The ASC ENGINEERED SOLUTIONS 300033008 is a 3-inch black cast iron tee fitting used in threaded pipe systems for gas distribution, plumbing drain lines, and general industrial piping. Cast from domestic black iron, this tee provides a durable branch connection point in straight runs of pipe. The fitting handles the mechanical stress and pressure demands common in commercial and residential gas piping and low-pressure steam or water systems. Licensed plumbers, pipefitters, and gas technicians are the primary installers of this type of fitting.
This tee is suited for residential and light commercial applications where a 3-inch branch takeoff is required. Common install scenarios include main gas supply lines, black iron piping manifolds, and industrial process piping. The domestic manufacture designation makes this fitting appropriate for projects where country-of-origin requirements apply, such as certain municipal or federal job specifications.
Designed as an OEM-style replacement and new-install fitting for 3-inch threaded black iron pipe systems in gas, steam, and general-purpose industrial piping applications.
Installation should be performed by a licensed plumber or pipefitter in accordance with applicable local codes, IFGC requirements for gas piping, or ASME B31.3 for process piping. Shut off and depressurize the line completely before cutting into an existing system. Apply listed pipe thread sealant or PTFE tape rated for the service medium to all threaded connections. Do not use this fitting in systems exceeding the pressure or temperature ratings of standard black cast iron threaded fittings without verifying the system design.
