Value Collection C543322 Malleable Iron Reducing Coupling

Product Description

The VALUE COLLECTION C543322 is a malleable iron reducing coupling designed to connect pipes of two different diameters in plumbing, HVAC, and industrial piping systems. Sized at 1-1/4 inches by 3/4 inches, this Class 150 fitting carries a pressure rating of 300 psi for liquid and gas service and 150 psi for steam service. The galvanized finish provides corrosion resistance suited to a range of wet and dry environments. Licensed plumbers and pipefitters install this type of fitting in both new construction and retrofit applications where a step-down connection between nominal pipe sizes is required.

This reducing coupling is suited for residential and light commercial piping runs carrying water, gas, air, or steam within rated pressure limits. It threads onto standard NPT pipe and is a common solution when transitioning between 1-1/4 inch and 3/4 inch pipe runs in supply, distribution, or process lines. The Class 150 designation aligns with standard malleable iron fitting specifications used across the plumbing and mechanical trades. Package quantity is 5 units per order.

Installation Notes

Installation is performed by a licensed plumber or pipefitter in accordance with applicable IPC and IFGC code requirements. Shut off and depressurize the pipe system completely before removing any existing fittings or threading new connections. Apply appropriate thread sealant or PTFE tape to male threads before making up the joint. Do not exceed the rated pressure limits for the service type in use.
