Harris 0 Phos-Copper Brazing Rod 3/32" x 20" (25lb Box)

Harris 0: The Standard for Copper Brazing

When you need a reliable, low-cost brazing rod for copper plumbing or HVAC lines, Harris 0 is the go-to choice for professionals. This 25lb box of 3/32" rods ensures you have plenty of material for big jobs without breaking the bank. Known for its fast-flow characteristics, Harris 0 (BCuP-2) melts and flows like water once it hits temperature, making it perfect for tight-fitting joints where deep penetration is key.

Why Choose Harris 0?

• No Flux Needed on Copper: Save time and mess. The phosphorus in the rod acts as a flux when you are brazing copper pipe to copper fittings.
• Economical: With 0% silver content, this is one of the most affordable brazing alloys available, perfect for standard plumbing and refrigeration loops where vibration is minimal.
• Clean Joints: Produces smooth, neat fillets that require minimal post-braze cleaning.

Best Practices

Because Harris 0 is very fluid, it works best on joints with tight gaps. If you have a loose fit-up, you might struggle to bridge the gap with this alloy (consider Harris 15 or a flux-coated bronze for gaps). Always clean your copper ends thoroughly before brazing to ensure the alloy wets out properly. Remember, if you are brazing onto brass valves or fittings, you must use a flux like Stay-Silv to get the rod to stick.

Safety and Storage

Keep your 25lb box in a dry place to prevent surface oxidation on the rods. Always braze in a well-ventilated area, as brazing fumes can be hazardous. This package contains 20-inch rods, which are a standard length for easy handling and feeding during the braze.
