A sink coupling is a vital plumbing component used to connect the sink drain to the waste pipe, ensuring a secure and leak-proof joint. Typically made from durable materials such as stainless steel, brass, or PVC, sink couplings are designed to withstand constant exposure to water and resist corrosion. They play a critical role in efficiently channeling wastewater from the sink to the drainage system while preventing leaks and water damage. Easy to install and available in various sizes, sink couplings are compatible with a range of sink types, from kitchen to bathroom sinks. In addition to functionality, they help maintain proper drainage and ensure a hygienic environment by preventing waste buildup in the pipe system.
