The BMI USA 4051 is a lead-free brass threaded nipple designed for use in potable water, plumbing, and fluid-handling systems where code-compliant, low-lead fittings are required. Measuring 2.5 inches in diameter by 11 inches in length, this nipple provides a reliable threaded connection between pipes, valves, and fittings. Constructed from brass with a red finish, it delivers solid corrosion resistance and durability in both residential and commercial plumbing applications. Licensed plumbers and pipefitters are the primary installers of this type of fitting.
This brass nipple is suited for water supply lines, distribution manifolds, and general plumbing connections where a longer nipple length is needed to bridge fixtures or components. The lead-free construction meets safe drinking water compliance requirements, making it appropriate for use in potable water systems. Its threaded ends allow straightforward integration with standard NPT-threaded valves, unions, and fittings.
Designed as an OEM-style threaded nipple replacement suitable for standard NPT plumbing systems requiring lead-free brass fittings in residential and commercial installations.
Installation should be performed by a licensed plumber in accordance with applicable local plumbing codes and the International Plumbing Code (IPC). Shut off the water supply and relieve system pressure before removing or installing any threaded fittings. Apply an appropriate thread sealant or PTFE tape to the threaded ends before making up the connection. Do not overtighten, as excessive force can crack fittings or damage mating threads.
