Anvil 0320201759 Black Steel Threaded Coupling 1/8 in

Product Description

The ANVIL 0320201759 is a black steel threaded coupling designed for joining two sections of pipe in gas and liquid piping systems. Built to Class 300 specifications with a 300 psi pressure rating, this fitting handles demanding service conditions in commercial and industrial applications. The black finish indicates a standard carbon steel fitting without galvanization, commonly used in gas piping, mechanical rooms, and process systems. At 1/8 inch fitting size with NPS threads, it is a small-diameter fitting typically installed by licensed plumbers, pipefitters, and HVAC mechanics where compact, high-integrity connections are required.

This coupling is suited for use in low-pressure and moderate-pressure gas distribution piping, hydronic heating systems, compressed air lines, and general industrial fluid systems where steel fittings are required. The 1/8 inch size is frequently used for pilot lines, instrument connections, drain taps, and small branch connections. The threaded end connections follow NPS thread standards, making this fitting compatible with standard pipe threads found across North American piping infrastructure.

Key Features

• Class 300 rated with a 300 psi liquid and gas pressure rating
• Steel construction with black finish for standard carbon steel service
• Threaded end connections with NPS thread standard
• 1/8 inch fitting size for small-diameter pipe connections
• Coupling configuration joins two pipe ends in a straight run

Compatibility

Designed as an OEM-style replacement or service fitting for standard 1/8 inch NPS threaded steel piping systems in gas, liquid, and compressed air service.

Installation Notes

Installation should be performed by a licensed plumber or pipefitter in accordance with applicable codes, including IFGC and ASME B31 standards where relevant. Shut off and depressurize the piping system completely before removing or installing any threaded fitting. Apply appropriate thread sealant or PTFE tape rated for the intended service medium before making up the connection. Do not overtighten threaded fittings, as this can crack the fitting or damage threads.
