$3,145.50/25lb tubeWhen you are running linesets all day or fabricating copper manifolds in the shop, you need a brazing rod that flows well, fills gaps, and doesn't break the bank. The Sil-Fos 5% Silver Brazing Rod is the industry workhorse for a reason. It gives you that extra bit of confidence compared to standard 0% rods, thanks to the 5% silver content which makes the rod more ductile and the finished joint tougher against vibration. If you are working on air conditioning coils, evaporator connections, or general refrigeration piping, this is the rod you want in your truck.
One of the biggest advantages of Sil-Fos 5 is its "sluggish" flow. Unlike high-silver alloys that turn to liquid instantly, Sil-Fos 5 has a wide melting range. This means it stays like peanut butter for a moment before it sets, allowing you to build up a cap or fill a joint that isn't fit up perfectly tight. It’s forgiving, which is exactly what you need when you're brazing in an awkward position upside down in a ceiling grid.
This 25lb tube is designed for the serious contractor or fabrication shop. Buying in bulk ensures you aren't running to the supply house every other day, and the 1.6mm (1/16") diameter gives you precise control over the puddle without dumping too much heat into sensitive components. Remember, if you are brazing copper to copper, you can leave the flux in the van—this rod fluxes itself. Just clean the copper, heat it up, and flow it in. For brass fittings, grab your flux pot, and you are good to go.
