Asc Engineered Solutions 812508018 Black Malleable Iron Union

Product Description

The ASC ENGINEERED SOLUTIONS 812508018 is a black-coated malleable iron union fitting sized at 1/2 inch. Unions allow a section of pipe to be disconnected and reconnected without rotating the pipe itself, making them a standard component in gas, air, and low-pressure fluid piping systems. The malleable iron construction provides the ductility and thread integrity required for threaded black iron piping assemblies. Licensed plumbers and pipefitters install this fitting in residential and light commercial applications where periodic service access to a pipe run is needed.

This 1/2 inch union is suited for threaded black iron pipe systems commonly found in natural gas supply lines, compressed air distribution, and steam or hydronic heating piping. The black coating is standard for gas piping applications and is compatible with NPT-threaded pipe in that size. It is an imported fitting appropriate for maintenance, repair, and new installation work where a union connection point is required.

Key Features

• 1/2 inch fitting size for use with standard NPT-threaded black iron pipe
• Malleable iron construction provides strength and ductility in threaded piping systems
• Black coating standard for gas and general-purpose black iron piping assemblies
• Union design allows pipe disconnection without rotating adjacent pipe sections
• Weighs 0.41 pounds per unit for straightforward field handling

Compatibility

Designed as an OEM-style replacement or new-installation fitting for 1/2 inch threaded black malleable iron pipe systems.

Installation Notes

Installation should be performed by a licensed plumber or pipefitter in accordance with applicable local codes and the International Fuel Gas Code (IFGC) or International Plumbing Code (IPC) where gas or fluid piping is involved. Shut off and depressurize the affected pipe section before disassembly. Apply appropriate thread sealant rated for the service medium to all male threads before assembly. Do not overtighten threaded malleable iron fittings, as excessive force can crack the fitting body.
