OVERVIEW

Reliable Brazing for HVAC & Refrigeration Pros

When you are out in the field fixing an AC unit or installing refrigeration lines, you need a brazing rod that works as hard as you do. The Harris Stay-Silv 15 is the legendary "15% silver" rod that pros trust for the toughest jobs. Why? Because it handles vibration better than standard rods and fills gaps like a champ. If your pipe fit-up isn't perfect—and let's be honest, in the real world, it rarely is—this rod's thick, pasty melting range helps you cap off the joint without dripping alloy everywhere.

Why Choose 15% Silver?
The extra silver in these rods gives your joints ductility. That means they can flex slightly under the constant vibration of a compressor without cracking. It's cheap insurance against callbacks and leaks. Plus, if you are brazing copper to copper, you don't even need flux—just heat it up and flow it in. For copper to brass valves or fittings, just add a little Stay-Silv flux and you are good to go.

Convenient Packaging
This pack comes with 24 sticks in a durable tube, so you can throw it in your truck or tool bag without worrying about snapping rods or getting them contaminated. At 2.5mm thick, these rods carry enough heat to flow smoothly but give you the control you need for precision work. Upgrade your brazing game with the industry standard for high-quality, leak-free joints.

FAQ

For copper-to-copper joints, Stay-Silv 15 is self-fluxing due to its phosphorus content, so no external flux is needed. However, if you are brazing copper to brass or bronze, you must use a flux like Stay-Silv White or Black flux.

No. Phosphorus-bearing alloys like Stay-Silv 15 should never be used on ferrous metals (steel, iron) or nickel alloys. The phosphorus reacts with iron to form brittle phosphides that will cause the joint to fail.

Stay-Silv 15 contains 15% silver compared to 5% in Stay-Silv 5. The higher silver content provides greater ductility (flexibility) and better impact resistance, making it superior for joints subject to vibration, such as near compressors.

This product meets the AWS A5.8 classification for BCuP-5.

This specific package contains 24 individual brazing rods.

Stay-Silv 15 has a solidus temperature of 1190°F (643°C) and a liquidus temperature of 1480°F (804°C). This wide range allows for bridging gaps in poor fit-ups.

Yes, Stay-Silv 15 is cadmium-free and generally safe for potable water systems, but always check local plumbing codes as requirements can vary.

These rods are 2.5mm in diameter, which is approximately equivalent to 3/32 inch.
