A Coupling fitting is a small but useful part in pipe installation. It connects two pipe ends, extends a pipe run, or helps repair a damaged section after the old pipe is cut out. In threaded systems, the worker can install it with seal tape or sealing paste and a pipe wrench. In socket weld systems, the Coupling fitting is welded in place when the line needs a stronger permanent joint.
This product can be made as carbon steel, galvanized steel, or stainless steel. The outside shape looks simple, but the inner bore, thread length, opening edge, and wall thickness all affect how it fits with the pipe. This product with rough thread may damage the pipe end or need too much force during installation, so thread cleaning and sampling checks are useful before goods are boxed.
