  • 90-degree turn redirects flow efficiently in tight piping layouts
  • Class 300 malleable iron withstands 2000 psi at 150 degrees F for demanding service
  • FNPT threads seal directly to 1-inch pipe without extra adapters
  • Meets ASME B16.3, B16.4, ASTM A197 and A47 for code-compliant installations
  • FM Approved and UL Listed for fire-protection and safety-critical systems

Malleable Iron 90 Degree Elbow Class 300

This malleable iron elbow provides a 90 degree change in piping direction for 1 inch FNPT connections. It is rated Class 300 for saturated steam service up to 300 psi and handles temperatures from -20 to 550 degrees F. The fitting meets ASME B16.3 and B16.4 standards along with ASTM A197 and A47 specifications.

Verify Thread Size Pressure Rating

Confirm your piping system uses 1 inch FNPT threads before ordering this elbow. Check that the operating pressure does not exceed 2000 psi at 150 degrees F or 300 psi for saturated steam applications. Ensure the system temperature stays within the -20 to 550 degrees F range and that malleable iron is compatible with the conveyed fluid.

FM Approved UL Listed Fitting for Steam

This elbow integrates into plumbing systems requiring FM Approved and UL Listed components for safety compliance. It connects directly to other 1 inch FNPT fittings, valves or pipe nipples without adapters. The Class 300 rating supports high-pressure steam lines while the malleable iron construction withstands mechanical stress and thermal cycling in industrial installations.

Questions about this item

Does the elbow ship with any gaskets, sealant or extra fittings, or must I buy those separately?

The fitting is supplied as a single malleable iron 90 degree elbow with 1 in FNPT threads; thread sealant, gaskets and any mating nipples or couplings are not included and must be purchased separately.

How do I decide between Class 300 and a lower-pressure class for a 1 in line?

Choose Class 300 when the system runs up to 2000 psi at 150 °F or 300 psi saturated steam; lower classes are rated for less pressure and would not meet ASME B16.3 requirements for those conditions.

What does the 2000 psi rating mean once the elbow is installed in a hot-water loop?

At the maximum 150 °F operating temperature the elbow withstands 2000 psi non-shock pressure; above that temperature the allowable pressure drops according to the ASME B16.3 pressure-temperature curve.
