Asc Engineered Solutions 8700136255 Black Iron Nipple 1/8x3 in Sch 40

Product Description

The ASC Engineered Solutions 8700136255 is a black iron close nipple designed for threaded pipe assemblies in plumbing, gas distribution, and mechanical piping systems. Manufactured from welded steel with a black coating applied to resist corrosion, this nipple measures 1/8 inch nominal pipe size at 3 inches in length and is produced to Schedule 40 wall thickness. Standard NPT threads on both ends allow direct connection to fittings, valves, and other threaded components. Licensed plumbers and pipefitters install this type of nipple when extending or connecting threaded iron pipe runs in residential and light commercial applications.

This nipple is suited for low-pressure gas lines, steam, air, and water service in residential and commercial mechanical systems. It is commonly used in boiler rooms, utility connections, and gas appliance rough-ins where Schedule 40 black iron pipe is the specified material. The 1/8 inch size is typical for pilot gas lines, instrumentation taps, and small-diameter branch connections. Installation follows standard NPT fitting practices.

Key Features

• Black-coated welded steel construction resists corrosion in dry and low-humidity environments
• Schedule 40 wall thickness meets standard pressure ratings for threaded iron pipe systems
• Manufactured to ASTM A53 standards for structural and pressure service
• Standard NPT threads on both ends for direct connection to compatible fittings and valves
• 1/8 inch nominal pipe size suits pilot gas lines, instrumentation ports, and small-diameter branch runs

Compatibility

Designed as an OEM-style replacement and standard component for Schedule 40 threaded black iron pipe systems using 1/8 inch NPT fittings and connections.

Installation Notes

Installation is performed by a licensed plumber or pipefitter in accordance with applicable local codes, the International Plumbing Code, or the International Fuel Gas Code where gas service is involved. Shut off all gas or water supply and depressurize the line before removing or installing any threaded nipple. Apply an approved thread sealant or PTFE tape rated for the intended service medium to all NPT connections. Do not over-tighten threaded connections; use a pipe wrench with appropriate leverage for the fitting size.
