Questions about this item

What does the 3000 psi rating mean when the bushing is installed in a real piping system?

It indicates the maximum allowable working pressure at 100°F for the Class 3000 fitting, so the system must not exceed that pressure at that temperature.

How does the MNPT x FNPT thread standard limit what pipes can connect to this bushing?

The threads follow ANSI/ASME B1.20.1, so only matching NPT male and female threads will seal properly; other thread forms will not engage.

What clearance does the hex body need for a wrench during installation?

The hex profile is designed for standard wrench flats, allowing a typical open-end or adjustable wrench to grip and turn the fitting.
