Questions about this item

Should I choose the 2-inch nominal size with 8-inch overall length for my piping run?

The nipple is a 2-inch nominal pipe size and 8 inches long overall, so select it when your system requires that exact diameter and length combination.

What does the 157 psi at 450 °F rating mean for everyday use?

It indicates the maximum pressure the nipple can withstand when the fluid temperature reaches 450 °F; at lower temperatures the allowable pressure is higher.

How does the MNPT thread and Class 150 rating limit the connection?

The male NPT threads seal with a matching female NPT fitting, and the Class 150 designation caps the pressure rating at 150 psi for standard flange-compatible service.
