Industrial Plumbing Component

The Legend Valve 416-239 is a 2-1/2 inch hex plug manufactured from 316 stainless steel. It features female national pipe thread connections for integration into industrial piping systems. This new component suits maintenance engineers and facility managers specifying corrosion-resistant fittings for process lines.

Threaded Connection Limits

The FNPT interface relies on thread engagement and sealant to achieve a pressure-tight joint. Performance depends on correct assembly torque and the condition of the mating male threads. Installers must verify that the system pressure and media temperature remain within the design envelope of the 316 stainless steel material.

Upgrade From Carbon Steel

This plug replaces carbon steel or lower-grade alloy fittings where chemical compatibility or hygiene standards demand 316 stainless steel. The upgrade is justified when the process fluid attacks lesser alloys or when regulations require the higher alloy grade. It is not intended for applications requiring welded or flanged joint designs.

  • Corrosion-resistant piping with 316 stainless steel construction
  • Secure threaded sealing via FNPT female connection

Questions about this item

Should I choose the 2-1/2" 316 stainless hex plug or a different size for my piping?

The 416-239 model is a 2-1/2" FNPT plug made from 316 stainless steel; select it when your system requires that exact thread size and the corrosion resistance of 316 alloy.

What does the 316 stainless steel rating mean once the plug is installed in my system?

316 stainless steel gives the plug strong resistance to corrosion and chemical attack, helping it maintain a reliable seal in demanding water or fluid lines.

How does the FNPT thread standard affect what I can connect to this hex plug?

The FNPT (Female National Pipe Taper) threads accept a matching 2-1/2" male NPT fitting, creating a sealed joint when tightened with thread sealant or tape.
