Asc Engineered Solutions 8700139655 Black Iron Nipple

Product Description

The ASC Engineered Solutions 8700139655 is a 3/4-inch by 1-1/2-inch Schedule 40 black iron pipe nipple designed for use in standard plumbing, gas distribution, and mechanical piping systems. Constructed from welded steel with a black coating applied to resist corrosion, this nipple carries a standard NPT (National Pipe Thread) on both ends and meets ASTM A53 requirements for steel pipe. Licensed plumbers, pipefitters, and mechanical contractors use this fitting to make close or short connections between threaded components in low-pressure piping assemblies.

This nipple is suited for residential and light commercial applications including gas lines, water supply piping, compressed air lines, and steam systems where Schedule 40 wall thickness is required. The 3/4-inch nominal size is one of the most common sizes found in residential gas branch lines and mechanical room piping. It ships in minimum quantities of six, making it practical for service trucks and shop stock.

Key Features

• Welded steel construction meets ASTM A53 standards for structural and pressure service
• Black coating provides corrosion resistance for indoor piping and gas service applications
• Schedule 40 wall thickness suits standard pressure requirements in residential and commercial systems
• Standard NPT threads on both ends ensure compatibility with fittings, valves, and pipe couplings
• 3/4-inch nominal by 1-1/2-inch length for tight-clearance and close-nipple installations

Compatibility

Designed as an OEM-style replacement and standard stock fitting for use with 3/4-inch Schedule 40 threaded black iron piping systems in residential and commercial gas, water, and mechanical applications.

Installation Notes

Installation is performed by licensed plumbers or pipefitters in accordance with applicable local codes, IFGC requirements for gas systems, or IPC requirements for water systems. Apply an approved thread sealant or PTFE tape rated for the service medium before making up the joint. Hand-tighten first, then use a pipe wrench to achieve a proper thread engagement without over-torquing. Always shut off and depressurize the line before removing or installing any threaded fitting.
