The ASC Engineered Solutions 300512605 is a black extra-heavy (XH) cast iron reducing tee designed for threaded pipe systems in commercial and industrial plumbing and gas distribution applications. The fitting transitions from a 1-1/2 inch run to a 3/4 inch branch outlet and is coated in black to meet standard requirements for gas and other non-potable piping systems. At 3.90 pounds, the fitting reflects the mass and durability characteristic of extra-heavy cast iron construction. Installation is performed by licensed plumbers and pipefitters working on black iron piping systems.
This reducing tee is suited for use in black iron piping systems handling natural gas, propane, compressed air, steam, and similar services where threaded cast iron fittings are specified. The extra-heavy wall rating provides added pressure capacity over standard-weight fittings, making it appropriate for higher-demand commercial and industrial environments. The domestic origin supports project specifications that require domestically manufactured pipe fittings.
Designed as an OEM-style replacement or new-install fitting for threaded black iron piping systems using 1-1/2 inch main run pipe with a 3/4 inch branch takeoff.
Installation should be performed by a licensed plumber or pipefitter in accordance with applicable codes such as the International Fuel Gas Code (IFGC) or International Plumbing Code (IPC). Shut off and depressurize the piping system completely before cutting into or disassembling any section. Apply an approved thread sealant or PTFE tape rated for the intended service before making up threaded connections. Do not overtighten threaded cast iron fittings, as cast iron is brittle and can crack under excessive torque.
