Product Description
How to braze with SÜA 15% Brazing Rings: 1.- 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. 2.- 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. 3.- 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. 4.- 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.
Product Information
- Braze copper tubing with ease and obtain consistent, leak-free, and tight sealings. SÜA 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.
- SÜA 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.
- SÜA 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-base alloys, such as brass or bronze, the joints should be fluxed.
- Available Ring Diameters: 1/4", 3/8”, 1/2", 5/8”, 3/4", 7/8”, 1-1/8”(Carefully check table with rings sizes and specifications) – Available Package quantities: 10-Pack and 25-Pack – Select your option from the size menu. ***Images are for reference only: size and quantity of rings will change based on the selction made on the Size Menu***
