The BMI USA 4024 is a lead-free brass threaded nipple designed for use in potable water, plumbing, and fluid-handling systems where code compliance and corrosion resistance are required. At 4.5 inches in length and constructed from solid brass with a red finish, this nipple is built for reliable, leak-resistant connections in both residential and light commercial applications. Its lead-free construction meets current standards for use in drinking water systems. Licensed plumbers and pipefitters are the primary installers of this fitting type.
This nipple is suited for residential and commercial plumbing installations where a short-run threaded connection is needed between valves, fittings, or equipment. The 4.5-inch length makes it appropriate for close-quarter rough-in work, boiler trim, water heater connections, and similar service scenarios. It is typically used with NPT-threaded fittings and components.
Designed as an OEM-style replacement or standard-use threaded brass nipple compatible with NPT-threaded plumbing valves, fittings, and equipment in residential and commercial 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 removing or installing threaded nipples. Apply thread sealant tape or compound to male threads before assembly. Do not over-tighten, as excessive force can crack fittings or damage threads.
