A Galvanized Threaded Coupling is a steel pipe fitting with internal threads and a zinc-coated outer and inner surface. It is mainly used to join two threaded pipes or nipples in low to medium pressure pipe work, such as building water lines, air lines, guard rail posts, irrigation fittings, and general repair work. The galvanized surface helps slow surface rust when the coupling is stored, shipped, or installed in a damp place.
The Galvanized Threaded Coupling is not a complex part, but the thread needs to be clean and the coating should not block the thread form. For this reason, size inspection and thread go/no-go checks are important before packing. Common orders include small sizes for plumbing use and larger sizes for steel pipe assemblies. This product can also be supplied with different thread standards when the end user works with NPT, BSPT, or other pipe thread systems.
