Black Pipe Nipple: 1/2" Dia x 9" Long, Schedule 40 MPN:583-090HN

Black pipe nipples offer an economical way to join black pipes and provide extra strength where increased pressure is not necessary compared to Schedule 80. They feature male threads on both ends, making them easy to connect to black pipes or other fittings with the same thread type. The schedule 40 designation refers to its thickness and indicates that it can handle a maximum operating pressure of 150 PSI at 73 Fahrenheit and reduces the risk of collapse under moderate water pressure. This particular size, a 1/2 diameter by 9 long, is ideal for residential and commercial plumbing applications such as drainage systems, potable water delivery, irrigation or general piping installations where the system doesn't require additional pressure support offered by Schedule 80 pipe fittings.
