The BMI USA 4052 is a lead-free brass threaded nipple designed for use in potable water and fluid-handling systems. Measuring 2.5 inches in diameter by 12 inches in length, this nipple provides a rigid, corrosion-resistant connection between threaded fittings, valves, and pipe runs. Constructed from brass with a red finish, it meets lead-free requirements for use in drinking water applications. Licensed plumbers and pipefitters install this type of nipple in both new construction and retrofit plumbing systems where a reliable, code-compliant threaded connection is required.
This nipple is suited for residential and light commercial plumbing installations where a 2.5-inch threaded connection is needed at 12 inches of run length. Typical applications include water supply lines, boiler connections, and distribution manifold runs. Its lead-free brass construction makes it appropriate for potable water systems subject to local or federal lead-free compliance requirements.
Designed as an OEM-style replacement or direct-install brass nipple for standard NPT threaded plumbing systems requiring a 2.5-inch by 12-inch fitting.
Installation should be performed by a licensed plumber in accordance with applicable local plumbing codes and IPC standards. Shut off the water supply and depressurize the line before removing or installing any threaded fitting. Apply thread sealant tape or compound rated for brass fittings to all threaded connections before assembly. Do not over-tighten threaded connections, as brass fittings can crack under excessive torque.
