Asc Engineered Solutions 310521208 Black Malleable Iron Tee Sch 80

Product Description

The ASC ENGINEERED SOLUTIONS 310521208 is a black malleable iron tee fitting rated for Schedule 80 service at 300 PSI. It features a 1-inch run on both ends and a 3/4-inch branch outlet, with threaded connections on all three ports. This fitting is used to split or combine pipe flow in threaded iron piping systems. Plumbers, pipefitters, and mechanical contractors install this type of fitting in gas distribution, steam, compressed air, and hydronic heating systems where a durable, pressure-rated iron fitting is required.

This tee is suited for both residential and light commercial piping installations. Its reducing branch configuration makes it a standard choice when the main run is 1 inch and a 3/4-inch branch connection is needed, such as tapping off a supply main to feed a zone, appliance, or service drop. The black finish indicates it is not galvanized and is commonly used in gas piping, fire suppression rough-in, and industrial fluid handling applications.

Key Features

• Black malleable iron construction provides strength and resistance to mechanical stress
• Schedule 80 rated fitting suitable for 300 PSI service pressure
• Threaded connections on all three ports for standard NPT pipe assembly
• 1 inches x 1 inches run with 3/4 inches reducing branch outlet
• Black finish appropriate for gas piping and non-corrosive fluid systems

Compatibility

Designed as an OEM-style replacement fitting for threaded black malleable iron piping systems using NPT connections.

Installation Notes

Installation should be performed by a licensed plumber or pipefitter in accordance with applicable local codes, the International Fuel Gas Code (IFGC), or the International Plumbing Code (IPC) depending on the service. Shut off and depressurize the affected pipe section before cutting in or replacing any fitting. Apply an approved thread sealant or PTFE tape to male threads before assembly. Do not overtighten threaded connections, as malleable iron fittings can crack under excessive torque.
