- Braze copper tubing with ease and obtain consistent, leak-free, and tight sealings. 15% Brazing Rings are designed with a calculated alloy volume for use with standard size copper tube from 1/4 inch to 1-1/8 inch.
- 15% Brazing rings have the same chemical composition and comply with the same AWS A5.8, BCuP-5 standards used for brazing copper tubular components for HVAC/R installation applications. The preformed ring presentation minimizes waste and is easy to use repeatedly.
- Silver Phos-Copper 15% is a copper-rich, filler metal that is self-fluxing on copper by virtue of its phosphorus content. The self-fluxing property of this filler metals is effective on copper only. With copper-based alloys, such as brass or bronze, the joints should be fluxed.
- Available Ring Diameters: 1/4", 3/8â€Â, 1/2", 5/8â€Â, 3/4", 7/8â€Â, 1-1/8â€Â(Carefully check the table with rings sizes and specifications) – Available Package quantities: 10-Pack and 25-Pack – Select your option from the Size and Package Quantity dropdown menus.
- ***Images are for reference only: size and quantity of rings will change based on the selection made on the Size and Package Quantity dropdown menus***

How to braze with 15% Brazing Rings:
- Using abrasive paper or brush, clean all the surface of contact to be brazed, in both the tube and the coupling, make sure there is no contaminants residue or debris.
- Insert the brazing ring into the coupling and then insert the tube and make sure it makes contact with the ring. Couplings and fitting with a stop are preferable.
- Heat the tube and fitting uniformly. Oxy/Acetylene, Air/Acetylene, and Propane or MAPP torches can be used. With copper tubes no flux is needed, for other metal like brass, you need to apply flux.
- Once the ring melts, the silver alloy will flow out by capillary action and will be visible at the top of the joint leaving a uniform fillet around.
