Measuring 12 inches in length with a 3/8-inch diameter, this nipple serves as a pipe extension or connector between threaded fittings and valves. Machined from brass with a red finish, it meets lead-free material requirements applicable to drinking water installations. Licensed plumbers install this type of fitting during new construction, renovation, and repair work on residential and light commercial plumbing systems.
This nipple is suited for residential and light commercial plumbing applications where a 3/8-inch threaded connection is required. Typical uses include connecting supply lines to fixtures, valves, or manifolds in potable water systems. The 12-inch length accommodates installations that require additional reach between threaded connection points. Its brass construction makes it appropriate for both hot and cold water service lines.
Designed as an OEM-style replacement or direct-install fitting for 3/8-inch threaded plumbing connections in residential and light commercial potable water systems.
Installation is performed by a licensed plumber in accordance with local plumbing codes and the International Plumbing Code (IPC). Shut off the water supply and relieve system pressure before threading this nipple into place. Apply thread sealant tape or pipe joint compound to the male threads before assembly. Do not overtighten threaded connections, as brass fittings can be damaged by excessive torque.
