The ASC ENGINEERED SOLUTIONS 4354004806 is a black steel seamless extra heavy (XH) pipe nipple designed for high-pressure and high-temperature piping systems. Manufactured from A106 carbon steel to seamless construction standards, this nipple measures 1-1/4 inches in diameter and 6 inches in length. Sold in a 10-piece run, it is a standard choice for plumbers, pipefitters, and mechanical contractors working on industrial, commercial, and heavy-duty residential piping installations where schedule 40 wall thickness is insufficient.
This nipple is suited for steam, gas, air, and fluid distribution systems that require robust, domestic-sourced pipe fittings. The extra heavy wall construction makes it appropriate for applications with elevated pressure ratings or demanding service conditions. Plumbers and pipefitters commonly use XH nipples in boiler rooms, mechanical rooms, and industrial process piping where connection integrity under load is critical. The 10-piece pack supports rough-in work and service jobs requiring multiple connections of the same size.
Designed as an OEM-style replacement or new-installation fitting compatible with 1-1/4 inch NPT threaded black steel piping systems in extra heavy service classifications.
Installation should be performed by a licensed plumber or pipefitter in accordance with applicable mechanical and plumbing codes, including IFGC and ASME B31 piping standards where required. Shut off and depressurize the system completely before removing or installing any threaded fittings. Use an appropriate pipe thread sealant or PTFE tape rated for the specific service medium — gas, steam, or liquid. Do not overtighten threaded connections; use a pipe wrench with controlled force to seat threads fully without cracking fittings.
