Cambridge Resources fnb12x5 Black Steel Pipe Nipple

Product Description

The CAMBRIDGE RESOURCES fnb12x5 is a black steel pipe nipple measuring 0.5 inches in diameter by 5 inches in length. It is a short threaded pipe fitting used to connect sections of pipe or to join pipe to valves, couplings, and other fittings in low-pressure fluid and gas distribution systems. Manufactured to ASTM A733 specifications and hydrostatically tested, this nipple is built for reliable service in plumbing, HVAC, and mechanical piping applications. Licensed plumbers and pipefitters install this type of fitting during rough-in work and system assembly.

This black steel nipple is suited for use in residential and commercial piping systems where black iron pipe is specified. Common applications include natural gas supply lines, steam systems, and general-purpose water distribution where corrosion resistance from black oxide finish is acceptable. The 0.5-inch nominal pipe size fits standard half-inch threaded pipe systems. Installers use this nipple in both new construction and retrofit applications where a short close-nipple run is required between two threaded connections.

Key Features

• Manufactured to ASTM A733 specifications for dimensional and material consistency
• Hydrostatically tested to verify pressure integrity before shipment
• Steel construction for durability in gas and fluid piping systems
• Standard threaded ends for compatibility with NPT fittings and valves
• Black steel finish suited for gas and steam service applications

Compatibility

Designed as an OEM-style replacement or standard component fitting for 0.5-inch NPT threaded black iron pipe systems used in residential and commercial plumbing and gas piping applications.

Installation Notes

Installation of black steel pipe nipples in gas service must be performed by a licensed plumber or pipefitter in accordance with applicable codes, including IFGC and local amendments. Shut off the gas supply and depressurize the line before disassembling any threaded connections. Apply an approved thread sealant or PTFE tape rated for gas service to all threaded joints. Inspect threads for damage before assembly and do not overtighten, as this can crack fittings or distort threads.
