The BMI USA 4930 is a lead-free brass nipple designed for threaded pipe connections in plumbing systems. At 3 inches in length with a 2-inch diameter, this close-pattern nipple provides a reliable, corrosion-resistant joint between threaded fittings, valves, and pipe sections. Constructed from solid brass with a red finish, it meets lead-free material standards required in potable water applications. Licensed plumbers and pipefitters install this type of fitting as part of supply line assemblies, fixture rough-ins, and equipment connections where a short, rigid threaded extension is needed.
This brass nipple is suited for residential and light commercial plumbing installations. It is commonly used in water supply lines, boiler piping, and general mechanical systems where a threaded male-to-male connection is required. The 3-inch body length provides clearance for unions, valves, or other inline components. Its lead-free construction makes it appropriate for use in potable water systems subject to current safe drinking water regulations.
Designed as an OEM-style replacement or standard component for residential and commercial threaded plumbing systems using 2-inch NPT connections.
Installation should be performed by a licensed plumber in accordance with applicable local plumbing codes and IPC guidelines. Shut off the water supply and relieve system pressure before removing or installing any threaded fitting. Apply an approved thread sealant or PTFE tape to the male threads before assembly, and tighten to hand-snug before using a pipe wrench — avoid over-torquing brass fittings. Inspect threads for damage before use and do not force mismatched or cross-threaded connections.
