The ASC Engineered Solutions 830006409 is a black steel pipe nipple measuring 0.25 inches in diameter by 4 inches in length. This close-cut threaded fitting connects sections of pipe in gas, air, and fluid distribution systems. Black steel pipe nipples are standard components in low-pressure gas piping, compressed air lines, and industrial plumbing assemblies. At 0.13 pounds, this nipple is a lightweight but durable threaded connector suited for use by licensed plumbers, pipefitters, and HVAC technicians working on ferrous pipe systems.
This nipple is appropriate for residential and light commercial applications where black steel pipe is the specified material. Common installation scenarios include natural gas supply lines, propane distribution piping, compressed air headers, and steam or hydronic heating systems. This is an import product, not domestic-manufactured. It is intended for use where black steel fittings are required by code or design specification.
Designed as a standard threaded replacement nipple for 0.25-inch black steel pipe systems in residential and commercial gas, air, and fluid piping applications.
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 and depressurize the line before removing or installing any threaded fitting. Apply appropriate thread sealant or PTFE tape rated for the service medium before making up the connection. Do not overtighten threaded joints, as this can crack fittings or damage threads.
