The ASC ENGINEERED SOLUTIONS 4354001630 is a black steel seamless extra heavy (XH) pipe nipple sized at 3/4 inch by 2-1/2 inches. Manufactured from black steel to ASTM A106B specifications, this close-tolerance seamless nipple delivers the wall thickness required for higher-pressure piping systems. The extra heavy schedule provides added durability in demanding mechanical, industrial, and commercial plumbing applications. Licensed plumbers and pipefitters install these nipples when standard-weight fittings are insufficient for the system's operating conditions.
This nipple is suited for use in commercial and industrial piping systems where black steel pipe is specified. Typical applications include gas distribution, steam lines, compressed air, and hydronic heating systems that require seamless construction and extra heavy wall thickness. At 3/4 inch by 2-1/2 inches, it fits standard pipe assemblies requiring a short, rigid threaded connection between fittings, valves, or equipment.
Designed as an OEM-style replacement or new-installation fitting for black steel threaded piping systems using 3/4 inch nominal pipe size components.
Installation should be performed by a licensed plumber or pipefitter in accordance with applicable codes such as the International Plumbing Code (IPC) or International Fuel Gas Code (IFGC). Shut off and depressurize the system completely before removing or installing any threaded fittings. Use an appropriate thread sealant or pipe tape rated for the service medium. Inspect threads carefully before assembly to ensure a leak-free joint.
