Questions about this item

Should I choose this 2-1/2 in FNPT elbow or a different size for my system?

Select this elbow when your piping uses 2-1/2 in FNPT threads and requires a 90 degree turn; match the pipe size and connection type exactly to avoid leaks.

What does the Class 300 rating mean once the elbow is installed?

It indicates a maximum working pressure of 1000 psi at 150 degrees F and 300 psi saturated steam at 550 degrees F, with a temperature range from -20 to 550 degrees F.

Which standards apply to the FNPT threads and how do they limit use?

The fitting meets ASME B 16.3 and is AAR Approved, FM Approved, and UL Listed, so it complies with those standards for pressure piping and fire protection systems.
