4" Press Reducing Tee

The Legend Valve 450-334P is a 4" x 4" x 1" press reducing tee designed for plumbing installations. It connects two 4-inch runs with a 1-inch branch using a press-fit method. Professional installers and maintenance crews use it to create secure, leak-resistant junctions in commercial or residential piping systems.

Sustained System Pressure

The press connection creates a permanent mechanical seal that holds under continuous system pressure and thermal cycling. Unlike threaded joints that may loosen over time, the pressed joint resists vibration and movement without needing retightening. The fitting maintains integrity across the full operating range of the piping network it serves.

California Proposition 65 Notice

Questions about this item

Does the 450-334P tee generate noise, heat or draw power when the system runs all day?

This press reducing tee has no moving parts, electronics or power supply, so it produces no noise, no heat and consumes no power during continuous operation.

What pipe sizes and press tools must I already own for the 4" x 4" x 1" reducing tee to work?

You need 4 inch and 1 inch press-compatible piping plus a press tool and jaws rated for those diameters to make the connections.

Will the 450-334P tee connect reliably to older copper or steel pipe I plan to keep?

The tee is designed for press fittings; it will join older pipe only if that pipe is press-compatible and matches the 4 inch and 1 inch sizes.
