Anvil 0320201783 Black Steel Coupling 1/2 in Class 300

Product Description

The ANVIL 0320201783 is a black-finish steel threaded coupling designed for joining sections of pipe in gas and liquid distribution systems. Rated at Class 300, this fitting handles pressure up to 300 psi and is threaded to NPS standards for consistent fitment with standard pipe. The black finish indicates a plain, non-galvanized steel construction suited for gas piping, oil lines, and similar applications. At 0.24 pounds, it is a compact, single-unit fitting intended for installation by licensed plumbers, pipefitters, and HVAC technicians working on low- to medium-pressure systems.

This coupling is used in residential and commercial piping applications where a straight, in-line connection between two threaded pipe ends is required. Typical installation scenarios include natural gas supply lines, steam systems, hydraulic lines, and general industrial piping. The 1/2-inch size is common in branch supply and service lines. It is sold individually and carries no minimum order beyond a single unit.

Installation Notes

Installation should be performed by a licensed plumber or pipefitter in accordance with applicable codes such as the IPC or IFGC. Shut off and depressurize the supply line completely before threading or unthreading any fittings. Apply an approved thread sealant or PTFE tape to male threads before assembly. Do not over-tighten threaded connections, as this can crack or deform the fitting body.
