Asc Engineered Solutions 8700138350 Black Iron Close Nipple

Product Description

The ASC Engineered Solutions 8700138350 is a 1/2-inch Schedule 40 black iron close nipple used in threaded pipe assemblies for gas, steam, and water distribution systems. The close nipple configuration means the fitting is threaded end-to-end with minimal unthreaded center, allowing two fittings or valves to be connected in tight spaces. Constructed from welded steel with a black coating applied to slow surface oxidation, this nipple meets ASTM A53 standards for steel pipe. Licensed plumbers, pipefitters, and gas service technicians install this type of fitting in both residential and light commercial applications.

This close nipple is suited for low- to moderate-pressure threaded piping systems, including natural gas and propane supply lines, steam heating distribution, and potable or non-potable water supply runs. The Schedule 40 wall thickness provides adequate pressure rating for standard service conditions encountered in residential and commercial mechanical rooms, boiler rooms, and utility installations. Standard NPT threads ensure compatibility with conventional threaded fittings and valves across the trade.

Key Features

• Close nipple design allows back-to-back fitting connections in confined spaces
• Schedule 40 wall thickness meets standard service pressure requirements
• Welded steel construction with black coating for corrosion resistance
• Meets ASTM A53 standards for steel pipe fittings
• Standard NPT threads for straightforward assembly with common trade fittings

Compatibility

Designed as an OEM-style replacement or new-installation fitting compatible with standard 1/2-inch NPT threaded pipe systems in Schedule 40 black iron or steel configurations.

Installation Notes

Installation should be performed by a licensed plumber, pipefitter, or qualified gas technician in accordance with applicable local codes, the International Fuel Gas Code (IFGC), or the International Plumbing Code (IPC). Always shut off gas or water supply and depressurize the line before disassembling or installing threaded fittings. Apply an approved thread sealant or PTFE tape rated for the service medium before assembly. Do not over-tighten threaded connections, as this can crack fittings or damage threads.
