Value Collection 1394440ACP31251 Acid Core Solder

Product Description

The VALUE COLLECTION 1394440ACP31251 is an acid core solder supplied in a 1-pound spool, formulated with an alloy composition and featuring a 66-series flux core at 11 gauge. Acid core solder is designed for soldering metals where an active flux is required to cut through oxidation and surface contamination, producing a strong mechanical and electrical bond. It is commonly used by plumbers, HVAC technicians, and sheet metal workers on copper pipe joints, metal fittings, and other ferrous and non-ferrous surfaces where aggressive flux action improves wetting and flow.

This solder is suited for residential and light commercial plumbing, HVAC sheet metal fabrication, and general metal joining applications. The acid flux core eliminates the need for a separate flux application in many soldering scenarios, streamlining the workflow on copper and metal assemblies. It is not intended for use on electronics or electrical connections, where a no-clean or rosin core solder is the appropriate choice.

Key Features

• Acid core flux integrated into the solder wire for active oxide removal during application
• 66-series core designation indicates flux core construction suitable for metal joining
• 11 gauge wire diameter for controlled feed and consistent deposition
• 1-pound spool provides a practical supply quantity for field or shop use
• Alloy composition supports strong, reliable bonds on copper and compatible metals

Compatibility

Designed as a general-purpose acid core solder for use on copper pipe, sheet metal, and compatible ferrous and non-ferrous metal assemblies in plumbing and HVAC applications. Not suitable for electronic or electrical soldering applications.

Installation Notes

Acid core solder is applied by licensed plumbers and HVAC sheet metal technicians using a soldering iron or torch appropriate to the joint size and metal type. Always ensure the work surface is clean and the flame or iron temperature is matched to the solder alloy to achieve proper flow. After soldering, residual acid flux must be thoroughly cleaned from the joint to prevent ongoing corrosion. Follow all applicable codes, including IFGC and IPC guidelines, for soldered joint applications in gas and plumbing systems.
