Stainless steel reducing coupling with female threads

Legend Valve

Legend Valve 416-377 1-1/4" x 1/2" 316 SS Reducing Coupling

SKU CH-5VFY-0GAPB

A 316 stainless steel reducing coupling joins 1-1/4 inch and 1/2 inch FNPT threads

  • 316 stainless steel resists corrosion in harsh environments
  • Reducing design joins 1-1/4" and 1/2" FNPT threads
  • Female NPT ends allow direct pipe connection
  • New condition ensures clean, undamaged threads
  • Prop 65 warning discloses regulated chemical content

Reducing Coupling 1-1/4" x 1/2

The Legend Valve 416-377 is a 316 stainless steel reducing coupling with FNPT threads on both ends. It connects a 1-1/4 inch female pipe thread to a 1/2 inch female pipe thread in industrial plumbing systems. The fitting is supplied new and carries a California Proposition 65 warning for chemicals known to cause cancer and reproductive harm.

Installers joining dissimilar pipe sizes

This coupling suits technicians who must transition between the two stated thread sizes using a corrosion-resistant 316 stainless alloy. It is not for systems requiring a male-threaded connection, a straight coupling of identical diameters, or a material grade other than 316 stainless steel. Buyers needing a different reduction ratio or thread standard should select another fitting.

316 stainless steel construction

The single specification that decides fitment is the 316 stainless steel body, which determines chemical compatibility and corrosion resistance in the target application. Verify that the process media and environment are suitable for this alloy before installation. The FNPT thread form on both ports must also match the existing piping.

Questions about this item

What is the first limit that appears when this reducing coupling is under sustained pressure?

The 316 stainless steel body resists corrosion and maintains its seal continuously, so no early fatigue limit is reached under normal service.

How much heat or noise does this coupling generate when installed in a system running all day?

As a passive 316 stainless steel fitting it produces no heat and no noise during continuous operation.

What existing pipe threads must I already have for this 416-377 coupling to connect directly?

You need a 1-1/4 inch FNPT thread on one side and a 1/2 inch FNPT thread on the other for a direct fit.
