Bmi Usa 10845 Black Steel Pipe Nipple 1.5x4.5 in

Product Description

The BMI USA 10845 is a black steel pipe nipple designed for use in threaded piping systems across plumbing, gas distribution, and mechanical installations. Measuring 1.5 inches in diameter and 4.5 inches in length, this close-cut nipple provides a rigid, durable threaded connection between fittings, valves, and pipe runs. Constructed from steel with a black finish, it is built to handle the demands of commercial and residential piping applications. Installation is performed by licensed plumbers or pipefitters working on gas, water, or hydronic systems.

This black steel nipple is commonly used in residential and light commercial gas piping, fire suppression headers, compressed air lines, and hydronic heating systems. The 1.5-inch diameter and 4.5-inch body length make it a standard utility nipple for close-quarter connections where additional length or flexibility is not needed. It threads directly into standard NPT fittings without adapters.

Key Features

• Black steel construction provides durability in gas and mechanical piping applications
• 1.5-inch diameter with NPT-compatible threaded ends
• 4.5-inch body length suits close-quarter pipe runs and fitting connections

Compatibility

Designed as an OEM-style replacement or direct-use fitting for standard 1.5-inch NPT threaded plumbing, gas, and mechanical piping systems.

Installation Notes

Installation should be performed by a licensed plumber or pipefitter in accordance with applicable codes such as the International Fuel Gas Code (IFGC) or International Plumbing Code (IPC). Shut off gas or water supply and depressurize the line before removing or installing any threaded fittings. Apply an approved thread sealant or PTFE tape rated for the intended service medium before threading the nipple into fittings. Hand-tighten first, then use a pipe wrench to achieve a proper seal without over-torquing.
