Value Adhesives, Glues & Cements

Overview

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.
