The ASC ENGINEERED SOLUTIONS 4354000410 is a black steel seamless extra heavy (XH) pipe nipple sized at 1/4 inch by 1-1/2 inches. Manufactured to ASTM A106 Grade B standards, it delivers the wall thickness and pressure rating required in demanding piping applications. The seamless construction eliminates weld seams, producing a uniform pipe body that resists failure under high pressure and thermal stress. Plumbers, pipefitters, and mechanical contractors install this nipple where standard-wall fittings are insufficient and a heavier schedule is required by code or system design.
This nipple is suited for use in industrial, commercial, and non-domestic piping systems. Its 1/4 inch nominal size makes it appropriate for branch connections, instrumentation taps, and small-bore piping runs where black steel is specified. The extra heavy wall schedule supports applications involving elevated pressures or temperatures beyond the range of standard Schedule 40 fittings. It is not rated for domestic potable water service.
Designed as a standard-thread replacement or new-installation nipple for 1/4 inch NPT black steel piping systems in commercial and industrial applications where extra heavy wall schedule is required.
Installation should be performed by a licensed plumber or pipefitter in accordance with applicable mechanical and plumbing codes, including ASME B31 piping standards where required. Shut off and depressurize the piping system fully before removing or installing any threaded fitting. Apply an appropriate pipe thread sealant or PTFE tape rated for the service fluid. Do not overtighten threaded connections, as black steel NPT threads can crack fittings or distort threads under excessive torque.
