Harris 331861 Tin Antimony Solid Core Solder 3/32 in 1 Lb

Product Description

The HARRIS 331861 is a 95/5 tin-antimony solid core solder supplied on a 1 lb spool, with 25 spools per box totaling 25 lbs. Formulated as a lead-free alloy, the 95/5 composition delivers a strong, reliable bond suited for pressure-bearing plumbing and refrigeration applications. The 3/32 inch wire diameter feeds consistently through standard solder tools, giving technicians good control on both small-diameter fittings and larger joint assemblies. Installed by licensed plumbers and refrigeration technicians, this solder meets the demand for a dependable, code-conscious joining material across a wide range of service work.

This solder is formulated for use in potable water plumbing, refrigeration lines, cooling lines, and general soldering applications. The 95/5 tin-antimony alloy is appropriate for both residential and light commercial installs where a lead-free solid core solder is required. Sold in a 25 lb box of 25 individual 1 lb spools, it is well suited for shop stocking or field supply for crews running multiple jobs. The solid core construction requires flux to be applied separately, which is standard practice in plumbing and refrigeration work.

Key Features

• 95/5 tin-antimony alloy — lead-free formulation for potable water and refrigeration compliance
• 3/32 inch wire diameter for consistent feed and joint control
• Solid core construction — compatible with paste or liquid flux applied separately
• 1 lb spool format with 25 spools per box for easy inventory management
• Suitable for plumbing, potable water lines, refrigeration, and cooling line applications

Compatibility

Designed for use in potable water plumbing systems, refrigeration lines, and cooling lines where a lead-free 95/5 tin-antimony solid core solder is required.

Installation Notes

Installation should be performed by a licensed plumber or refrigeration technician in accordance with applicable local plumbing codes and the International Plumbing Code (IPC). Shut off the water supply or recover refrigerant from the system before beginning any soldering work. Clean and flux all joint surfaces prior to applying heat to ensure proper solder flow and adhesion. Do not apply solder to wet or pressurized lines.
