3/4" Cast Iron Elbow

The Anvil 0300030004 is a 3/4 inch cast iron elbow designed for drainage and trap installations. It provides a 22-1/2 degree change of direction in piping systems. The fitting uses FNPT threads for connection. It meets ASME B16.4 standards and carries UL and FM approvals.

Threaded Installation Details

The FNPT connection allows the elbow to thread directly onto male pipe threads without soldering or welding. Cast iron construction requires pipe thread sealant or tape to prevent leaks at the joint. Over-tightening can crack the fitting body. The Class 125 rating defines its pressure boundary for drainage service.

Pressure and Temperature Limits

The fitting is rated for a maximum pressure of 175 psi at temperatures from -20 to 150 degrees Fahrenheit. Saturated steam service is limited to 125 psi within the same temperature range. These limits determine whether the part suits the intended system pressure. Systems exceeding these values require a different class of fitting.

Questions about this item

How can I confirm the 3/4 inch FNPT elbow is seated correctly after installation?

Pressure-test the joint up to 175 psi at temperatures between -20 and 150 °F; a leak-free hold confirms the Class 125 cast-iron fitting is working as intended.

What comes with the Anvil 0300030004 elbow and what must I supply?

The box contains only the 22-1/2° cast-iron elbow; you must provide 3/4 inch NPT pipe nipples, thread sealant and any required hangers or supports.

Which version of the 3/4 inch cast-iron elbow should I choose for 125 psi saturated steam service?

This model meets ASME B16.4 and is rated for 125 psi saturated steam at up to 150 °F, making it the correct Class 125 selection for that duty.
