The ASC Engineered Solutions 810086207 is a black malleable iron reducing coupling designed for threaded pipe connections in plumbing, HVAC, and industrial piping systems. This fitting reduces from a 3/4-inch female thread to a 3/8-inch female thread, allowing techs to transition between two common pipe sizes within a single fitting. The black oxide coating provides corrosion resistance suitable for gas and air distribution lines. At 0.20 pounds, this compact fitting is a standard component in threaded pipe assemblies used across residential and light commercial applications.
This reducing coupling is appropriate for use in natural gas distribution, compressed air, and general plumbing piping runs where a threaded reduction is required inline. It is installed by licensed plumbers, pipefitters, and HVAC technicians working with Schedule 40 black iron pipe systems. The fitting threads directly onto standard NPT-threaded pipe in both residential and commercial settings where black iron piping is the specified material.
Designed as an OEM-style replacement or new-installation fitting for standard NPT-threaded black iron pipe systems requiring an inline reduction from 3/4 inch to 3/8 inch.
Installation is performed by licensed plumbers or pipefitters working with black iron threaded pipe systems. Shut off and depressurize the line before removing or installing any threaded fitting. Apply an approved pipe thread sealant or PTFE tape to male threads before assembly and tighten to a snug fit using pipe wrenches. Follow all applicable local codes, including IPC and IFGC requirements, for pipe joint sealing and pressure testing after installation.
