Malleable Iron Tee Class 300
This malleable iron tee provides a three-way connection for piping systems requiring Class 300 pressure ratings. It is suited for industrial, commercial and residential plumbing installations where threaded joints are specified.
Check thread type and pressure class
Verify that your existing piping uses FNPT threads and that the system design calls for a Class 300 fitting rated for 1500 psi at 150 degrees F. Confirm the operating temperature stays within the minus 20 to 550 degrees F range and that the nominal pipe size matches 1-1/2 in.

The fitting meets ASME B 16.3 and B 16.4 standards and complies with ASTM A47 and ASTM A197 material specifications. FNPT threads allow direct assembly onto male-threaded pipe without welding or flanges, simplifying installation and future maintenance.
