Asc Engineered Solutions 8700143707 Black Iron Pipe Nipple

Product Description

The ASC Engineered Solutions 8700143707 is a black iron pipe nipple used in threaded pipe assemblies across residential and commercial plumbing, HVAC, and gas distribution systems. Manufactured from welded steel with a black oxide coating, it resists rust and corrosion in dry and low-moisture environments. At 1-1/2 inches in diameter and 6 inches in length, this Schedule 40 nipple meets ASTM A53 standards and carries standard NPT threads on both ends. It is sold individually and weighs 1.136 pounds. Plumbers, pipefitters, and HVAC technicians use this fitting to extend or connect threaded pipe runs in gas, steam, air, and water systems.

This nipple is suited for use in residential and light commercial applications where Schedule 40 black iron pipe is specified. Common installations include natural gas supply lines, propane distribution, steam heating systems, compressed air lines, and general industrial piping. The black coating distinguishes it from galvanized fittings and makes it the correct choice for gas service in many jurisdictions where galvanized pipe is not permitted on the downstream side of a gas meter.

Key Features

• Welded steel construction meets ASTM A53 standard for pressure pipe applications
• Schedule 40 wall thickness for standard-duty gas, air, steam, and water service
• Black oxide coating helps prevent corrosion and identifies the fitting as non-galvanized
• Standard NPT threads on both ends for compatibility with threaded fittings and valves
• 1-1/2 inch nominal diameter by 6 inch length — a commonly stocked close and run configuration
• Sold as an individual unit (each)

Compatibility

Designed as a standard replacement or new-installation Schedule 40 black iron pipe nipple compatible with 1-1/2 inch NPT threaded fittings, couplings, valves, and pipe in gas, steam, air, and water piping systems.

Installation Notes

Black iron pipe nipples are installed by licensed plumbers, pipefitters, or HVAC technicians depending on the application and local code requirements. Always shut off the gas supply or depressurize the system before breaking into an existing threaded connection. Apply an approved thread sealant or PTFE tape rated for the service medium before making up threaded joints. For gas piping, installation must comply with applicable local codes and IFGC requirements, and the completed assembly must be pressure-tested and leak-checked before returning to service.
