The BMI USA 4065 is a lead-free brass threaded pipe nipple measuring 3 inches in diameter and 12 inches in length. Designed for use in potable water, plumbing, and general fluid-handling systems, this nipple provides a reliable, corrosion-resistant connection between threaded fittings, valves, and piping components. The brass construction offers excellent durability and resistance to dezincification in water supply applications. At 8.49 pounds, this is a full-size nipple suited for commercial and residential plumbing installations where lead-free compliance is required by code.
This nipple is appropriate for use in water distribution systems, HVAC hydronic piping, and general-purpose plumbing where a 3-inch threaded male connection is needed. The 12-inch length makes it suitable for close-coupling fixtures, bypasses, and manifold assemblies. Licensed plumbers and pipefitters typically install this fitting in both new construction and retrofit applications where NPT-threaded connections are standard.
Designed as an OEM-style replacement and standard-use fitting compatible with 3-inch NPT-threaded valves, couplings, and pipe fittings in residential and commercial plumbing systems.
Installation should be performed by a licensed plumber in accordance with applicable local plumbing codes and the International Plumbing Code (IPC). Shut off the water supply and relieve system pressure before threading the nipple into place. Apply thread sealant tape or pipe dope to the male threads prior to assembly to ensure a leak-free joint. Do not overtighten, as brass threads can be damaged by excessive force.
