Anvil 0321201147 Steel Pipe Coupling 3/4 in 300 Psi

Product Description

The ANVIL 0321201147 is a 3/4-inch threaded steel pipe coupling designed for joining sections of pipe in liquid, gas, and steam service. Rated at 300 psi for both liquid and gas pressure and 300 psi for steam pressure, this Class 300 coupling meets the demands of industrial and commercial piping systems. The galvanized finish provides corrosion resistance in exposed or moderate-moisture environments. It uses National Pipe Straight (NPS) threading for a secure, leak-resistant connection. Licensed plumbers, pipefitters, and mechanical contractors install this fitting as part of new construction or retrofit piping runs.

This coupling is suited for residential and commercial applications where threaded steel pipe is used to convey liquids, gases, or steam. Typical install scenarios include hydronic heating systems, steam distribution lines, compressed air lines, and general industrial process piping. The 3/4-inch size fits common branch and main-line piping configurations across a wide range of commercial mechanical and industrial settings.

Key Features

• 300 psi liquid and gas pressure rating for demanding service conditions
• 300 psi steam pressure rating suitable for steam distribution piping
• NPS threaded end connections for standard pipe compatibility
• Galvanized steel finish for corrosion resistance
• Class 300 rating per API standards
• 3/4-inch fitting size for common pipe configurations

Compatibility

Designed as an OEM-style replacement or new-installation fitting for 3/4-inch NPS threaded steel pipe systems in liquid, gas, and steam service applications.

Installation Notes

Installation should be performed by a licensed plumber or pipefitter in accordance with applicable mechanical and plumbing codes, including IFGC and IPC requirements where applicable. Shut off and depressurize the pipe system completely before disassembling or installing any threaded fittings. Apply appropriate thread sealant or PTFE tape to NPS threads before making up connections. Do not overtighten threaded joints, as this can crack fittings or damage threads.
