The OATEY COMPANY 10619 is a lead-free, non-acid soldering flux paste designed for copper pipe and fitting connections in plumbing applications. Sold under the Hercules brand, this Climate Smooth formula is brushable across extreme temperature ranges and performs consistently in virtually all climate conditions throughout the year. The paste promotes faster, more uniform solder spread within the joint, reducing voids and improving connection integrity. The container ships with a built-in screw cap and brush applicator for direct, controlled application. Each unit weighs 0.5 pounds and is sold individually.
This soldering paste is suited for residential and commercial plumbing installations and service work where lead-free materials are required by code. It is compatible with all common solder alloys, including higher-melting non-lead-bearing alloys, and works with 95/5, 50/50, 40/60, and 60/40 solder blends. Licensed plumbers and pipefitters working in cold-weather regions or high-humidity environments will find the climate-stable formula particularly useful for maintaining consistent flux performance on the job site.
Works with all solders, including higher-melting non-lead-bearing alloys, as well as 95/5, 50/50, 40/60, and 60/40 solder blends. Suitable for use on copper pipe and fitting joints in standard plumbing installations.
This flux paste is applied by licensed plumbers during sweat-soldering of copper pipe joints. Before applying flux, ensure the water supply is shut off and the line is depressurized and dry. Apply a thin, even coat of paste to the fitting and pipe surfaces using the built-in brush, then heat and feed solder per standard practice. Follow all applicable IPC and local plumbing code requirements for lead-free solder use in potable water systems.
