Asc Engineered Solutions 4354000450 Black Steel Nipple

Product Description

The ASC Engineered Solutions 4354000450 is a black steel seamless extra heavy (XH) pipe nipple sized at 1/4 inch x 3-1/2 inches. Built to ASTM A106B standards, this nipple provides a reliable threaded connection point in high-pressure or heavy-duty piping systems. The seamless construction eliminates weld seams, reducing potential leak paths under pressure. Licensed plumbers and pipefitters install this type of fitting in gas, steam, and industrial fluid distribution lines where standard-weight fittings are not adequate for the application.

This nipple is suited for commercial and industrial piping installations where extra heavy wall thickness is specified. Common applications include close-coupled connections in gas distribution headers, steam lines, and mechanical room piping assemblies. The 1/4 inch nominal pipe size makes it a go-to fitting for instrumentation takeoffs, gauge connections, and small-bore branch lines requiring robust, seamless construction.

Key Features

• Seamless extra heavy (XH) wall construction per ASTM A106B
• Black steel material for use in gas, steam, and industrial fluid service
• 1/4 inch x 3-1/2 inch nominal dimensions

Installation Notes

Installation should be performed by a licensed plumber or pipefitter in accordance with applicable codes, including the International Fuel Gas Code (IFGC) or International Plumbing Code (IPC) as relevant to the service. Shut off and depressurize the line completely before removing or installing any threaded nipple. Use appropriate pipe thread sealant or PTFE tape rated for the intended service medium. Inspect threads on both the nipple and mating fittings before makeup to avoid cross-threading.
