Questions about this item

Which size and material version of the Legend Valve 416-167 locknut should I select for a 1-1/2 inch FNPT connection?

Choose the 1-1/2 inch 316 stainless steel FNPT locknut listed as model 416-167; it matches that exact thread size and material.

What does the 316 stainless steel designation mean for corrosion resistance once the locknut is installed?

Grade 316 stainless steel provides higher resistance to chlorides and acids than standard grades, extending service life in harsh water or chemical environments.

FNPT tapered threads create a mechanical seal when tightened, so the locknut secures the joint without requiring a separate gasket or sealant tape.
