Setup, Compatibility & Care
To install this coupling, you will need a pipe cutter, a deburring tool, high-quality plumbing flux, lead-free solder, and a butane or propane blowtorch. First, ensure the 15mm and 12mm copper pipes are cut cleanly and square. Deburr the inside and outside of the pipe ends to ensure they seat fully into the coupling. Apply a thin, even layer of flux to both the pipe end and the interior of the fitting. Slide the fitting into place, heat the joint uniformly, and introduce the solder wire to the edge of the fitting. The solder will be drawn into the joint. Allow the connection to cool naturally; do not quench with cold water to avoid inducing stress in the copper. These fittings are intended for copper-to-copper connections only and are not compatible with PEX or PVC piping systems.
