Product details
A waste coupling, or drain coupling, is a plumbing connector that connects the drain of a basin, sink, or bathtub to the main drainage system. Its purpose is to channel wastewater and debris away while preventing clogs, leaks, and foul odors. Waste couplings come in several varieties, depending on the sink or basin design and required functionality. For durability and corrosion resistance, choose brass or stainless steel. Plastic couplings are a more budget-friendly option.
