Asc Engineered Solutions 312822802 Ground Joint Union 3 Inch

Product Description

The ASC Engineered Solutions 312822802 is a 3-inch extra-heavy black iron ground joint union designed for threaded pipe assemblies in demanding service applications. Ground joint unions use a machined seat at the center joint to form a metal-to-metal seal, eliminating the need for a gasket and providing a reliable, leak-resistant connection. At 8.26 pounds, this fitting is built to the extra-heavy wall standard, suited for higher-pressure systems where standard-weight fittings are not adequate. Licensed plumbers and pipefitters install this type of union where sections of pipe must be disconnected and reconnected for service access.

This union is used in commercial and industrial piping systems carrying gas, steam, or liquid where a robust, reusable threaded connection point is required. The black iron finish and extra-heavy construction make it appropriate for above-ground and in-wall applications in mechanical rooms, boiler rooms, and process piping installations. Domestic manufacture supports projects with domestic-content requirements or specifications.

Key Features

• Extra-heavy wall construction for higher-pressure service ratings
• Ground joint metal-to-metal seat eliminates gasket dependency
• 3-inch fitting size for large-diameter threaded pipe runs
• Black iron material compatible with gas and steam service
• Domestically manufactured
• Reusable union design allows pipe disassembly without cutting

Compatibility

Designed as an OEM-style replacement or new-installation fitting for 3-inch threaded black iron pipe systems in commercial and industrial plumbing, gas, and steam applications.

Installation Notes

Installation should be performed by a licensed plumber or pipefitter in accordance with applicable local mechanical and plumbing codes, including IFGC and IPC requirements where relevant. Shut off and depressurize the system and verify zero pressure before disassembling or installing any union fitting. Apply listed thread sealant appropriate for the service medium to the male threads only, keeping sealant clear of the ground joint seating surfaces. Inspect the ground joint seat for nicks or debris before assembly to ensure a proper metal-to-metal seal.
