Value Collection C543330 Malleable Iron Reducing Coupling

Product Description

The VALUE COLLECTION C543330 is a malleable iron reducing coupling designed to connect pipes of two different diameters within the same run. It transitions from a 1-1/2 inch pipe to a 1-1/4 inch pipe and is rated for 300 psi on liquid and gas service and 150 psi on steam service. The galvanized finish provides corrosion resistance for use in a wide range of piping environments. This Class 150 threaded fitting is a standard component used by plumbers, pipefitters, and HVAC technicians in both new construction and retrofit applications.

This reducing coupling is suited for residential and light commercial piping systems carrying water, gas, air, or steam. It is commonly installed in supply and return lines where a pipe size reduction is required inline, without the use of a separate bushing. The threaded connection follows standard NPT pipe thread dimensions, making it compatible with other Class 150 malleable iron fittings in the same line.

Key Features

• Reduces from 1-1/2 inch to 1-1/4 inch in a single inline fitting
• 300 psi pressure rating for liquid and gas service
• 150 psi pressure rating for steam service
• Class 150 malleable iron construction for durability in threaded systems
• Galvanized finish for corrosion resistance
• Standard NPT threaded ends for compatibility with common pipe fittings

Compatibility

Designed as an OEM-style replacement or new-installation fitting for Class 150 threaded malleable iron piping systems using 1-1/2 inch and 1-1/4 inch NPT pipe.

Installation Notes

Installation should be performed by a licensed plumber or pipefitter in accordance with applicable local codes, including IPC and IFGC requirements for gas and plumbing systems. Shut off and depressurize the line completely before disassembling any fittings. Apply an approved thread sealant or PTFE tape to the male threads before assembly. Do not over-tighten threaded connections on malleable iron fittings, as this can crack the casting.
