Reducing coupling for press systems

The Legend Valve 450-431P is a 1-1/2x1 reducing coupling designed to join pipes of different diameters in a press-style installation. It suits plumbers and contractors who need a permanent, tool-set connection without threading or soldering on the job site.

Press-interface constraints

The fitting relies on a compatible press tool and jaw set to form the mechanical seal; it cannot be installed with hand tools alone. California Proposition 65 notices indicate the product contains a chemical known to the state to cause cancer and birth defects or other reproductive harm, so appropriate handling precautions apply.

Flow capacity and headroom

The coupling reduces from a larger to a smaller bore, so maximum flow is limited by the smaller pipe size and any upstream restrictions. It handles typical residential and light-commercial water distribution pressures, but high-pressure or high-temperature service beyond standard plumbing ratings would require a different fitting class.

Questions about this item

Which size of the 450-431P reducing coupling do I need?

The 450-431P is a 1-1/2" x 1" fitting-by-press reducing coupling, so choose it when you must join a 1-1/2 inch fitting end to a 1 inch press connection.

How does the 1-1/2" x 1" fitting-by-press connection work once installed?

One end slides over a 1-1/2 inch fitting and the other accepts a 1 inch tube for press-tool crimping, creating a permanent, leak-tight joint without solder or thread sealant.

What does the press interface cap in practice?

The press end requires a compatible press tool and jaws sized for 1 inch tubing; it cannot be used with push-fit, compression or threaded connections.
