Questions about this item

How can I confirm the 3" galvanized union is sealing correctly after installation?

Pressurize the line and check the FNPT x FNPT joint for leaks; a dry thread seal indicates the union is working as intended.

What comes with the Legend Valve 352-450 union and what must I supply?

The box contains the 3" galvanized union only; you must provide pipe thread sealant or tape and the mating FNPT pipes.

Which version of the 352-450 should I choose for a 3" FNPT connection?

Select the 3" SA galvanized union listed as FNPT x FNPT; it matches a 3-inch female pipe thread on both ends.
