The ASC ENGINEERED SOLUTIONS 4354004802 is an 11-piece run of black steel seamless extra heavy (XH) pipe nipples sized at 3/4 inch by 6 inches. These nipples are manufactured to ASTM A106 seamless steel standards, making them suitable for high-pressure and high-temperature piping systems. The extra heavy wall construction provides greater pressure capacity compared to standard weight fittings. Licensed plumbers, pipefitters, and mechanical contractors install these nipples in industrial and commercial piping assemblies where durability and code compliance are required.
These black steel A106 seamless XH nipples are used in steam, gas, oil, and high-pressure water piping systems. The 3/4 inch by 6 inch size fits common branch and run configurations in commercial and industrial mechanical systems. The 11-piece run quantity suits rough-in work and larger piping jobs where multiple nipples of the same size are needed. Domestic origin makes these appropriate for projects with domestic material requirements.
Designed as OEM-style replacements for standard 3/4 inch threaded black steel piping systems using extra heavy seamless nipples in steam, gas, or high-pressure fluid service.
Installation should be performed by a licensed plumber or pipefitter in accordance with applicable mechanical and plumbing codes such as the IPC or IFGC. Isolate and depressurize the system completely before removing or installing any threaded fittings. Use appropriate pipe thread sealant or PTFE tape rated for the service fluid. Inspect threads on both the nipple and mating fitting before assembly to ensure a leak-free connection.
