The BMI USA 4015 is a lead-free brass threaded pipe nipple designed for use in potable water, plumbing, and fluid-handling systems. Measuring 3 inches in diameter and 5 inches in length, this fitting connects threaded pipe sections in residential and light commercial installations. Constructed from brass with a red finish, the 4015 meets lead-free requirements for drinking water applications. Licensed plumbers and pipefitters install this nipple where a short, rigid threaded connection is needed between valves, fittings, or equipment ports.
This nipple is suited for residential and commercial plumbing rough-in and service work. Common applications include water supply lines, boiler connections, hydronic heating systems, and general fluid distribution where a durable brass threaded fitting is required. The lead-free construction makes it appropriate for potable water systems subject to safe drinking water regulations.
Designed as an OEM-style replacement or new-installation brass threaded pipe nipple for use with standard 3-inch threaded pipe fittings and valves in plumbing and fluid-handling systems.
Installation should be performed by a licensed plumber in accordance with local plumbing codes and the International Plumbing Code (IPC). 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 overtighten, as this can crack fittings or damage seating surfaces.
