Asc Engineered Solutions 300033404 Black Cast Iron Tee 4 in

Product Description

The ASC ENGINEERED SOLUTIONS 300033404 is a black cast iron tee fitting sized for 4-inch pipe. This fitting creates a three-way branch connection in a piping run, allowing flow to be directed or split at a 90-degree lateral outlet. Black cast iron tees are standard in gas distribution, industrial piping, and fire suppression systems where durability and pressure resistance are required. At 17.07 pounds, this is a heavy-duty fitting built for permanent, threaded installations. Licensed plumbers, pipefitters, and gas technicians are the typical installers for this class of fitting.

This fitting is suited for 4-inch threaded pipe assemblies in residential and commercial applications. Common install scenarios include natural gas mains, propane distribution headers, and industrial process piping. It is also used in fire suppression wet and dry systems where cast iron fittings meet code requirements. The fitting integrates into standard NPT-threaded runs and pairs with schedule 40 or schedule 80 black iron pipe of the same nominal size.

Key Features

• Black cast iron construction for strength and corrosion resistance in gas and industrial piping systems
• 4-inch nominal size fits standard NPT-threaded pipe of the same diameter
• Three-way tee configuration creates a 90-degree branch outlet from the main run
• Domestically manufactured fitting
• Heavy-duty mass at 17.07 pounds indicates robust wall thickness suitable for pressure service

Compatibility

Designed as an OEM-style replacement or new-installation fitting for 4-inch black iron threaded pipe systems in gas, industrial, and fire suppression piping applications.

Installation Notes

Installation should be performed by a licensed plumber, pipefitter, or gas technician in accordance with applicable local codes and IFGC or IPC requirements. Shut off and purge the gas supply or depressurize the water system completely before working on any threaded connection. Apply an approved pipe thread sealant or PTFE tape rated for the service medium to all male threads before assembly. Do not use this fitting beyond the pressure and temperature ratings appropriate for standard black cast iron threaded fittings in your jurisdiction.
