The BMI USA 4574 is a lead-free, ready-cut threaded brass pipe nipple sized at 3/4 inch diameter by 16 inches in length. Designed for use in potable water, hydronic heating, and general plumbing systems, this fitting delivers a pre-cut, pre-threaded solution that eliminates field cutting and threading on the job. The red finish aids in quick visual identification on the job site. At 1.81 pounds, the fitting is solid brass construction throughout, providing corrosion resistance and long service life in both hot and cold water applications. Licensed plumbers and pipefitters are the primary installers of this product type.
This ready-cut pipe is suited for residential and light commercial plumbing installations where a 3/4-inch threaded connection is required. Common applications include supply line runs, boiler connections, water heater piping, and general distribution piping where a pre-threaded nipple of a specific length simplifies rough-in work. The lead-free construction meets requirements for potable water service in compliance with applicable safe drinking water standards.
Designed as an OEM-style replacement and standard threaded pipe nipple for use with 3/4-inch NPT fittings, valves, and couplings in residential and light commercial plumbing systems.
Installation should be performed by a licensed plumber in accordance with the International Plumbing Code (IPC) and applicable local codes. Shut off the water supply and depressurize the line before beginning work. Apply an appropriate thread sealant or PTFE tape to the male threads before making up connections. Do not over-tighten threaded joints, as brass fittings can crack under excessive torque.
