Bmi 10740 Black Pipe Nipple 1.25 X 4 Inches

Product Description

The BMI 10740 is a black steel pipe nipple used to connect threaded pipe fittings in gas, water, and general-purpose piping systems. At 1.25 inches in diameter and 4 inches in length, this close-cut threaded nipple bridges fittings, valves, and other threaded components in both residential and light commercial applications. The black steel construction makes it a standard choice for gas distribution lines where galvanized material is not permitted. Plumbers, pipefitters, and HVAC technicians install this type of nipple as a routine part of any threaded iron pipe assembly.

This nipple is suited for gas supply piping, steam systems, and general iron pipe installations in both residential and commercial settings. Its 1.25-inch nominal pipe size fits standard NPT threaded fittings of the same diameter. The 4-inch body length provides a short, rigid extension between two threaded connection points, making it useful in tight runs where a longer nipple would be impractical.

Key Features

• Black steel construction suitable for natural gas and propane supply lines
• 1.25-inch nominal pipe size with standard NPT threading on both ends
• 4-inch body length for short-run threaded connections
• Compatible with standard black iron pipe fittings, valves, and unions
• Lightweight at 0.296 pounds for easy handling and installation

Compatibility

Designed as a standard replacement or new-installation nipple for 1.25-inch NPT threaded iron pipe systems. Fits standard black iron pipe fittings, couplings, tees, elbows, and valves of the same nominal pipe size.

Installation Notes

Installation should be performed by a licensed plumber or pipefitter in accordance with local plumbing and mechanical codes, including applicable IFGC requirements for gas piping. Shut off the gas supply or isolate the water line completely before disassembling any existing threaded connection. Apply an approved thread sealant or PTFE tape rated for the intended service before making up threaded joints. Inspect all connections for leaks after pressurizing the system.
