Legend Valve 416-375 1-1/4" X 1/4" SS316 Reducing Coupling equipment

SKU CH-303M-FYPZJ

Connects 1-1/4 inch and 1/4 inch FNPT threads using 316 stainless steel

  • Connects 1-1/4" to 1/4" pipes with FNPT threads
  • 316 stainless steel resists corrosion in harsh environments
  • Reducing coupling design enables smooth flow transition
  • Legend Valve brand delivers reliable industrial plumbing performance
  • New condition ensures full factory specification compliance

Product Identity

The Legend Valve 416-375 is a 316 stainless steel reducing coupling designed to join pipes of different diameters in industrial plumbing systems. It features female National Pipe Taper threads on both ends for a secure, leak-resistant connection. This new component meets the demands of corrosive fluid handling applications.

Suitable Applications

Installers working with chemical processing, marine environments or high-purity water systems will value the 316 alloy's resistance to pitting and crevice corrosion. The fitting is not intended for applications requiring a straight coupling between same-size pipes or for installations where a different thread standard or material grade is specified.

Critical Specification

The defining detail is the 1-1/4 inch by 1/4 inch FNPT x FNPT thread configuration, which dictates exactly which two pipe sizes this coupling joins. Verifying both thread diameters and the taper standard against your system drawing is the single step that confirms this is the correct part.

Highlights

  • Connects 1-1/4" to 1/4" pipes with FNPT threads
  • 316 stainless steel resists corrosion in harsh environments
  • Reducing coupling design enables smooth flow transition
  • Legend Valve brand delivers reliable industrial plumbing performance
  • New condition ensures full factory specification compliance

Questions about this item

What pipe sizes does the 1-1/4" x 1/4" reducing coupling connect?

It joins a 1-1/4 inch female NPT thread to a 1/4 inch female NPT thread.

How do I install this FNPT reducing coupling without damaging the 316 stainless threads?

Apply PTFE tape or pipe sealant to the male threads, hand-tighten, then finish with a wrench — avoid over-tightening which can gall stainless steel.

When should I replace this 316 stainless reducing coupling in a corrosive system?

Inspect regularly for thread galling, cracking or leakage; replace if visual inspection shows pitting, deformation or any seepage at the joint.
