The threads at two ends can be the same or different types, such as NPT thread to BSP thread nipples are also exist. And it is one of the most popular categories of pipe fittings, a combination of pipe nipples is recommended for low-pressure discharge and suction service for various compatible liquids and not for compressible products like air, nitrogen, or steam.

Barrel Nipple Types

The barrel nipple have many types. There are carbon steel pipe nipples, stainless steel pipe nipples, galvanized steel pipe nipples, black steel/iron pipe nipples, welded pipe nipples, seamless pipe nipples. And the length of the nipple is usually specified by the total length of the threaded portion. Also, it may have a hexagonal section in the center for a wrench to grasp (we call hex nipple), or it may simply make from a piece of straight pipe (we call it to barrel nipple or pipe nipple). When the nipple ends are of two different sizes it is called a reducer or unequal nipple, and threads used on nipples are BSP, BSPT, NPT, NPSM, and Metric.

There is a special style of pipe nipple called a hose nipple used for connecting threaded pipes and smooth hose. One end of the nipple is an external thread and the other end is a hose barb.
