Soldering Flux Paste for All-Weather Use

La-Co 22104 is a water-soluble soldering flux supplied in a 4 oz plastic jar. The paste formulation meets ASTM B813, Mil Spec Mil-F-4995 Type II and NSF/ANSI 61-G standards. It is designed for joining copper, brass, galvanized iron, lead, zinc, tin, silver, nickel, mild steel, terne plate and malleable iron across a wide temperature range.

Suitable Metals and Compliance Needs

This flux suits plumbers, HVAC technicians and metalworkers who need a paste that cleans with water and satisfies the listed ASTM, military and NSF 61 certifications. Workers requiring a flux for stainless steel, aluminium or other alloys not named in the specifications should look at a different product.

Water-Soluble Paste Formulation

The single specification that decides fit is the water-soluble paste chemistry combined with the NSF/ANSI 61-G listing for potable-water systems. If a project demands a non-soluble, acid-based or non-certified flux, this jar will not meet the requirement.

Questions about this item

Which container size should I pick for occasional plumbing jobs?

The 4 oz plastic jar supplies enough water-soluble paste for many small copper or brass connections and stores easily between uses.

What does the all-weather working range mean when I am soldering on site?

The flux stays active across a wide temperature span so it will not freeze in cold weather or break down on hot pipe runs.

Which standards does this flux meet for potable-water systems?

It complies with ASTM B813, Mil-F-4995 Type II and NSF/ANSI 61-G, so it is approved for drinking-water piping.
