Directedair dabn-05xc 1/2 in Close Black Pipe Nipple

Product Description

The DIRECTEDAIR dabn-05xc is a close-pattern black pipe nipple with a 1/2 inch nominal pipe size. A close nipple consists of two threaded ends with no unthreaded center section, making the overall length equal to the combined length of both threaded portions. This fitting is manufactured from black steel, which is standard for gas line, steam, and industrial piping applications where galvanized coating is not required or preferred. Plumbers, pipefitters, and HVAC technicians install this type of fitting to create tight connections in piping assemblies where minimal spacing between two fittings or valves is needed.

This close nipple is suited for residential and commercial applications including natural gas supply lines, propane distribution, steam systems, and general industrial piping runs. The black steel construction makes it appropriate for dry or low-moisture environments where corrosion resistance from galvanizing is not a project requirement. It is commonly used in mechanical rooms, boiler rooms, and gas appliance connections where a compact, zero-clearance nipple is specified.

Key Features

• Close pattern — no unthreaded center section for minimal installed length
• 1/2 inch nominal pipe size with standard NPT threading on both ends
• Black steel construction suitable for gas, steam, and industrial piping
• Compatible with standard malleable iron, black steel, and cast fittings

Compatibility

Designed as an OEM-style replacement or standard-stock fitting for 1/2 inch NPT threaded piping systems in residential and commercial gas, steam, and industrial applications.

Installation Notes

Installation should be performed by a licensed plumber or pipefitter in accordance with applicable local codes, IFGC requirements for gas piping, and ASME B31 piping standards where applicable. Shut off and depressurize the gas or fluid supply before removing or installing any threaded pipe fitting. Apply an approved thread sealant or PTFE tape rated for the intended service medium before making up the joint. Do not over-tighten close nipples, as the lack of a wrench-flat center section makes removal difficult once fully engaged.
