Standard Black Nipples

Standard black pipe nipples are threaded steel pipe fittings used to connect two female threaded fittings or extend pipe runs in plumbing, mechanical, and industrial piping systems. These nipples are manufactured from black steel pipe and feature male NPT threads on both ends, making them ideal for general piping applications including plumbing, compressed air, and industrial systems.

Standard black pipe nipples are typically produced from Schedule 40 steel pipe and are available in multiple diameters and lengths including common sizes such as 1/8", 1/4", 1/2", 3/4", and 1" pipe nipples with lengths like close, 2", 3", 4", 6", and 12" threaded nipples.
