Utilm 14-220 Soldering Flux Paste 1 Pound

Product Description

The UTILM 14-220 is a 1-pound paste-form soldering flux formulated for professional metal joining in plumbing, mechanical, and industrial settings. Its ammonium chloride base chemically cleans metal surfaces by removing oxides, promoting uniform solder wetting and consistent flow. The paste consistency holds position on vertical and overhead joints during setup. Licensed plumbers, pipefitters, and industrial maintenance technicians are the primary installers. At 1 pound net weight, the container size suits both job-site use and shop bench work.

The 14-220 is suited for residential and commercial plumbing systems, mechanical assemblies, and general industrial soldering applications. It performs across a wide range of base metals, including copper, brass, galvanized iron, mild steel, lead, zinc, nickel, and silver. The formulation is compliant with lead-free plumbing standards, making it appropriate for potable water supply line work where lead-free solder and compatible flux are required by code.

Key Features

• Ammonium chloride-based paste flux removes surface oxides for clean solder adhesion
• Compatible with copper, brass, galvanized iron, mild steel, lead, zinc, nickel, and silver
• Compliant with lead-free plumbing standards for potable water applications
• 1-pound container suitable for sustained job-site or bench use
• Paste consistency stays in place on joints prior to heating

Compatibility

Designed for use with a broad range of base metals including copper, brass, galvanized iron, mild steel, lead, zinc, nickel, and silver; suitable for plumbing, mechanical, and industrial soldering applications compliant with lead-free plumbing standards.

Installation Notes

Apply flux to clean, dry metal surfaces immediately before soldering. Plumbers and pipefitters should shut off and depressurize any supply lines and drain standing water from the pipe section before work begins, per applicable IPC and local plumbing code requirements. Use only the amount of flux needed to coat the joint area — excess flux residue should be wiped away after soldering is complete to prevent long-term corrosion. Wear appropriate PPE including eye protection and gloves when handling flux compounds.
