The ASC Engineered Solutions 8700136354 is a Schedule 40 black iron pipe nipple used in threaded piping systems across residential and commercial applications. Manufactured from welded steel with a black coating to resist rust, this nipple measures 1/8 inch nominal diameter and 4 inches in length. It features standard NPT threads on both ends for secure, leak-resistant connections. Licensed plumbers, pipefitters, and HVAC technicians rely on nipples like this to extend, offset, or connect threaded pipe runs in gas, steam, and water distribution systems. The part meets ASTM A53 standards for welded steel pipe.
This nipple is suited for use in low-pressure gas lines, water supply systems, steam distribution, and general industrial piping. It is a common component in residential gas appliance hookups, boiler rooms, and mechanical rooms where 1/8 inch threaded connections are required. The black iron finish makes it appropriate for natural gas and propane supply lines where corrosion resistance is needed in dry environments.
Designed as an OEM-style replacement and general-use component for Schedule 40 threaded black iron piping systems using 1/8 inch nominal pipe size fittings.
Installation should be performed by a licensed plumber, pipefitter, or qualified HVAC technician in accordance with applicable local codes, IFGC, and IPC requirements. Shut off and depressurize the piping system completely before removing or installing threaded nipples. Apply an approved pipe thread sealant or PTFE tape rated for the intended service medium before threading the nipple into fittings. Do not over-tighten threaded connections, as this can crack fittings or damage threads.
