Abstract
A nipple valve-type waterer is provided for a live stock watering system. This nipple valve comprises a generally cylindrical, tubular valve body of greater diameter than a tubular, water delivery manifold. The tubular valve body is provided in two valve body halves which interfit in surrounding relation with the manifold. The manifold is provided with a pair of coaxially aligned through openings, while a through axial bore in each tubular valve body half is coaxially aligned with one of these manifold through openings as the valve body halves are fitted in surrounding relation to the manifold. The nipple valve also provides a flow path for guiding water from the supply manifold to and through the valve body, and seals are carried in the valve body for preventing leakage between the manifold and the valve where they interfit.
