The reducing hex nipple is a versatile fitting used in pneumatic, hydraulic, plumbing, and gas systems. Its hexagonal body allows easy tightening with a wrench, while the dual male threaded ends of different diameters provide a secure, leak-resistant transition between dissimilar pipe sizes.
As a BSP (British Standard Pipe) fitting, it features a 55° thread angle, making it compatible with a wide range of industrial and commercial equipment. Common configurations include 1/2″ BSP male on one end and 3/8″ or 1/4″ BSP male on the other, ideal for connecting air lines, fluid systems, or gas appliances.
