Reducing coupling for 2 in to 1-1/4 in FNPT pipe

This malleable iron reducing coupling joins a 2 inch female NPT thread to a 1-1/4 inch female NPT thread. It is rated Class 150 for standard pressure service. The ZORO SELECT fitting suits plumbing systems that require a step-down connection between two different pipe diameters. The part arrives new and ready for installation.

Verify thread standard

Confirm that both pipe ends use NPT threads with an 11 1/2 thread pitch. Ensure the system operating pressure stays within the Class 150 rating of this malleable iron body. Check that the 2 inch and 1-1/4 inch nominal sizes match the existing pipe schedule. The coupling is restricted from sale in certain states, so review local code compliance.

Replaces a straight coupling

Use this reducer instead of a straight coupling when the line transitions from 2 inch to 1-1/4 inch pipe. It eliminates the need for a separate bushing and nipple combination, saving space and potential leak paths. The jump is worth it whenever a direct, single-piece reduction simplifies the piping layout and meets the Class 150 requirement.

Questions about this item

Does the Value Brand Reducer Coupling 5P577 come with thread sealant or PTFE tape included?

The fitting is supplied alone; thread sealant or PTFE tape must be purchased separately to make a leak-free NPT joint.

Should I choose the 2 in x 1-1/4 in FNPT malleable iron Class 150 version or a different size for my pipe run?

Select this coupling only when you need to join a 2 in male NPT pipe to a 1-1/4 in male NPT pipe at a maximum working pressure of 150 psi.

What does the Class 150 rating mean once the reducer is installed in a real piping system?

Class 150 indicates the fitting is rated for 150 psi working pressure at ambient temperature with water or air.
