Harris SSWF1 Stay Silv Brazing Flux, 1 lb. Jar, White

Very effective, easy to use, works great. Excellent flux.

Good price on a good product.Don

I have used this product for decades I have been sharpening repair saws and tools for 45 years + works great when I bought it through Amazon it was light I bought it through Walmart and it weighed correct

I couldn’t get the solder to stick to the stainless with this stuff. Maybe it’s me.Update: This is brazing flux a propane torch is not hot enough.

Works great.

If you are going to work with silver bearing solder this is the flux you need! This is a high temp paste that is perfect for silver soldering refrigerant lines.

I recently took a class demonstrating a particular technique for making prong settings. One of the required items for the class pack was this black flux. I've used several types of flux in the last 20+ years, but had never even heard of this.The first jar opened up inside the packaging and there was black gunk ALL over...so I sent that back for a new jar.We used this flux in the class and it is amazing. First of all, when you paint on a dot of this onto a tiny prong, you can actually SEE it, so you know exactly where it is and whether you got it on the join. It does turn clear once it approaches temperature, so you will see your solder flow. And you can conduct several soldering operations in a row without having to pickle between each step. For production work, that is vital.Prior to this, I usually have used the spray fluxes (like Prips, etc.). They are great, but they coat your soldering board or block with gunk and frankly they don't last as long as they should because of it. With this stuff, you can just use a tiny bit right on the join and not gunk up your expensive block.I highly recommend this flux.
