Questions about this item

How can I confirm the hex bushing is sealing correctly after installation?

Pressurise the line up to the 300 psi rating at 150 °F and check for leaks at the male and female NPT threads.

What comes in the package and what additional parts are required?

The box contains the Class 150 malleable iron hex bushing only; pipe sealant or tape and Schedule 40 pipe must be purchased separately.

Which version of this fitting should I select for a 1-inch male to 1/4-inch female NPT connection?

Choose the single listed model 0318906849, which provides exactly that 1 in male by 1/4 in female NPT reduction.
