Questions about this item

What does the 500 psi @ 150°F rating mean for daily use?

The coupling is rated for a maximum operating pressure of 500 psi at temperatures up to 150 degrees Fahrenheit, suitable for high-pressure steam or water lines within those limits.

How does the NPT threaded interface affect installation?

The female NPT threads on both ends accept standard 1 1/4 inch male NPT pipe nipples, creating a tapered seal that tightens as the joint is assembled.
