Harris RF15375 Stay-silv 15 Brazing Ring 3/8 in 25 Pack

Product Description

The HARRIS RF15375 is a Stay-Silv 15 percent silver brazing joint ring designed for consistent, controlled braze joints in copper and copper-alloy tubing applications. Sized at 3/8 inches, this preformed ring seats directly in the joint before heating, delivering a measured alloy dose without hand-feeding filler rod. The result is a repeatable braze with predictable flow and minimal waste. Each package contains 25 rings. HVAC technicians, plumbers, and refrigeration mechanics rely on preformed rings when working in tight access areas or when joint consistency is critical to system integrity.

The RF15375 is suited for residential and light commercial HVAC and refrigeration work, as well as plumbing and hydronic piping where 3/8-inch copper connections are common. Preformed rings are especially practical on production-style installs or service calls where multiple joints of the same diameter need to be brazed quickly and uniformly. The Stay-Silv 15 alloy flows well with a standard air-acetylene or oxy-acetylene torch setup and is compatible with flux-coated or separately fluxed joint preparations.

Key Features

• Stay-Silv 15 percent silver alloy formulation provides strong, leak-resistant braze joints
• Preformed 3/8-inch ring eliminates hand-feeding and reduces alloy waste
• Consistent alloy dose per joint supports repeatable results across multiple connections
• Suited for tight-access applications where rod feeding is difficult
• 25-ring pack supports multi-joint service calls or small installation runs

Compatibility

Designed as an OEM-style preformed brazing ring for use on 3/8-inch copper and copper-alloy tubing joints in HVAC, refrigeration, and plumbing applications.

Installation Notes

Installation should be performed by a licensed HVAC technician, refrigeration mechanic, or journeyman plumber familiar with silver-alloy brazing procedures. Recover or isolate any refrigerant and shut off all gas or fluid supply before opening the system. Apply appropriate flux per the alloy manufacturer guidance and use an air-acetylene or oxy-acetylene torch sized for the joint diameter. Allow the joint to cool naturally before pressurizing and leak-checking the system.
