Asc Engineered Solutions 300508009 Cast Iron Tee 3/4 in Xh

Product Description

The ASC ENGINEERED SOLUTIONS 300508009 is a 3/4-inch extra-heavy (XH) black cast iron tee fitting designed for threaded pipe systems in demanding service environments. Cast iron construction with a black coating provides durability and corrosion resistance suitable for gas distribution, industrial piping, and mechanical systems. The tee configuration allows a branch connection at 90 degrees from the main run. At 1.54 pounds, this domestically produced fitting is built to 250-class pressure standards and is installed by licensed plumbers, pipefitters, and HVAC mechanics working on black iron pipe systems.

This fitting is suited for residential and light commercial applications where black iron pipe is required, including natural gas supply lines, propane distribution, steam systems, and general industrial piping. The extra-heavy wall rating makes it appropriate for elevated-pressure service beyond standard Class 150 fittings. It connects three segments of 3/4-inch threaded pipe in a branch configuration and is commonly used at supply takeoffs, meter sets, and manifold assemblies in mechanical rooms.

Key Features

• Extra-heavy (XH) wall rating for higher-pressure service compared to standard Class 150 fittings
• Cast iron construction for strength and durability in threaded pipe systems
• Black coating finish standard for gas and industrial piping applications
• 3/4-inch fitting size accommodates standard NPT threaded pipe
• Domestically manufactured

Compatibility

Designed as an OEM-style replacement or new-installation fitting for 3/4-inch threaded black iron pipe systems rated for extra-heavy service.

Installation Notes

Installation should be performed by a licensed plumber or pipefitter in accordance with applicable codes such as the IFGC or IPC. Shut off and depressurize the pipe system completely before disassembling any threaded connections. Apply an approved thread sealant or PTFE tape rated for the service medium before making up threaded joints. Do not over-torque cast iron fittings, as the material is not ductile and may crack under excessive force.
