Asc Engineered Solutions 8700138657 Black Iron Nipple

Product Description

The ASC Engineered Solutions 8700138657 is a Schedule 40 black iron pipe nipple used in threaded pipe assemblies across plumbing, gas distribution, and industrial piping systems. Measuring 0.5 inches in diameter and 4 inches in length, this nipple is welded steel construction with a black coating applied to resist corrosion. Standard NPT threads on both ends allow direct connection to fittings, valves, and other threaded pipe components. Licensed plumbers, pipefitters, and gas service technicians install this type of nipple in both residential and commercial applications where a short threaded extension is needed between two fittings or at a connection point.

This nipple is suited for residential and light commercial piping work including natural gas lines, propane distribution, steam systems, and general water service where Schedule 40 wall thickness is specified. The black iron finish makes it a common choice for gas piping applications where galvanized fittings are not permitted by code. It is sold individually and is compatible with standard 0.5-inch NPT fittings and pipe components used throughout the trade.

Key Features

• Schedule 40 wall thickness meets standard pressure requirements for residential and commercial service
• Black coating applied over welded steel to inhibit surface rust during storage and service
• Standard NPT threads on both ends for compatibility with common threaded fittings and valves
• Meets ASTM A53 specifications for welded steel pipe
• Compact 4-inch length suitable for close-quarters connections between fittings

Compatibility

Designed as a standard-thread replacement or new-installation nipple for 0.5-inch NPT threaded piping systems. Compatible with Schedule 40 black iron fittings, couplings, valves, and pipe components using standard NPT thread form.

Installation Notes

Installation is performed by licensed plumbers or gas fitters in accordance with the International Fuel Gas Code or applicable local plumbing code. Shut off and depressurize the line completely before threading or removing any fittings. Apply an approved pipe thread sealant or PTFE tape rated for the intended service medium before making up the joint. Do not use black iron nipples in systems requiring galvanized or corrosion-resistant material as specified by local code.
