Asc Engineered Solutions 8700139903 Black Iron Nipple

Product Description

The ASC Engineered Solutions 8700139903 is a Schedule 40 black iron pipe nipple designed for threaded pipe assemblies in plumbing, gas distribution, and mechanical piping systems. Measuring 0.75 inches in diameter and 4 inches in length, it is constructed from welded steel with a black coating applied to inhibit rust formation. The standard NPT threads on both ends allow direct connection to fittings, valves, and other threaded pipe components. Licensed plumbers and pipefitters install this type of nipple in both residential and light commercial applications where a short, rigid threaded connection is required.

This nipple is suited for use in gas lines, steam systems, water distribution, and general industrial piping where Schedule 40 wall thickness and steel construction meet the project specification. The black coating distinguishes it from galvanized nipples and makes it a common choice for natural gas and propane piping where galvanized fittings are not recommended by code. It is sold individually and is compatible with standard 0.75-inch NPT fittings and pipe.

Key Features

• Schedule 40 wall thickness for standard-duty threaded piping applications
• Welded steel construction meets ASTM A53 standards
• Black coating applied to resist corrosion during storage and service
• Standard NPT threads on both ends for direct fitment to pipe fittings and valves
• 0.75-inch nominal diameter by 4-inch length for close-quarter connections

Compatibility

Designed as an OEM-style replacement or new-installation component for 0.75-inch Schedule 40 threaded steel pipe systems using standard NPT fittings.

Installation Notes

Installation is performed by licensed plumbers or pipefitters following applicable code requirements, including IFGC provisions for gas piping. Shut off and depressurize the line before removing or installing any threaded pipe component. Apply an appropriate pipe thread sealant or PTFE tape rated for the service medium before tightening. Do not overtighten threaded connections, as this can damage threads or cause misalignment in the assembly.
