The BMI USA 4993 is a lead-free brass threaded pipe nipple designed for use in potable water, plumbing distribution, and fluid-handling systems where code compliance and corrosion resistance are required. At 11 inches in length and 2 inches in diameter, this close-cut nipple provides a reliable threaded connection between fittings, valves, and piping components. Constructed from solid brass with a red finish, the 4993 meets lead-free material standards applicable to drinking water systems. Licensed plumbers and pipefitters select this type of fitting for both new construction and retrofit applications.
This nipple is suited for residential and light commercial plumbing installations where 2-inch threaded connections are required. Common applications include water supply lines, manifold assemblies, boiler piping, and hydronic distribution systems. The threaded ends mate with standard NPT fittings, making it a straightforward drop-in component during system assembly or repair. Its lead-free brass construction makes it appropriate for potable water service in jurisdictions enforcing current lead-free plumbing codes.
Designed as an OEM-style replacement or new-installation threaded nipple for 2-inch NPT plumbing systems in residential and commercial applications.
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 any threaded fitting. Apply an appropriate thread sealant or PTFE tape to the male threads before making up the joint. Do not over-tighten, as excessive torque can crack fittings or damage threads.
