Harris 15620F1 Silver Solder 15 Percent 1 Lb Tube

Product Description

The HARRIS 15620F1 / 28 STICKS PER TUBE=1 LB. is a 15 percent silver brazing alloy sold in a tube of 28 sticks weighing 1 pound. This silver solder is formulated for joining copper, brass, and steel in refrigeration, HVAC, and plumbing systems. The 15 percent silver content provides strong, leak-resistant joints at working temperatures suitable for copper-to-copper and copper-to-brass connections. Licensed HVAC technicians and plumbers use this alloy when brazing refrigerant lines, water supply lines, and heat exchanger components that require a reliable, pressure-bearing joint.

This silver brazing alloy is suited for residential and light commercial HVAC and refrigeration work, including the joining of ACR copper tubing, service valve connections, and plumbing fittings. It is also used in general plumbing applications where a higher-strength joint than soft solder is required. The 28-stick tube format provides a convenient, job-site-ready quantity for service technicians working on routine repairs and installations.

Key Features

• 15 percent silver alloy content for strong, leak-resistant brazed joints
• 28 sticks per tube, net weight 1 pound for easy quantity tracking
• Compatible with copper, brass, and steel base metals
• Suitable for refrigeration line sets, plumbing connections, and heat exchanger joints
• Produces a free-flowing, ductile joint appropriate for pressure-bearing systems

Compatibility

Designed for brazing copper, brass, and steel assemblies in HVAC, refrigeration, and plumbing applications where a 15 percent silver alloy filler metal is specified.

Installation Notes

Silver brazing is typically performed by licensed HVAC technicians or plumbers in accordance with applicable mechanical codes. Purge refrigerant lines with dry nitrogen when brazing to prevent internal oxidation scale. Always use an appropriate flux for the base metals being joined, and allow the joint to cool naturally before quenching. Follow all applicable safety guidelines for torch use and ventilation when working in confined spaces.
