The ASC ENGINEERED SOLUTIONS 320200199 is a 2-inch taper tapped black steel coupling designed for threaded pipe connections in commercial and residential piping systems. The taper-tapped configuration provides a secure, pressure-rated threaded engagement that resists loosening under vibration and thermal cycling. Constructed from black steel, this coupling suits gas distribution, fire suppression, and general industrial piping where galvanized or stainless material is not required. At 1.11 pounds, it is a solid, full-weight forged fitting appropriate for permanent installation. Plumbers, pipefitters, and mechanical contractors work with this type of fitting routinely on black iron pipe assemblies.
This coupling is intended for use in threaded black iron pipe systems, typically in natural gas supply lines, propane distribution, steam, and low-pressure industrial fluid applications. It is well suited for both new construction rough-in and retrofit work where a standard 2-inch taper thread connection is needed to join two pipe sections or transition to an adjacent fitting. Installation typically follows IFGC or IPC guidelines depending on the media being conveyed.
Designed as an OEM-style replacement and standard-fit coupling for 2-inch threaded black iron pipe systems.
Installation should be performed by a licensed plumber or pipefitter following applicable IFGC or IPC code requirements for the media being conveyed. Shut off and depressurize the pipe system fully before disassembling any existing fittings. Apply an approved thread sealant or PTFE tape rated for the service media to all male threads before assembly. Do not over-tighten with pipe wrenches, as black steel threads can be damaged by excessive torque beyond hand-tight plus the standard number of engaged turns per fitting type.
