Asc 8700136057 Black Iron Close Nipple 1/8 in Sch 40

Product Description

The ASC ENGINEERED SOLUTIONS 8700136057 is a close-pattern black iron pipe nipple manufactured from Schedule 40 welded steel. It measures 1/8 inch nominal pipe size and is cut to close length, meaning the threaded ends leave minimal unthreaded pipe between them. The black coating provides corrosion resistance for above-ground, dry-to-moderate-moisture installations. Standard NPT pipe threads on both ends allow direct connection to fittings, valves, and equipment across a wide range of piping systems. Licensed plumbers and pipefitters install this nipple as part of gas distribution, steam, and general fluid piping assemblies.

This close nipple is suited for residential and light commercial applications where a short, rigid connection between two threaded fittings is required. Typical uses include gas supply drops, heating system piping, compressed air distribution, and water service lines. It is commonly used alongside black iron fittings such as tees, elbows, and unions when assembling gas piping runs or steam heating manifolds. The 1/8 inch size is frequently seen in pilot gas supply lines and instrumentation connections.

Key Features

• Schedule 40 wall thickness for standard-pressure piping service
• Welded steel construction meets ASTM A53 specifications
• Black coated exterior to resist surface oxidation
• Close-pattern cut minimizes assembled length between fittings
• Standard NPT threads on both ends for broad fitting compatibility

Compatibility

Designed as an OEM-style replacement and standard stock nipple for 1/8 inch Schedule 40 black iron threaded piping systems.

Installation Notes

Installation should be performed by a licensed plumber or pipefitter in accordance with applicable local codes, the International Fuel Gas Code (IFGC), or the International Plumbing Code (IPC) depending on the service. Shut off and depressurize the line before disassembly or installation. Apply a code-approved thread sealant or PTFE tape rated for the intended service to all NPT connections before assembly. Do not use on systems or pressures exceeding the rating of the weakest connected component in the assembly.
