A wash basin waste coupling is a key bathroom fitting that helps manage wastewater by efficiently connecting the basin outlet to the drainage pipe. Made from brass or stainless steel with a polished chrome finish, it offers long service life and corrosion resistance. The coupling features holes or perforations on the cap, which allow water to drain quickly while capturing solid waste and preventing blockages.

Most models include high-quality rubber washers to ensure a leak-proof seal and support tool-free installation. With universal dimensions, this coupling suits most ceramic, marble, and steel sinks in residential or commercial settings.

Features:

• Constructed from durable brass or stainless steel with chrome plating

• Standard diameter sizes: 3.2–4 cm (1¼" to 1½") fits most basin outlets

• Height: usually 7.5–10 cm

• Leak-proof rubber washers included

• Anti-clog perforated top for debris retention

• Rust- and stain-resistant polished finish

• Quick installation with standard plumbing tools or hand tightening
