316 stainless steel reducing coupling with tapered threads

Legend Valve

Legend Valve 416-395 2-1/2" x 1-1/2" 316 Stainless Steel Reducing Coupling

SKU CH-S9PY-1VB2E

Connects 2-1/2" to 1-1/2" FNPT pipes using corrosion-resistant 316 stainless steel

  • 316 stainless steel resists corrosion in harsh fluid systems
  • Reducing design joins 2-1/2 inch and 1-1/2 inch FNPT threads directly
  • Female NPT threads on both ends simplify installation without extra adapters
  • Legend Valve manufacturing ensures consistent thread quality and pressure integrity
  • New condition guarantees full material certification and clean internal surfaces

Legend Valve 416-395 Reducing Coupling

The Legend Valve 416-395 is a 316 stainless steel reducing coupling designed for industrial plumbing systems. It connects pipes with different diameters using female NPT threads on both ends. This new component suits engineers and maintenance crews who need a reliable transition fitting.

Build Quality and Threaded Connections

The coupling uses 316 stainless steel for corrosion resistance in demanding fluid-handling environments. Its FNPT x FNPT threaded design allows direct installation onto male-threaded pipe or nipples without welding. The tapered threads create a mechanical seal that can be tightened on site with standard pipe wrenches.

Pressure Rating and Chemical Exposure Limits

The product carries California Proposition 65 warnings for chemicals known to cause cancer and reproductive harm. Installers must verify that the coupling's pressure class matches the system design and that the 316 alloy is compatible with the specific media. These regulatory and material constraints define the practical boundaries for safe deployment.

Questions about this item

Does the FNPT x FNPT thread standard limit the coupling to tapered pipe threads only?

Yes, FNPT means female national pipe taper threads on both ends, so it seals with matching male NPT fittings and is not compatible with straight-thread or metric connections.

What pipe diameters must the installer have on hand for the 2-1/2" x 1-1/2" reducing coupling?

One pipe with 2-1/2 inch NPT male threads and another with 1-1/2 inch NPT male threads; the coupling reduces directly between those two sizes.

What is the correct sealing method when installing this 316 stainless steel reducing coupling?

Apply PTFE tape or pipe-thread sealant to the male threads only, tighten hand-tight plus one to two full turns with a wrench, and avoid over-torquing which can crack the female ports.
