Can this product be used with lead (50/50, 95/5) solder ?

Asked by: Barron
Water Soluble flux should not be used with 50/50 solder applications. 50/50 solder is only approved on DWV applications.

I was starting to wonder if I had forgot how to solder after wasting an hour of time and a half dozen or so fittings. I went back and bought some plain flux that was not water-soluble and that worked great. I do not see how anyone uses this

I was questioning my sanity with 20+ years of plumbing experience and could not get this flux to work. Numerous destroyed fittings, straight up frustration. Walked down to fathers house and borrowed a container of regular flux....yep worked as it should every time. I do not understand why this is still being sold! Waste of time and money.

Rated 1 out of 5 by from Terrible flux. Do NOT buy! This flux resembles vanilla pudding --- yellowish, very soft and somewhat runny. When I used this flux, the solder wouldn't run into the fixture. It just "blobbed" up. Ruined several fixtures, as I didn't want to reuse them with other flux. Returned it and bought some dark acid flux, which worked perfectly, right away, every time. I even asked a plumber at Home Depot if I had been using it correctly. He said that I had, but that it's worthless and he has had many complaints about it. Do NOT buy this flux. I don't know why they even sell it. I wish I could give it ZERO stars!

Rated 4 out of 5 by from works for me I tried some sweating copper fitting to 1/2" pipe at the bench with some no name flux that I had from somewhere. solder pretty much all went on the floor. visited HDepot and talked to a guy there that has given me good advice in the past and he recommended this red label flux. also some suggestions on sweating. clean the surfaces well; coat fully with flux; assemble and do the soldering soon; heat the fitting about midpoint of the enclosed pipe (not on the edge where the solder is to go); if fitting is horizontal heat the bottom half; when hot enough apply the solder at the top; clean the pipe with water wet rag after it cools. This flux worked well for me. A trick that I came across worked pretty well. Oatey also sells a tinning flux; it's dark gray and contains some finely dispersed metal. I put a dab of that at the spot that I intend to start the solder flow; the suspended gray metal spreads and tins the copper at about the temperature that solder melts. this gives you a temperature gauge at the spot that you melt the solder. I believe that the tinning flux is primarily intended to tin wire but this temperature sensor trick works pretty well. and for four bucks... I gave it four stars because I don't have enough experience to say that there isn't something better out there

Rated 1 out of 5 by from don't use this flux Flux would not draw solder into joint. Heated fitting all the way to red hot with testing of solder all along the heating process at different intervals. Just would not pull the solder in. Just have a nice pile of solder on the basement floor.

Rated 1 out of 5 by from near worthless The purpose of flux is to make good sweat fittings easy. In direct heat turns it to a black ash making a quality fit nearly impossible.
