Questions about this item

What does the 175 psi rating mean when this bushing is installed in a live system?

The 175 psi rating is the maximum operating pressure at 150 degrees Fahrenheit, so the joint will hold that pressure at that temperature without leaking or deforming.

How does the NPT thread standard affect what pipe this bushing can connect to?

Both the 4-inch male and 1-1/2-inch female ends use NPT threads, so the bushing only mates with NPT-threaded pipe or fittings of matching nominal sizes.
