Legend Valve 404-396 2-1/2" X 2" SS304 Reducing Coupling

SKU CH-MM0G-Y18FS

304 stainless steel reducing coupling connects 2-1/2" to 2" FNPT threads for industrial plumbing systems

  • Reduces pipe size from 2-1/2" to 2" for flow transition
  • 304 stainless steel construction resists corrosion in demanding environments
  • FNPT x FNPT threads enable direct connection to female pipe fittings
  • Legend Valve 404-396 model ensures consistent manufacturing quality
  • California Proposition 65 warning indicates chemical hazard awareness required

Reducing Coupling 2-1/2" X 2

This reducing coupling joins a 2-1/2 inch female NPT thread to a 2 inch female NPT thread. It is made from 304 stainless steel for corrosion resistance in industrial plumbing systems. The fitting is supplied new and carries California Proposition 65 warnings for cancer and reproductive harm.

For Threaded Pipe Transitions

Suitable for installers who need to step down pipe size on a straight run using standard NPT threads. Not intended for systems that require welded or flanged connections instead of threaded joints. Buyers needing a different thread standard or a larger step-down ratio should look at other fittings.

304 Stainless Steel Material Grade

The coupling is manufactured from 304 grade stainless steel, which determines its chemical compatibility and temperature limits. Verify that the process fluid and operating conditions are within the envelope for this alloy before installation.

Questions about this item

Which size of the 404-396 reducing coupling matches my pipework?

The 404-396 is a 2-1/2" x 2" FNPT x FNPT fitting; choose it when you need to step down from a 2-1/2" female thread to a 2" female thread in the same line.

What does the 304 stainless steel construction mean once the coupling is installed?

304 stainless steel resists corrosion in water and many chemical lines, so the joint stays leak-free longer than plain steel in typical industrial plumbing service.

How does the FNPT thread standard affect what I can connect?

Both ends use FNPT taper threads, so the coupling accepts matching MNPT nipples or pipe ends; the taper seals on thread engagement, limiting the joint to the pressure rating of the connected schedule.
