The ASC ENGINEERED SOLUTIONS 4354000430 is a black steel seamless extra heavy (XH) pipe nipple sized at 1/4 inch by 2-1/2 inches. Manufactured to A106B standards, this nipple delivers the added wall thickness required in higher-pressure piping systems. It is used in threaded pipe assemblies where standard-weight fittings are insufficient. Plumbers, pipefitters, and mechanical contractors install this type of nipple in gas, steam, and industrial fluid systems where joint integrity and pressure tolerance are priorities. The black steel construction resists mechanical stress and suits applications where corrosion protection is handled downstream by system coatings or media compatibility.
This nipple fits into threaded 1/4-inch piping systems and is suited for commercial and light industrial installations. Extra heavy wall nipples are commonly used in steam distribution, compressed air headers, and gas supply branches where elevated pressures or mechanical strain exceed the limits of standard-weight pipe. The seamless construction eliminates weld seams, making it appropriate for applications where seam integrity is a concern. Import-sourced product meeting A106B specification requirements.
Designed as an OEM-style replacement or new-installation fitting for threaded 1/4-inch black steel piping systems requiring extra heavy wall nipples.
Installation should be performed by a licensed plumber or pipefitter in accordance with applicable mechanical and plumbing codes such as the IPC or IFGC. Shut off and depressurize the piping system completely before removing or installing any threaded fitting. Apply appropriate pipe thread sealant or PTFE tape to male threads before assembly. Do not overtighten threaded connections, as black steel fittings can crack if subjected to excessive torque.
