Legend Valve 404-381 1-1/2 x 3/8 SS304 Reducing Coupling

SKU CH-E60R-714ZV

Connects 1-1/2 inch and 3/8 inch pipes using 304 stainless steel FNPT threads

  • 304 stainless steel resists corrosion in demanding plumbing systems
  • Reducing design joins 1-1/2 inch to 3/8 inch FNPT threads
  • Female NPT on both ends simplifies installation without adapters
  • Legend Valve 404-381 model built for industrial-grade reliability
  • California Proposition 65 warning included for chemical safety awareness

Material & Size

This 304 stainless steel reducing coupling joins a 1-1/2 inch female NPT thread to a 3/8 inch female NPT thread. It is built for industrial piping systems that require a corrosion-resistant transition between two different pipe diameters.

Intended Use

Installers working with 304-grade stainless piping in water, oil or general chemical lines will find this fitting matches their material spec. Projects that require a different alloy, a straight coupling or a threaded-to-socket connection should look at other fittings.

Deciding Specification

The 304 stainless steel construction determines whether this coupling suits the fluid and environment in your system. Verify that 304 grade meets the corrosion and temperature requirements before purchasing.

Questions about this item

Does the 304 stainless steel coupling generate noise, heat or draw power during continuous flow?

The fitting is a passive 304 stainless steel component with no moving parts, so it produces no noise, no heat and consumes no power during all-day operation.

What piping must I already have to install this 1-1/2 x 3/8 reducing coupling?

You need a 1-1/2 inch FNPT threaded pipe and a 3/8 inch FNPT threaded pipe, plus suitable thread sealant for stainless steel connections.

Will this 304 stainless coupling work with older brass or carbon-steel fittings I keep in the system?

Yes, the FNPT threads mate with existing NPT components, though dissimilar metals should be isolated to prevent galvanic corrosion.
