The ASC Engineered Solutions 8700141008 is a Schedule 40 black iron pipe nipple measuring 1 inch in diameter and 3 inches in length. Constructed from welded steel with a black coating applied to resist corrosion, this nipple provides a reliable threaded connection in gas, steam, and water piping systems. Standard pipe threads on both ends allow for straightforward integration into existing iron or steel pipe assemblies. Plumbers, pipefitters, and HVAC technicians use this type of fitting in both residential and commercial mechanical installations where iron pipe is specified. The part meets ASTM A53 standards, confirming it is manufactured to recognized industry material and performance criteria.
This nipple is suited for use in gas distribution lines, steam piping, compressed air systems, and hydronic heating systems. Its Schedule 40 wall thickness makes it appropriate for moderate-pressure applications in mechanical rooms, utility spaces, and inline pipe runs. Installers working on boiler connections, gas appliance supply lines, or general iron pipe assemblies will find this a straightforward drop-in threaded component.
Designed as an OEM-style replacement or new-installation component for 1-inch Schedule 40 iron pipe systems using standard NPT threaded fittings.
Installation should be performed by a licensed plumber or pipefitter in accordance with applicable codes including the International Fuel Gas Code or International Plumbing Code as required by the application. Shut off gas or fluid supply and depressurize the line before removing or installing any threaded pipe component. Apply an appropriate thread sealant or PTFE tape rated for the intended service medium before making up the connection. Do not over-tighten threaded joints; use a pipe wrench and backup wrench where needed to protect adjacent fittings.
