Male-to-Female Threaded Reducing Bushing for Irrigation

Connect two different threaded sizes without rebuilding the surrounding irrigation pipework. This reducing bushing screws its larger male thread into a compatible female port and presents a smaller female thread for the next fitting. It can help make a size transition at a valve, filter, pump connection or irrigation manifold.

The angled view shows the outside male thread, recessed female opening and three grip ridges of this fitting style. It illustrates the shape of the bushing; read the selected option for the actual male and female sizes. The outside size and the inside size are different measurements.

Choose a matching pair

Each purchase option lists its outside male thread first and its inside female thread second. Available combinations range from a 3/4-inch male by 1/2-inch female bushing to 2-inch male options with several smaller female openings. Do not order by the larger size alone: two bushings can fit the same port yet provide different outlets.

Check the thread form and seal

Confirm the thread standard, not just its nominal size, on both mating parts. Different standards or damaged threads may appear close in size but will not make a reliable joint. Follow the sealing method specified for the components you are joining and avoid overtightening a plastic bushing. The ridged outer collar provides a place to grip the fitting during assembly; keep tools from deforming the threads or opening.

Fit and test the connection

Turn off the water and relieve pressure. Clean the female port, start the outer thread squarely, then install the smaller male fitting into the inner opening. Support attached pipework rather than letting its weight twist the adaptor. Restore the water slowly and inspect both joints while the system runs.

Sold as one reducing bushing. Mating fittings and any required sealing accessories are separate.
