CxC Reducer Coupling, U600R. Designed for maximum efficiency, allowing you to branch off a main line to a smaller pipe size with a single, compact fitting, reducing the need for extra adapters and potential leak points. Unlike cast fittings, the wrot (worked) copper manufacturing process results in a smoother interior surface for better flow rates and a stronger, thinner wall that is easier to heat and solder. Naturally lead-free and resistant to dezincification, this tee is a set-and-forget solution that maintains its structural integrity for the entire lifespan of the plumbing system.
