The ASC Engineered Solutions 830509584 is a black steel extra heavy (XH) pipe nipple sized at 3/8 inch by 5-1/2 inches. It is a close-threaded fitting used to connect sections of pipe in gas, oil, or industrial piping systems. The extra heavy wall designation indicates a heavier wall thickness than standard schedule fittings, making it suitable for higher-pressure or higher-stress applications. Plumbers, pipefitters, and mechanical contractors install this type of nipple as a short pipe extension between threaded fittings, valves, or equipment connections.
This nipple is appropriate for use in residential and commercial plumbing and mechanical systems where black steel pipe is specified. Common applications include natural gas distribution lines, fuel oil supply piping, and general industrial piping assemblies. The 3/8 inch size fits standard 3/8 inch NPT threaded connections and is typically used in branch lines, appliance drops, or tight-space connections where a compact rigid section is needed between two threaded components.
Designed as an OEM-style replacement or standard component for black steel threaded piping systems using 3/8 inch NPT connections in gas, oil, or industrial mechanical applications.
Installation should be performed by a licensed plumber or pipefitter in accordance with applicable codes such as the IFGC or IPC. Shut off all gas or fluid supply and depressurize the line before removing or installing any threaded fitting. Apply an appropriate thread sealant or pipe tape rated for the intended service medium before making up the joint. Avoid over-tightening threaded connections, which can crack fittings or damage threads.
