The ASC Engineered Solutions 810090019 is a black malleable iron reducing coupling designed for threaded pipe connections where a reduction from 2.5-inch to 2-inch pipe is required. Finished with a black coating, this fitting is suited for low-pressure piping systems including gas distribution, water supply, and general-purpose industrial pipe runs. Malleable iron construction provides the ductility and thread-holding strength that trade installers require when making up mechanical joints in both new construction and retrofit work. Licensed plumbers, pipefitters, and HVAC mechanics are the typical installers for this class of fitting.
This reducing coupling is used in residential and light commercial piping applications where a 2.5-inch pipe must transition down to a 2-inch pipe along a threaded run. It is well suited for black iron gas piping, as well as general mechanical and industrial pipe systems that call for a standard threaded malleable iron fitting. The black coating is appropriate for above-ground and exposed installations where a uniform black-pipe appearance is required.
Designed as an OEM-style replacement and standard fitting for threaded black iron pipe systems requiring a 2.5-inch to 2-inch reducing coupling.
Installation should be performed by a licensed plumber or pipefitter in accordance with applicable mechanical and plumbing codes such as the IPC or IFGC. Shut off and depressurize the pipe system completely before removing or installing any threaded fittings. Apply an approved pipe thread sealant or PTFE tape to all male threads before make-up. Avoid over-torquing, which can crack malleable iron fittings, and always inspect threads for damage before assembly.
