Asc Engineered Solutions 8700142055 Black Iron Close Nipple

Product Description

The ASC Engineered Solutions 8700142055 is a close-pattern black iron pipe nipple manufactured from welded Schedule 40 steel. It is black coated to resist corrosion and threaded on both ends with standard NPT pipe thread. Close nipples have no unthreaded center section, making them the correct choice when two fittings must be joined with minimal spacing. This nipple is sized at 1-1/4 inches and is used in gas, steam, air, and water piping systems. It meets ASTM A53 standards for welded steel pipe. Licensed plumbers, pipefitters, and HVAC technicians are the typical installers.

This close nipple is suited for residential and light commercial piping installations where a short, rigid connection is required between two threaded fittings. Common applications include natural gas supply lines, compressed air distribution, steam systems, and hydronic heating piping. The 1-1/4 inch size fits standard full-port fittings and valves of the same nominal diameter. The black iron coating distinguishes it from galvanized pipe and is the accepted material for interior gas piping in most jurisdictions.

Key Features

• Close pattern — no unthreaded center section for tight fitting-to-fitting connections

Compatibility

Designed as an OEM-style replacement and standard-use close nipple for 1-1/4 inch NPT threaded piping systems in gas, steam, air, and water service applications.

Installation Notes

Installation should be performed by a licensed plumber, pipefitter, or qualified HVAC technician in accordance with applicable local codes, IFGC requirements for gas applications, and IPC requirements for water or steam applications. Shut off gas supply or depressurize the system fully before making or breaking any threaded connections. Apply appropriate thread sealant or PTFE tape rated for the service medium before assembly. Do not over-torque threaded connections, as this can crack fittings or distort threads.
