The ASC Engineered Solutions 810087007 is a black malleable iron reducing coupling designed to connect a 1-inch pipe to a 1/2-inch pipe in threaded piping systems. The black oxide coating provides corrosion resistance suitable for gas, air, and other common pipe applications. Malleable iron construction gives the fitting the toughness and ductility needed to handle installation torque and system vibration. This fitting is installed by licensed plumbers, pipefitters, and HVAC technicians working on low-pressure gas or mechanical piping systems.
This reducing coupling is commonly used in residential and light commercial piping installations where a threaded line size reduction is required inline. Typical applications include natural gas distribution piping, compressed air lines, and water systems where black iron fittings are specified. The 1-inch by 1/2-inch configuration addresses common branch or drop scenarios in supply piping layouts.
Designed as an OEM-style replacement or new-installation fitting for standard NPT threaded black iron piping systems.
Installation is performed by a licensed plumber or pipefitter following applicable IPC or IFGC code requirements for the system type. Shut off and depressurize the pipe system completely before removing or installing any threaded fittings. Apply an approved thread sealant or PTFE tape to male threads before assembly. Do not over-torque the fitting, as malleable iron can crack if excessive force is applied.
