Asc Engineered Solutions 810085019 Reducing Coupling 3/8x1/4

Product Description

The ASC ENGINEERED SOLUTIONS 810085019 is a black malleable iron reducing coupling designed for threaded pipe connections in plumbing, HVAC, and general mechanical piping systems. It transitions from a 3/8-inch female thread on one end to a 1/4-inch female thread on the other, allowing a step-down connection between two different pipe sizes. The black iron coating provides corrosion resistance suitable for gas lines, compressed air, and non-potable water distribution. Licensed plumbers and pipefitters are the primary installers. The fitting weighs 0.10 pounds, making it easy to handle in tight mechanical spaces.

This reducing coupling is used in residential and light commercial applications where threaded pipe systems require a size transition. Common installation scenarios include natural gas branch lines, propane distribution, compressed air piping, and steam or low-pressure fluid systems. It is installed inline between two threaded male pipe ends, using standard NPT threading conventions. The black finish distinguishes it from galvanized fittings and is standard practice for gas service piping per most local codes.

Key Features

• Malleable iron construction provides strength and resistance to cracking under mechanical stress
• Black coating suitable for gas, compressed air, and non-potable water service
• Reduces from 3/8-inch to 1/4-inch female threaded connections in a single fitting
• Lightweight at 0.10 pounds for easy single-hand installation
• NPT threaded ends for compatibility with standard threaded pipe systems

Compatibility

Designed as a standard NPT threaded reducing coupling for use in malleable iron pipe systems with 3/8-inch and 1/4-inch threaded components.

Installation Notes

Installation is performed by licensed plumbers or pipefitters following applicable codes such as the International Plumbing Code or local gas codes for fuel gas applications. Shut off gas supply or system pressure before installation and verify the line is depressurized before threading the fitting. Apply approved thread sealant or PTFE tape to the male threads before assembly. Do not over-tighten, as malleable iron fittings can crack under excessive torque.
