Malleable Iron Reducer Coupling

This Anvil reducer coupling joins 1-1/2 inch and 1 inch FNPT pipe ends in drainage systems. The Class 150 malleable iron body handles saturated steam up to 150 psi at 350 Degrees F and water pressure up to 300 psi at 150 Degrees F. It meets ASME B 16.3 and carries UL and FM approvals for code-compliant installations.

Suitable Installations and Limits

The fitting suits hot and cold water, steam and compressed air lines within the rated pressure and temperature range of -20 to 350 Degrees F. Installers needing larger step-down sizes, different thread types or higher pressure classes must select alternative fittings. It is not intended for applications exceeding the stated pressure or temperature limits.

Critical Sizing and Rating

The connection is defined by the 1-1/2 in x 1 in FNPT sizing and the Class 150 pressure rating of 300 psi at 150 Degrees F. Verify that both pipe ends match these dimensions and that the system design stays within the maximum saturated steam pressure of 150 psi at 350 Degrees F.
