The ASC Engineered Solutions 320200835 is a 3-inch taper tapped black steel half coupling designed for threaded pipe connections in gas, water, and industrial piping systems. The half coupling profile accepts a male-threaded pipe end on one side and is welded or threaded into place on the mating pipe or fitting. Black steel construction provides solid performance in standard-pressure, non-corrosive piping applications. At 1.60 pounds, the fitting is appropriately sized for field installation by licensed plumbers, pipefitters, and HVAC technicians working on ferrous pipe systems.
This half coupling is suited for residential and light commercial piping installations where a branch connection or end connection is needed on a black steel pipe run. Common applications include natural gas distribution lines, steam systems, and general industrial piping where NPT taper-tapped threads are the standard connection method. The fitting transitions a pipe end into a socket that can be incorporated into a larger assembly during rough-in or retrofit work.
Designed as an OEM-style replacement fitting for 3-inch black steel threaded piping systems using standard NPT taper-tapped connections.
Installation should be performed by a licensed plumber or pipefitter in accordance with local mechanical and plumbing codes, including IFGC requirements for gas piping systems. Shut off and depressurize the pipe system completely before threading or welding the coupling into position. Use appropriate pipe thread sealant or PTFE tape rated for the intended service medium when assembling threaded joints. Inspect threads for damage before installation to ensure a pressure-tight connection.
