The BMI USA 4720 is a lead-free brass threaded nipple designed for use in pressurized pipe systems where safe, reliable connections are required. Measuring 1-1/4 inches in diameter and 2 inches in length, this nipple serves as a short extension or transition fitting between threaded pipe sections. Constructed from brass with a red finish, it is suited for licensed plumbers and pipefitters working on potable water, hydronic heating, and general fluid-transfer applications. Its lead-free construction meets requirements for use in drinking water systems under applicable plumbing codes.
This fitting is commonly installed in residential and light commercial plumbing systems where 1-1/4-inch threaded pipe connections are required. Typical applications include water supply lines, boiler piping, and hydronic distribution systems. The 2-inch body length makes it useful in close-quarter installations where a longer nipple would not fit and a standard hex nipple would be too short. Plumbers installing potable water systems will find this fitting appropriate wherever lead-free compliance is mandatory under state or local code.
Designed as an OEM-style replacement or standard service fitting for 1-1/4-inch NPT threaded plumbing systems. Also referenced under BMI Canada part number 04720.
Installation should be performed by a licensed plumber in accordance with the International Plumbing Code (IPC) or applicable local plumbing code. Shut off the water supply and relieve system pressure before removing or installing threaded fittings. Apply an appropriate thread sealant or PTFE tape to the male threads before assembly. Do not overtighten, as brass threads can be damaged by excessive torque.
