The RECTORSEAL CORPORATION 74026 is a 3-ounce jar of C-Flux, a lead-free soldering flux paste formulated with powdered solder for use in plumbing and HVAC piping work. The integrated powdered solder content provides additional material at the joint during the sweat-soldering process, reducing the risk of voids and helping produce leak-free connections. This flux is designed for professional use by licensed plumbers and HVAC technicians working on copper piping systems where reliable, leak-free joints are required.
C-Flux 74026 is suited for residential and light commercial copper pipe applications where soldering with soft solders is the joining method. It is compatible with 95/5, 60/40, 50/50, and 40/60 solder alloys, giving technicians flexibility across a range of job requirements. The lead-free formulation meets modern plumbing code requirements for potable water and other regulated piping systems.
Designed for use with 95/5, 60/40, 50/50, and 40/60 solder alloys on copper pipe and fittings in plumbing and HVAC piping applications.
Application of this flux is performed by licensed plumbers or HVAC technicians trained in sweat-soldering copper pipe. Before soldering, shut off and depressurize the piping system and ensure the pipe and fitting surfaces are clean and dry. Apply flux sparingly to both the pipe end and fitting cup, assemble the joint, and heat evenly before feeding solder. Follow all applicable local plumbing codes and IFGC or IPC requirements for soldered joints in your jurisdiction.
