Product Identity

The Legend Valve 404-400 is a 304 stainless steel reducing coupling with 3 inch by 2 inch FNPT threads. It joins pipes of different diameters in industrial plumbing systems where corrosion resistance matters.

Thermals Noise Power

This coupling has no moving parts, electrical draw or active cooling so it produces no noise and adds no heat to the system. Pressure rating and temperature limits depend on the piping schedule and media used.

Accessories Software

The coupling ships as a single fitting with no gaskets, sealant or software included. Installers must supply thread sealant or tape compatible with the service fluid and local code requirements.

Questions about this item

How do I install the 3" x 2" SS304 reducing coupling and what step is often missed?

Apply thread sealant to the FNPT threads, hand-tighten both ends, then use a wrench for one to two extra turns; the step often missed is skipping the sealant, which causes leaks.

What maintenance or replacement will the 304 stainless steel reducing coupling need later?

Inspect the FNPT threads and sealing surfaces periodically for corrosion or mineral build-up; replace the coupling if thread damage or persistent leaks appear.

What limit shows up first on the 3" x 2" reducing coupling under sustained pressure and temperature cycles?

The FNPT thread seal is the first limit; repeated thermal expansion and pressure spikes can degrade the sealant and cause weeping at the joint.
