Threaded Reducing Coupling (Threaded Forged Fittings)
Joins two pipes of different diameters in a straight line, without a separate reducer fitting.
Overview
A Threaded Reducing Coupling is a forged, small-bore fitting that joins two pipes of different diameters in a straight line, without a separate reducer fitting. It connects via NPT/BSPT threads, screwing directly onto the mating pipe or fitting with no welding required, and is machined from a solid forged billet for superior strength over a cast equivalent.
Royal Steel India manufactures Threaded Reducing Coupling to ASME B16.11 dimensions for high-pressure, small-bore piping systems across process, utility and instrumentation applications.
