Value Collection C543330G Malleable Iron Reducing Coupling

Product Description

The VALUE COLLECTION C543330G is a malleable iron reducing coupling designed to connect pipes of two different diameters in threaded piping systems. Rated at 300 psi for liquid and gas service and 150 psi for steam, this Class 150 fitting handles demanding mechanical and process piping environments. The galvanized finish provides corrosion resistance in exposed or moderately harsh conditions. It transitions from a 1-1/2-inch female thread to a 1-1/4-inch female thread, making it a standard choice for reducing branch connections in plumbing, HVAC, and industrial piping systems. Licensed plumbers and pipefitters install this type of fitting during new construction and retrofit work.

This reducing coupling is suited for residential and commercial applications where a threaded pipe run steps down in diameter. Common uses include water supply lines, natural gas distribution piping, steam heating systems, and compressed air lines. The Class 150 malleable iron construction meets standard requirements for most general-purpose pipe assemblies where welded or grooved fittings are not specified. It is sold in a package quantity of 5 pieces.

Key Features

• Reduces from 1-1/2-inch to 1-1/4-inch female NPT threads for in-line diameter transitions
• 300 psi liquid and gas pressure rating for high-demand service
• 150 psi steam pressure rating suitable for low-pressure steam heating systems
• Class 150 malleable iron construction for strength and thread integrity
• Galvanized finish for added corrosion resistance in exposed installations
• Sold in a package of 5 fittings to support multi-joint jobs

Compatibility

Designed as an OEM-style replacement or standard-fit component for threaded malleable iron piping systems using NPT connections in plumbing, gas, steam, and general mechanical piping applications.

Installation Notes

Installation is performed by licensed plumbers or pipefitters working under applicable plumbing and mechanical codes such as the IPC or IFGC. Shut off and depressurize the system completely before removing or installing any threaded fitting. Apply an appropriate thread sealant or PTFE tape to the male threads before assembly. Do not overtighten, as malleable iron threads can crack under excessive torque.
