A nipple in plumbing is identified by what measurements?

In plumbing, a nipple refers to a short length of pipe that is used to connect two other fittings or pipes. The specific identification of a nipple is based on both its diameter and its length. The diameter is critical because it indicates the size of the connections it can accommodate, which is essential for ensuring proper flow and compatibility with other plumbing fixtures. The length is equally important, as it determines the physical distance between the connections, affecting how the installation fits within the overall plumbing layout.

Thus, to accurately identify a nipple, one must specify both the diameter that fits into existing systems and the length that ensures correct reach or placement between other plumbing components. This two-fold measurement ensures that the nipple will function effectively in its intended application without leakage or improper fit. The inclusion of both measurements provides a complete picture of the nipple, which is crucial for successful plumbing installations.
