Asc Engineered Solutions 8700137055 Black Iron Nipple Sch 40

Product Description

The ASC Engineered Solutions 8700137055 is a Schedule 40 black iron pipe nipple used to join sections of threaded pipe in gas, steam, and water distribution systems. Made from welded steel with a black coating applied to resist corrosion, this nipple measures 0.25 inches in diameter and 4 inches in length. It features standard NPT threading on both ends for compatibility with standard pipe fittings. Plumbers, pipefitters, and gas line installers use this nipple in both residential and light commercial applications where a short, rigid threaded connection is required.

This nipple is suited for use in natural gas supply lines, steam systems, and water piping where Schedule 40 wall thickness is specified. The 0.25-inch diameter is commonly found in branch lines, appliance connections, and other low-flow distribution runs. The black coating distinguishes it from galvanized pipe, making it the correct choice for gas service where galvanized coatings are not permitted by code in many jurisdictions.

Key Features

• Schedule 40 wall thickness for standard-pressure pipe applications
• Black coating resists surface corrosion during storage and service
• Welded steel construction meets ASTM A53 standards
• Standard NPT threads on both ends for use with common pipe fittings
• 0.25-inch x 4-inch dimensions suit branch and appliance connection runs

Compatibility

Designed as an OEM-style replacement and standard stock fitting for Schedule 40 threaded steel pipe systems using 0.25-inch NPT connections.

Installation Notes

Installation should be performed by a licensed plumber or pipefitter in accordance with applicable local codes, including IFGC requirements for gas piping systems. Shut off the gas supply or isolate the water system before making any threaded connections. Apply a code-approved thread sealant or PTFE tape to the male threads before assembly. Do not use black iron pipe nipples on systems requiring galvanized or stainless fittings as specified by the design engineer or local authority.
