Does the Harris 95/5 Lead-Free Solid Wire Solder 3/32" 1 lb Spool - 331861 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.

What is the correct soldering technique for the Harris 95/5 Lead-Free Solid Wire Solder 3/32" 1 lb Spool - 331861?

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 95/5 Lead-Free Solid Wire Solder 3/32" 1 lb Spool - 331861 available in?

The Harris 95/5 Lead-Free Solid Wire Solder 3/32" 1 lb Spool - 331861 is available in 3/32 diameter. Wire solder diameter selection depends on the joint size: fine wire (.050–.062 in) suits electronics and tight plumbing fittings; medium wire (.093–.125 in) is the most versatile for general plumbing work; larger diameter wire suits large-bore fittings and faster deposition.

How should I store the Harris 95/5 Lead-Free Solid Wire Solder 3/32" 1 lb Spool - 331861?

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 95/5 Lead-Free Solid Wire Solder 3/32" 1 lb Spool - 331861 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.

95/5 Solder-Safe lead-free solid wire solder 3/32 in. x 1 lb. spool x 25 lb. per box

Overview

95/5 Solder-Safe lead-free solid wire tin-antimony solder solder has a low temperature with a narrow melting range. It is primarily used for copper plumbing tube but can be used for other general soldering applications. The rapid melting characteristics require close fitting connections as it is difficult to "bridge" or fill wide clearances. Manufactured per composition ASTM B32 Alloy Sb-5. This solder is NSF 372 certified and meets the requirements of the US Safe Drinking Water Act. Complies with the EU Reach & RoHS directive.

Features

Solid wire tin-antimony solder
Lead-free, low temperature solder
Narrow melting range
Requires close fitting connections
Used to solder copper plumbing and for general soldering applications
Silver/gray color as deposited
