1-1/4" x 1-1/2" Press x FNPT Reducing Adapter

This Legend Valve adapter connects a 1-1/4 inch press fitting to a 1-1/2 inch female NPT thread. It serves plumbing professionals and maintenance teams who need to transition between different pipe sizes and connection types in a single fitting.

Press-to-thread transition

The defining specification is the Press x FNPT configuration. This combination allows a direct, tool-pressed joint on one end and a standard threaded connection on the other, eliminating the need for separate couplings and reducing potential leak paths.

Reducing flow capacity

The adapter handles the flow demands of the 1-1/4 inch press side while stepping up to the larger 1-1/2 inch thread. It runs out when system pressure or volume exceeds the rating of the press connection or the thread seal, requiring a larger-bodied fitting for higher loads.

Questions about this item

What does the 1-1/4x1-1/2 press-to-FNPT reduction mean for my piping layout?

It joins a 1-1/4 inch press connection to a 1-1/2 inch female NPT thread, letting you step pipe size without a separate coupling.

How does the press interface seal compared with threaded or soldered joints?

The press end uses a cold-press tool to form a permanent, leak-tight mechanical seal that is faster than threading and needs no flame.

What clearance and tool access does the 450-738P body need for installation?

The compact adapter body fits in tight stud bays and requires only enough room for the press jaws to close fully around the fitting.
