tinning flux is used it looks like a unprofessional job, silver all over the pipe and fittings. You also have to be careful not to miss a joint when soldering as it will look as if it is soldered. I like the #5 paste because I can see the flow of solder around the joint.

                          That product is terrific for me.

                          I don't use it but all the DIY'rs around here do, they don't understand that there's a very small small window of temperature whereby it either takes solder or burns up black.


                          That has me coming to the rescue with my tinning flux method and making it look almost embarrassing how easily I correct the problem.

                          Tinning flux as mentioned can look terrible if used and abused. I use such a minimal amount that a small tin lasts beyond a safe zone to which the life of the product is questionable. Like any flux, it can separate in its container.

                          Here's an image of soldering done with tinning flux:

                              hawk, do you use a t-drill on these manifolds?




                              i should pack a big suitcase for the roundup and "hawk" some of my extra tools

                              i have an excess of t-drills and looks like you can use a nice one

                              maybe i'll take a photo of some to have a show and tell, with a buy it now for the roundup
