DWC Fittings (Double Wall Corrugated Pipe Fittings) are accessories used to connect, divert, or terminate DWC pipes in underground cable protection and drainage systems. These fittings ensure a secure, leak-proof, and mechanically strong joint in DWC pipeline networks. DWC fittings are specially designed components made from HDPE or polypropylene that match the corrugated outer surface and smooth inner bore of DWC pipes. They help create bends, joints, and branches in underground duct systems.
