Question Tinning Flux?

Both a Oatey video and an article in Family Handyman recommend using 'tinning flux' for sweat fittings.

I have Alpha Fry Plumbing Repair Flux Waterflow 2000 Paste Flux.
Is this a tinning flux, I see no mention of tin?

I'll be using this on a few 1/2" tees and elbows.

Thanks,
Baldwin

Baldwin,

Tinning means to apply solder to a fitting or object prior to assembly.
If using a soldering IRON you would clean the tip, apply flux, heat it up and then apply a coating of solder.
This is tinning.

You only need to clean your fittings, apply flux, assemble, (or assemble and apply flux as some do), heat and then apply solder.

Greg,

This must be some new stuff they've come up with.

The article in Family Handyman says this:

"We recommend tinning flux. It contains a bit of powdered metal alloy that is similar to solder. The alloy melts and coats the inside of the joint and helps ensure a solder joint that's completely filled and leakproof."

What will they think of next? This stuff I have must be a different animal so it's off to the store I guess.

Thanks,
Baldwin

Looking at the picture in the magazine they show a can of 'Oatey No. 95 Lead Free Tinning Flux.'

The goop is gray or dark green in color.

Hope I can find some.

I use tinning flux all the time. It is dark gray.


I bought it by accident once and like the way it applies (bonds) to the freshly sanded pipe when preparing a solder joint.


It does contain what you describe, but you still have to solder the joint.


I like the finished look the joint gives and the ease of use.


I am an exception on this though, not many plumbers use it.

I havn't tried the stuff but will look for it as I like trying all the different things that show up on suppliers shelves.
I usually wind up going back to the old standard but it's fun trying different things.

Dunbar mentioned 'ease of use'. That's for me!

Thanks guys,
