The ASC ENGINEERED SOLUTIONS 320200249 is a 3-inch black steel taper tapped coupling designed for threaded pipe connections in gas, oil, and industrial piping systems. The taper-tapped design accepts standard tapered NPT threads, creating a pressure-rated mechanical joint without additional sealant compounds when used with proper thread tape or pipe dope. Weighing 3.36 pounds, this coupling is built for demanding service conditions where a durable ferrous fitting is required. It is installed by licensed plumbers, pipefitters, and HVAC technicians working on black iron pipe runs in both residential and commercial applications.
This coupling is suited for use in natural gas distribution lines, fuel oil piping, and general industrial fluid conveyance where black steel fittings meet code requirements. The taper tapped threads conform to standard NPT specifications, making this fitting compatible with Schedule 40 black iron pipe and other standard-thread pipe systems. It is a common choice on new construction and retrofit piping projects where a reliable threaded mechanical joint is needed at a 3-inch diameter transition or union point.
Designed as an OEM-style replacement and standard fitting for 3-inch black iron threaded pipe systems using NPT connections in gas, oil, and industrial piping applications.
Installation should be performed by a licensed plumber or pipefitter in accordance with applicable codes such as the IFGC or ASME B31 piping standards. Shut off and bleed the gas or fluid supply completely before disconnecting or installing any threaded fitting. Apply approved thread sealant tape or pipe dope to male NPT threads before assembly. Do not overtighten or use pipe wrenches in a manner that could crack or distort the coupling body.
