The ASC Engineered Solutions 830500385 is a black steel extra heavy (XH) pipe nipple sized at 1/8 inch by 5-1/2 inches. Pipe nipples are short threaded sections used to connect two female-threaded fittings, extend a pipe run, or create an offset in a piping assembly. This fitting is manufactured from black steel, making it well suited for gas distribution, steam, and industrial fluid systems where a coated or galvanized finish is not required. Licensed plumbers, pipefitters, and HVAC technicians are the primary installers of this type of fitting in both commercial and residential applications.
The extra heavy wall designation provides additional pressure capacity compared to standard schedule fittings, making this nipple appropriate for higher-pressure gas or steam service runs. At 1/8 inch nominal pipe size and 5-1/2 inches in length, it fits tight-clearance locations where a close or short nipple would not provide enough thread engagement or reach. Common uses include gas appliance connections, boiler piping assemblies, and industrial process lines requiring a small-diameter threaded connector.
Designed as an OEM-style replacement or new-installation fitting for small-diameter black steel threaded piping systems requiring a 1/8 inch NPT extra heavy nipple.
Installation should be performed by a licensed plumber, pipefitter, or qualified HVAC technician in accordance with applicable local codes, including IFGC and IPC requirements for piping materials and joints. Shut off and depressurize the gas or fluid system fully before removing any existing fittings or installing this nipple. Apply an appropriate thread sealant or PTFE tape rated for the intended service medium to both threaded ends before makeup. Do not over-torque threaded connections on small-diameter fittings, as this can crack adjacent fittings or distort threads.
