The Copperman Copcal Capillary Slip Coupler is a -grade copper plumbing repair fitting engineered to establish a reliable, permanent inline connection between two copper pipe sections. Differing from standard straight couplers, it is manufactured with a completely smooth internal design without a central ridge stop, enabling the entire sleeve to slide entirely over a pipe section to easily bridge gaps in rigid, non-movable lines. This professional-grade fitting features precision-machined solder sockets on both ends, utilizing a capillary action mechanism when heated with plumbing flux and wire solder to ensure a perfectly uniform, leak-proof bond. Built for hot and cold residential water infrastructure, commercial maintenance, and emergency pipeline remediation, it delivers superior resistance to high hydraulic pressure, corrosion, and intense thermal stress.
