Forney Industries 48571 Super Sil-flo Brazing Rod

Product Description

The Forney Industries 48571 is a Super Sil-Flo brazing rod used for joining copper, brass, and bronze in refrigeration, HVAC, and plumbing applications. Each unit weighs approximately 0.5 pounds, and the packaged assembly ships at 2.48 pounds covering a package quantity of 4 units. HVAC technicians and plumbers rely on this type of silver-bearing brazing alloy when making leak-free joints on refrigerant lines and water supply connections where a lower-temperature flow is an advantage over hard silver solder.

Super Sil-Flo rods are commonly used in residential and light commercial HVAC service work, particularly for copper-to-copper and copper-to-brass refrigerant line connections. They are also used in plumbing for joining copper tubing where a free-flowing alloy that wets joints quickly is preferred. This rod is sold individually as a single unit of measure.

Key Features

• Super Sil-Flo alloy formulation designed for free-flowing, low-void brazed joints
• 0.5 pound per rod — easy to stage and portion on the job
• Compatible with standard torch brazing setups using air-acetylene or oxy-acetylene
• Suitable for copper, brass, and bronze base metals
• Packaged quantity of 4 rods available per order

Compatibility

Designed as an OEM-style consumable brazing rod for use on copper, brass, and bronze assemblies typical in HVAC refrigerant piping and plumbing systems.

Installation Notes

Brazing work on refrigerant lines must be performed by an EPA Section 608 certified technician, and the refrigerant system must be properly recovered before any open-flame work begins. Purge refrigerant lines with dry nitrogen during the brazing process to prevent internal oxidation scaling. Allow all joints to cool completely before pressurizing and leak-checking the system. Follow applicable local mechanical codes and ASHRAE guidelines for brazing procedures on refrigerant-containing components.
