Bmi Usa 4003 Brass Nipple 2.5 X 3.5 Inches Lead Free

Product Description

The BMI USA 4003 is a lead-free brass nipple designed for threaded pipe assemblies in residential and commercial plumbing systems. At 2.5 inches nominal pipe size and 3.5 inches in length, this fitting connects threaded pipe runs where a short extension or transition is needed. Machined from solid brass with a red finish, it meets lead-free material requirements for potable water applications. Plumbers and pipefitters install this type of nipple as a standard component in supply lines, distribution manifolds, and fixture connections. Weighing 1.27 pounds, it is a solid, durable fitting built for reliable threaded assembly.

This brass nipple is suited for use in potable water supply systems, hydronic heating piping, and general plumbing distribution where NPT-threaded fittings are required. Its lead-free construction makes it appropriate for drinking water service lines and fixtures under current plumbing code requirements. Typical install scenarios include connecting valves, tees, elbows, or other fittings in residential supply systems and light commercial plumbing applications.

Installation Notes

Installation of threaded brass nipples is performed by licensed plumbers in accordance with the International Plumbing Code (IPC) and applicable local codes. Shut off the water supply and relieve system pressure before removing or installing any threaded fitting. Apply an appropriate thread sealant or PTFE tape to the male threads before assembly. Do not over-tighten, as excessive torque can crack brass fittings or distort threads.
