Asc Engineered Solutions 8700139705 Black Iron Nipple

Product Description

The ASC Engineered Solutions 8700139705 is a black iron pipe nipple designed for use in threaded pipe assemblies across plumbing, gas distribution, and mechanical piping systems. Measuring 3/4 inches in diameter and 2 inches in length, this Schedule 40 nipple is manufactured from welded steel with a black coating applied to inhibit corrosion. It features standard NPT pipe threads on both ends, allowing it to connect directly to fittings, valves, and other threaded pipe components. Licensed plumbers, pipefitters, and HVAC mechanics typically install this fitting in new construction and retrofit applications alike.

This nipple is suited for residential and light commercial gas supply lines, steam and hot water heating systems, fire suppression piping, and general plumbing distribution lines. The 3/4-inch diameter is a common size in branch and main supply runs. The 2-inch close length makes it useful in tight spaces where a longer nipple would not fit. It meets ASTM A53 standards, confirming material and weld integrity appropriate for pressure-bearing applications.

Key Features

• Schedule 40 wall thickness rated for standard working pressures in threaded steel pipe systems
• Black coating provides corrosion resistance during storage and service in dry or low-moisture environments
• Welded steel construction meets ASTM A53 material and weld quality standards
• Standard NPT threads on both ends for compatibility with threaded fittings, valves, and couplings
• 3/4-inch diameter and 2-inch length suit close-clearance installations in branch piping runs

Compatibility

Designed as an OEM-style replacement or new-installation component for Schedule 40 threaded steel piping systems using standard 3/4-inch NPT fittings and couplings.

Installation Notes

Installation should be performed by a licensed plumber or pipefitter in accordance with applicable local codes and the International Fuel Gas Code or International Plumbing Code as appropriate. Shut off the gas or water supply and depressurize the line before beginning work. Apply an approved thread sealant or PTFE tape rated for the service fluid before threading the nipple into fittings. Do not over-torque threaded connections, as this can crack cast fittings or damage threads.
