Asc Engineered Solutions 8700142451 Black Iron Pipe Nipple

Product Description

The ASC Engineered Solutions 8700142451 is a black iron pipe nipple used to connect sections of threaded pipe in residential and commercial plumbing, gas distribution, and mechanical piping systems. It measures 1-1/4 inches in diameter and 5-1/2 inches in length, manufactured from welded steel with a black coating applied to resist corrosion during storage and service. The Schedule 40 wall thickness meets standard pressure ratings for typical low-pressure gas and water applications. Standard NPT threads on both ends allow straightforward assembly with compatible fittings, valves, and pipe sections. Licensed plumbers, pipefitters, and HVAC mechanical contractors are the primary installers of this component.

This nipple is suited for use in gas supply lines, steam systems, hydronic heating loops, and general industrial piping where threaded black iron pipe is specified. It is commonly used in both new construction and retrofit applications requiring a short close-to-medium length threaded connector between fittings. The Schedule 40 wall rating makes it appropriate for standard-pressure service in residential and light commercial installations.

Key Features

• Black-coated welded steel construction resists corrosion during installation and service
• Schedule 40 wall thickness rated for standard pressure applications
• Standard NPT threads on both ends for compatibility with common threaded fittings
• Meets ASTM A53 standards for welded steel pipe
• 1-1/4 inch diameter x 5-1/2 inch length for close-to-medium span connections

Compatibility

Designed as an OEM-style replacement or standard component for Schedule 40 threaded black iron pipe systems using 1-1/4 inch nominal pipe size fittings, valves, and couplings.

Installation Notes

Installation should be performed by a licensed plumber or pipefitter in accordance with applicable local mechanical and plumbing codes, including IPC and IFGC requirements where gas service is involved. Shut off all gas or fluid supply and depressurize the line before disassembly or installation. Apply an appropriate thread sealant or PTFE tape rated for the service medium to all NPT threads before assembly. Do not over-tighten threaded connections, as this can damage fittings or crack cast iron components in the assembly.
