The BMI USA 4011 is a lead-free brass threaded nipple designed for use in potable water, plumbing, and general fluid-handling systems. At 3 inches in length, this close-tolerance fitting provides a reliable, leak-resistant threaded connection between pipes or fittings. The brass construction offers corrosion resistance and durability suited to both residential and light commercial plumbing applications. Lead-free compliance makes this nipple appropriate for use in drinking water systems where low-lead or lead-free material standards apply. Licensed plumbers and pipefitters are the primary installers of this type of fitting.
This nipple is used in a wide range of plumbing installations including water supply lines, hot and cold distribution systems, boiler connections, and irrigation headers. It is well suited for residential and commercial applications where a short, externally threaded pipe section is needed to join two fittings, valves, or threaded ports. The 3-inch length accommodates installations that require a modest standoff between connection points.
Designed as an OEM-style threaded brass nipple for use with standard NPT-threaded fittings, valves, and pipe connections in residential and commercial plumbing systems.
Installation of threaded brass nipples is typically performed by a licensed plumber in accordance with the International Plumbing Code (IPC) or applicable local codes. Shut off the water supply and depressurize the line before installation. Apply an approved thread sealant tape or compound to the male threads before making up the connection. Do not over-torque brass fittings, as brass can crack under excessive force.
