Questions about this item

Should I choose the 3/4 inch FNPT tee or a different pipe size?

This tee is supplied in a single 3/4 inch FNPT size. Select it when your piping uses 3/4 inch female National Pipe Thread connections and you need a Class 300 branch.

What does the 2000 psi at 150 °F rating mean once the tee is installed?

It means the fitting can safely handle up to 2000 psi non-shock pressure at 150 °F, and up to 300 psi saturated steam within the -20 °F to 550 °F temperature range.

How does the ASME B16.3 and B16.4 standard cap the working pressure in practice?

The standards define the Class 300 pressure-temperature envelope, so the 2000 psi at 150 °F and 300 psi steam limits are the maximum allowable non-shock pressures for this malleable iron tee.
