Value Collection CWSN97CU3RA.031 Lead-free Solder 1 Lb

Product Description

The VALUE COLLECTION CWSN97CU3RA.031 is a lead-free solder wire formulated with a 97% tin and 3% copper alloy, designed for plumbing, HVAC, and light electrical applications where lead-free compliance is required. Supplied in a 1-pound spool at 21 gauge, this solder meets common lead-free requirements for potable water systems and other installations where leaded solders are restricted or prohibited. The tin-copper alloy provides reliable flow characteristics and solid joint formation on copper pipe and fittings. Licensed plumbers, HVAC technicians, and skilled tradespeople working on copper tubing systems will find this a straightforward drop-in for lead-free soldering work.

This solder is suited for residential and light commercial copper pipe soldering, including water supply lines, HVAC refrigerant-adjacent copper work, and other applications where a lead-free alloy is specified by code or project requirement. The 21-gauge wire diameter is appropriate for standard sweat-soldering of copper fittings. At 1 pound per spool, the quantity is practical for service calls, repair work, or small installation jobs. No specific brand or model compatibility restrictions apply beyond the material and gauge requirements of the application.

Key Features

• Lead-free alloy meets code requirements for potable water and restricted-use applications
• 97% tin and 3% copper formulation provides strong, reliable solder joints on copper
• 21-gauge wire diameter suited for standard sweat-soldering of copper pipe and fittings
• 1-pound spool is practical for service, repair, and small installation jobs
• Compact spool dimensions make it easy to store in a service vehicle or tool bag

Compatibility

Designed as a lead-free solder for use on copper pipe and fittings in plumbing, HVAC, and related trade applications where a 97/3 tin-copper alloy at 21 gauge is specified.

Installation Notes

Sweat-soldering with this material should be performed by a licensed plumber or qualified tradesperson following applicable local plumbing codes, including IPC and IFGC guidelines where relevant. Shut off and depressurize the water or fluid system before beginning any soldering work, and ensure the pipe and fitting surfaces are clean and dry prior to applying flux and solder. Use appropriate personal protective equipment including eye protection when working with open flame and molten solder. Allow completed joints to cool fully before restoring system pressure.
