What is the correct soldering technique for the Harris Sterling®.118 in x 5 lb. spool x 25 lb. box Lead-Free Solder - 331898?

Soldering technique for copper plumbing: clean pipe and fitting surfaces with sandpaper or steel wool until bright, apply paste flux, assemble the joint, and heat the fitting (not the solder) with a torch until solder flows freely when touched to the joint. Remove heat as soon as the solder flows — overheating burns the flux and can cause a dry joint or oxidized solder. Allow to cool for 30 seconds before wiping and moving the assembly.

What diameter and quantity is the Harris Sterling®.118 in x 5 lb. spool x 25 lb. box Lead-Free Solder - 331898 available in?

Wire solder is sold in various diameters and spool weights. For residential plumbing, 1/8 in (3.2 mm) or 3/32 in (2.4 mm) wire on a 1 lb spool covers most common repairs. For production plumbing work, larger spools (5 lb, 25 lb) minimize changeover and reduce per-foot cost.

How should I store the Harris Sterling®.118 in x 5 lb. spool x 25 lb. box Lead-Free Solder - 331898?

Store solder in a cool, dry location away from moisture and chemical fumes. Lead-free solders containing silver (Sn-Ag, Sn-Ag-Cu) are more brittle than traditional tin-lead solders and should be handled with care to avoid cracking the wire on the spool. Flux-core solder should be stored away from extreme heat to prevent flux degradation inside the core.

Q: What is the Harris Sterling®.118 in x 5 lb. spool x 25 lb. box Lead-Free Solder - 331898 used for?

Lead-free solder is used for joining metal components at temperatures below 840°F (450°C) in plumbing, electronics, and light metal fabrication. Lead-free solders are required by NSF/ANSI 61 for potable water plumbing systems and are mandatory in many states — never use lead-containing solder on drinking water supply lines.

Q: Does the Harris Sterling®.118 in x 5 lb. spool x 25 lb. box Lead-Free Solder - 331898 require separate flux?

A separate flux must be applied to clean joint surfaces before soldering with wire or bar solder. Harris Bridgit Flux or a similar non-corrosive paste flux is recommended for plumbing copper joints. Apply flux to all contact surfaces, assemble the joint, then heat the base metal and touch solder to the joint — the solder flows by capillary action into the flux-wetted gap. Remove flux residue after the joint cools.
