The RECTORSEAL CORPORATION 14020 is an 8-ounce jar of Nokorode Regular Paste Flux, a professional-grade soldering flux used in plumbing and mechanical piping work. The paste formula applies cleanly to copper, brass, and other metal fittings before soldering, promoting proper solder flow and strong joint adhesion. The jar features a brush cap lid for controlled, mess-free application directly in the field. The 14020 is lead free and compatible with all standard solder alloys, including 95/5 and other lead-free solder formulations. It produces no odor during use and will not freeze or decompose under normal storage and job-site conditions.
This flux is suited for residential and light commercial plumbing installations and repairs involving sweat-soldered copper pipe and fittings. It is a go-to product for licensed plumbers working on potable water supply lines, hydronic heating systems, refrigeration piping, and general mechanical piping. The brush cap lid makes it practical for single-handed application when working in tight spaces around existing pipe runs. Sold individually by the 8-ounce unit.
Recommended for use with all solder alloys, including 95/5 and lead-free solder formulations. Designed as a general-purpose paste flux for sweat-soldering copper and brass pipe fittings in plumbing and mechanical piping applications.
Applied by licensed plumbers as part of standard sweat-soldering procedures under IPC and IFGC guidelines where applicable. Before soldering, shut off the water supply and ensure pipe ends are clean, dry, and free of burrs or oxidation. Apply flux sparingly to the pipe end and fitting socket using the integrated brush cap before assembling and heating the joint. Avoid over-application, as excess flux left on completed joints should be wiped away to prevent long-term corrosion.
