The BMI USA 4272 is a lead-free brass threaded nipple designed for use in potable water, plumbing, and fluid distribution systems. It measures 1/4 inch in diameter and 12 inches in length, providing a reliable threaded connection between piping components. Constructed from solid brass with a red finish, this nipple offers corrosion resistance and durability in both hot and cold water applications. Its lead-free construction meets modern plumbing code requirements for drinking water systems. Licensed plumbers and pipefitters are the primary installers of this type of fitting.
This nipple is suited for residential and light commercial plumbing installations where a 1/4-inch threaded connection point is required. Common applications include water supply lines, distribution manifolds, and equipment connections in HVAC and plumbing systems. The 12-inch length accommodates situations where standard short nipples cannot bridge the required gap between fittings, valves, or equipment ports.
Designed as an OEM-style replacement or standard component for 1/4-inch NPT threaded plumbing and fluid system assemblies in residential and commercial applications.
Installation of threaded brass nipples is typically performed by a licensed plumber in accordance with the applicable edition of the International Plumbing Code (IPC) or local equivalent. Shut off the water supply and depressurize the line before making any threaded connections. Apply thread sealant tape or compound to the male threads before assembly to ensure a leak-free joint. Do not over-tighten brass fittings, as the material can crack under excessive torque.
