Anvil 0300149804 Black Reducing Coupling 1.5x1.25 in Cast Iron

Product Description

The ANVIL 0300149804 is a black reducing coupling designed to connect pipe sections of two different diameters in pressurized piping systems. Constructed from cast iron with a black finish, this fitting transitions from a 1-1/2 inch female pipe thread (FPT) connection to a 1-1/4 inch FPT connection. It carries a Class 125 rating with a liquid and gas pressure rating of 125 psi, making it suitable for a range of plumbing, mechanical, and industrial piping applications. Licensed plumbers and pipefitters are the primary installers of this type of fitting.

This reducing coupling is used in residential and light commercial piping systems where a diameter reduction is required between two threaded pipe runs. Typical applications include water distribution, gas supply lines, and mechanical room piping where iron pipe is the specified material. The FPT end connections on both ends allow direct thread engagement with male-threaded pipe or fittings on each side of the transition.

Key Features

• Cast iron construction for durability in pressurized piping systems
• Black finish suitable for exposed and concealed iron pipe installations
• 125 psi pressure rating for liquid and gas service
• Female pipe thread (FPT) connections on both ends for standard threaded engagement
• Class 125 classification consistent with standard iron pipe fitting specs
• Compact dimensions: 2.25 inches length, 2.25 inches height, 2 inches width

Compatibility

Designed as an OEM-style replacement or new-install fitting for standard Class 125 threaded iron pipe systems using 1-1/2 inch to 1-1/4 inch diameter transitions.

Installation Notes

Installation should be performed by a licensed plumber or pipefitter in accordance with applicable codes such as the International Plumbing Code (IPC) or local authority requirements. Shut off and depressurize the line fully before removing any existing fittings or making new connections. Apply appropriate thread sealant or PTFE tape to male threads before engagement. Do not overtighten threaded iron fittings, as cast iron is not ductile and can crack under excessive torque.
