Assorted Plumbing and Industrial Pipe Fittings and Adapters

This image displays a collection of used and new plumbing and industrial fittings, adapters, and pipe sections contained within a grey plastic bin. The items vary significantly in size, ranging from small brass and galvanized steel nuts and connectors to larger black iron pipe elbows and threaded pipe segments. Materials primarily include black iron (cast iron or steel with a black protective coating), galvanized steel (silver-colored, zinc-coated steel), brass (yellowish metal), and some possibly stainless steel components. The overall color palette is metallic, featuring dark greys, silvers, and brassy yellows, with some instances of rust coloration on iron parts and a pale green residue on one elbow. Construction methods include threaded connections (both male and female), compression fittings, and possibly some flared fittings, indicating a variety of applications from water systems to hydraulic or pneumatic lines. Many pieces exhibit signs of wear, including scratches, dirt, corrosion, and patina consistent with age and previous use. Some threads appear worn or filled with debris. Notable features include various types of elbows (90-degree and 45-degree), straight connectors, reducers, caps, and unions. Visible markings are present on some pieces, such as what appears to be "CHINA" stamped on a black iron elbow, indicating manufacturing origin. The variety of sizes and types suggests a collection accumulated over time, possibly spare parts or items salvaged from a project. The condition varies from relatively clean to heavily soiled and corroded, implying that some items may be salvageable for reuse, while others might be for scrap or specific repair needs. There are no discernible maker's marks besides the country of origin.
