Questions about this item

What does the 150 psi @ 450 °F rating mean for a live steam line?

The coupling is rated for 150 psi at 450 °F, so it will hold that pressure at typical saturated-steam temperatures without derating.

How does the FNPT connection and API 5L standard affect what pipe I can thread into it?

The female NPT threads accept 1-inch male NPT pipe, and API 5L confirms the steel is suitable for line-pipe service in oil, gas or water systems.

What clearance and support does the 1-inch Class 150 steel body need when I mount it?

Allow enough space for a 1-inch NPT wrench swing and support the adjacent pipe so the coupling carries no bending load.
