The pipe nipple is a short pipe typically with external/male threads on both ends. As connectors between two pipes, they can transport water, air, oil, natural gas, etc. Hebei Sanvo is the top pipe nipple supplier and manufacturer in China, focusing on the production and export of various high-quality pipe nipples. Currently, our factory supplies pipe nipples, mainly made of carbon steel, 304/316 stainless steel, or brass, with variations in surface finish. The pipe nipple sizes are American standard 1/8"-8", German standard DN6-DN150, British standard 1/8"-6", etc. The end type is TOE or TBE. The pipe types of pipe nipples are weld pipes or seamless pipes. Sanvo has been serving customers worldwide and is committed to ensuring the quality of our products while offering the most reasonable prices.

You will find the most direct, yet detailed answers to basic questions, you often ask about carbon and stainless steel pipe nipples.
Without further ado, here we go:
In plumbing and piping, a nipple is a fitting, consisting of a short piece of pipe, usually provided with a male pipe thread at each end, for connecting two other fittings.
The length of the nipple is usually specified by the overall length with thread. It may have a hexagonal section in the center for a wrench to grasp (sometimes referred to as a "hex nipple"), or it may simply be made from a short piece of pipe (sometimes referred to as a "barrel nipple" or "pipe nipple"). A "close nipple" has no unthreaded area; when screwed tightly between two female fittings, very little of the nipple remains exposed. A close nipple can only be unscrewed by gripping one threaded end with a pipe wrench which will damage the threads and necessitate replacing the nipple, or by using a specialty tool known as a nipple wrench (or known as an internal pipe wrench) which grips the inside of the pipe, leaving the threads undamaged. When the ends are of two different sizes it is called a reducer or unequal nipple.
Threads used on nipples are BSP, BSPT, NPT, NPSM, and Metric.
