Asc Engineered Solutions 8700143301 Black Iron Nipple

Product Description

The ASC Engineered Solutions 8700143301 is a black iron close nipple designed for use in threaded pipe assemblies across plumbing, HVAC, gas, and industrial piping systems. Manufactured from welded steel with a black oxide coating, this nipple measures 1-1/2 inches in diameter and 2 inches in length and conforms to Schedule 40 wall thickness. It carries standard NPT pipe threads on both ends for secure, leak-resistant connections. At 0.338 pounds, it is a compact, durable fitting suited for professional installations requiring reliable ferrous pipe work.

This nipple is used in residential and commercial piping systems where black iron fittings are required. Common applications include natural gas supply lines, steam systems, fire suppression headers, and general-purpose fluid handling. The 1-1/2 inch by 2 inch size fits into tight-space transitions and riser assemblies. Licensed plumbers, pipefitters, and HVAC technicians routinely install this type of nipple when assembling or extending threaded pipe runs.

Installation Notes

Installation should be performed by a licensed plumber or pipefitter in accordance with applicable IPC or IFGC code requirements. Shut off gas or fluid supply and depressurize the line before removing or installing any threaded fittings. Apply an approved thread sealant or PTFE tape rated for the service medium before making up the joint. Do not over-tighten; hand-tight plus wrench turns per fitting manufacturer guidance is standard practice.
