The ASC ENGINEERED SOLUTIONS 321200255 is a 1-inch taper tapped galvanized steel coupling designed for threaded pipe connections in plumbing, mechanical, and industrial piping systems. The taper-tapped thread design creates a secure, leak-resistant joint as the fitting draws tight against the pipe thread. Galvanized steel construction provides corrosion resistance in wet or exposed environments. This coupling is installed by licensed plumbers and pipefitters as part of standard threaded pipe assembly.
This fitting is suited for use in residential and commercial piping applications where galvanized steel threaded pipe is specified. Typical installations include water supply lines, drainage systems, and general mechanical piping where corrosion resistance and thread integrity are required. The 1-inch size accommodates standard 1-inch nominal pipe threading per common pipe thread standards.
Designed as an OEM-style replacement fitting for standard 1-inch nominal threaded galvanized steel pipe systems.
Installation is performed by licensed plumbers or pipefitters following applicable IPC and local plumbing code requirements. Shut off water supply and depressurize the line before removing or installing any threaded fittings. Apply appropriate thread sealant or PTFE tape to pipe threads before assembly to ensure a leak-free joint. Do not overtighten, as this can damage the taper threads or crack the fitting.
