Asc Engineered Solutions 8700142303 Black Iron Nipple 1-1/4x4 in Sch

Product Description

The ASC Engineered Solutions 8700142303 is a Schedule 40 black iron pipe nipple used to join sections of threaded pipe in gas, steam, and water distribution systems. Manufactured from welded steel with a black coating applied to resist corrosion, this nipple measures 1-1/4 inches in diameter and 4 inches in length. It is threaded on both ends with standard NPT pipe thread, allowing direct connection to fittings, valves, and pipe sections of the same size. At 0.596 pounds, it is a compact, close-tolerance component suited for work in tight mechanical spaces. Installation is performed by licensed plumbers, pipefitters, and HVAC mechanics.

This nipple is appropriate for residential and light commercial plumbing, hydronic heating, gas distribution, and steam piping applications where Schedule 40 wall thickness is specified. The 1-1/4-inch diameter is a common size in main branch supply lines and boiler piping. It conforms to ASTM A53 standards, making it suitable for pressure-bearing installations where code-compliant materials are required.

Key Features

• Schedule 40 wall thickness for standard-pressure service
• Black coating provides corrosion resistance for above-ground and indoor applications
• Standard NPT threads on both ends for direct connection to compatible fittings
• Meets ASTM A53 specification for welded and seamless steel pipe
• Compact 4-inch length suits close-quarter piping configurations

Compatibility

Designed as an OEM-style replacement and standard-stock component for Schedule 40 threaded black iron piping systems using 1-1/4-inch NPT fittings, valves, and couplings.

Installation Notes

Installation should be performed by a licensed plumber or pipefitter in accordance with applicable local codes and the International Fuel Gas Code or International Plumbing Code as relevant to the service. Shut off and depressurize the line before removing or installing any threaded component. Apply an approved thread sealant or pipe-thread compound to NPT threads before assembly. Do not overtighten threaded connections, as this can crack cast fittings or distort threads.
