Anvil 0320201825 Black Steel Coupling 1-1/2 in Class 300

Product Description

The ANVIL 0320201825 is a black-finish steel threaded coupling rated for Class 300 service at up to 300 psi. This fitting joins two threaded pipe segments of 1-1/2 inches nominal size, providing a secure, pressure-rated connection in piping systems handling liquid or gas. The steel construction and black finish make it suited for both above-ground and in-wall rough-in installations. Licensed plumbers, pipefitters, and mechanical contractors install this type of fitting as part of new construction or repair work on pressurized piping systems.

This coupling is used in residential and commercial piping applications where a straight, same-size threaded connection is required. Typical installations include gas distribution lines, water supply systems, and general mechanical piping where Class 300 pressure ratings are specified. The 1-1/2 inches size fits standard NPT-threaded pipe of the same nominal diameter.

Key Features

• Class 300 pressure rating supports up to 300 psi liquid and gas service
• Steel construction provides strength and durability in pressurized pipe systems
• Black finish suitable for gas and general mechanical piping applications
• Threaded end connections for standard NPT pipe assembly
• 1-1/2 inches nominal fitting size for direct same-size pipe joining

Compatibility

Designed as an OEM-style replacement or new-installation fitting for 1-1/2 inches NPT-threaded steel pipe systems rated to Class 300 service.

Installation Notes

Installation should be performed by a licensed plumber or pipefitter in accordance with applicable local codes and IFGC or IPC requirements. Depressurize and isolate the pipe section before cutting in or removing an existing fitting. Apply appropriate thread sealant or PTFE tape to male threads before assembly. Do not over-tighten; use a pipe wrench with a backup wrench on the adjoining fitting to avoid stress on downstream connections.
