The Parker brass hexagonal long nipple is a pipe fitting with male National Pipe Taper (NPT) threads on both ends for connecting and extending two pieces of female pipe. The long nipple is a longer version than the short, and is threaded on both ends with an expanse of plain unthreaded surface in the middle. It has male NPT threads for creating tighter seals than straight threads and is made from brass, which is more economical, and offers greater corrosion resistance than steel. The hexagonal shape allows for increased leverage with a wrench during installation and disassembly. This pipe fitting meets standards ANSI B31.1 and B1.20.1 for quality assurance Pipe fittings are components used for connecting, terminating, controlling flow, and changing the direction of piping in many different industries. When purchasing pipe fittings, consider the application, as this will affect material type, shape, size and required durability. Fittings are available threaded or unthreaded, in many shapes, styles, sizes, and schedules (pipe wall thickness). Parker Hannifin is a global manufacturer of motion and control technologies.
