Legend Valve 416-391 Reducing Coupling

This Legend Valve 416-391 reducing coupling joins 2 inch and 1-1/4 inch FNPT threads in industrial piping systems. The 316 stainless steel construction provides corrosion resistance for chemical and process lines. It carries a 150 pressure rating for standard service conditions. The component is supplied new from the manufacturer.

Suitable for chemical and process piping

Installers handling corrosive fluids or high-purity requirements will find the 316 alloy appropriate. Buyers needing a different thread size, a higher pressure class, or a non-metallic coupling should select another fitting. The Proposition 65 notice indicates the presence of listed chemicals.

316 stainless steel alloy

The 316 stainless steel material determines suitability for aggressive media where 316 is specified. Verify the alloy requirement against the fluid compatibility chart for the application. The 150 pressure rating and FNPT thread form are the other fixed parameters.

150 pressure rating

This coupling is rated for 150 service pressure in the line size shown. Systems operating above this limit require a higher-class fitting. Confirm the design pressure before installation.

Questions about this item

Will the 316 stainless steel reducing coupling connect to my existing 150-rated piping without galvanic issues?

The 316 stainless steel body matches the 150 pressure class and resists corrosion when joined to similar alloy pipe, so it integrates with existing 150-rated stainless systems without creating a galvanic cell.

How can I verify the 416-391 coupling is seated and leak-free after threading it onto FNPT ends?

Pressurise the line to the 150 rating and inspect both FNPT joints; no weep or pressure drop confirms the 316 stainless threads are fully engaged and sealed.

Does the box contain thread sealant or gaskets for the 2 in x 1-1/4 in FNPT connection, or must I buy them separately?

Only the 316 stainless reducing coupling is supplied; thread sealant or PTFE tape for the FNPT joints must be purchased separately.
