Questions about this item

What is included with the 416-402 reducing coupling and do I need to buy sealant or tape separately?

The box contains the 316 stainless steel reducing coupling with FNPT threads on both ends. Thread sealant or PTFE tape is not included and must be purchased separately for a leak-free joint.

How do I choose between the available versions of this Legend Valve fitting?

The 416-402 is a single configuration: a 4-inch by 2-inch reducing coupling in 316 stainless steel with female NPT threads. No alternative sizes, materials or thread types are offered under this model number.

What does the 316 stainless steel designation mean for corrosion resistance once the coupling is installed in a piping system?

Grade 316 stainless steel provides enhanced resistance to chlorides, acids and marine atmospheres compared with lower alloy grades, reducing the risk of pitting and stress-corrosion cracking in aggressive water or chemical service.
