1/2" Cast Iron Cross Fitting
This Anvil 0300108701 cross fitting is a Class 125 cast iron component designed for drainage systems. It provides a four-way connection point with 1/2 inch FNPT threads on all outlets. The fitting meets ASME B16.4 standards and carries UL and FM approvals for code-compliant installations.
Suited for low-pressure drainage networks
Installers working on residential or light commercial drain, waste, and vent lines will find this fitting matches the required pressure class. It is not intended for high-pressure hydraulic circuits, potable water supply lines, or applications exceeding the rated temperature and pressure limits.
Handles 175 psi at 150 °F
The casting is rated for a maximum working pressure of 175 psi between -20 °F and 150 °F, with a saturated steam limit of 125 psi. It comfortably serves standard gravity drainage and low-pressure venting, but lacks the pressure class for steam mains or process piping above 125 psi steam.

Questions about this item
What pipe size and thread type must the existing piping have to connect this 1/2" FNPT cast iron cross?
The cross requires 1/2 inch piping with male NPT threads to match its female NPT connections on all four ports.
Will this Class 125 cast iron cross handle the pressure and temperature of my current steam or water system?
It is rated for 175 psi from -20 to 150 degrees F and 125 psi saturated steam within the same temperature range, meeting ASME B16.4.
How can I confirm the cross is installed correctly and performing to its rated limits?
Verify leak-free joints at all four FNPT ports, then confirm system pressure does not exceed 175 psi and temperature stays between -20 and 150 degrees F.
