Sink Waste Coupler

A durable brass sink waste coupler meticulously designed for efficient drainage in kitchen and bathroom sink installations. Manufactured from high-quality CDA C36000 brass alloy, this coupler provides exceptional resistance to corrosion, tarnishing, and mineral buildup even in hard water environments. The precision-machined threading guarantees a perfect, leak-free connection with standard sink drain assemblies, waste traps, and outlet pipes. Featuring a robust wall thickness for lasting structural integrity, the coupler withstands daily thermal cycling from hot and cold water use without developing fatigue cracks or loosening. Available in standard sizes from 1-1/4 inch to 2 inches to accommodate various sink configurations. The smooth internal bore ensures unrestricted water flow, minimizing the risk of clogging. Suitable for residential kitchens, commercial restaurants, hospital washrooms, and laboratory sink systems where reliable, hygienic drainage is essential.
