Asc Engineered Solutions 390007441 Plain End Coupling 8 in

Product Description

The ASC Engineered Solutions 390007441 is a Gruvlok Roughneck Plain End Coupling designed for use in grooved piping systems where reliable mechanical joining is required. Built from ductile iron, this 8-inch coupling provides a rigid, pressure-rated connection on plain-end pipe without requiring grooved pipe ends. At 36.80 pounds, it is a heavy-duty fitting suited for industrial, commercial, and large-diameter mechanical systems. Licensed plumbers, pipefitters, and mechanical contractors are the typical installers for this class of coupling.

The Roughneck Plain End Coupling is used in large-diameter piping applications including HVAC hydronic systems, fire protection mains, industrial process lines, and commercial plumbing distribution. The plain-end configuration allows installation on cut pipe without a grooving tool, making it a practical choice in retrofit situations or where field grooving equipment is not available. The 8-inch size is common in building mechanical rooms and large-diameter distribution headers.

Key Features

• Ductile iron construction for high strength and impact resistance in demanding mechanical environments
• Plain-end design eliminates the need for grooved pipe preparation
• 8-inch fitting size suits large-diameter commercial and industrial piping systems
• Gruvlok product line known for mechanical grooved coupling systems used in HVAC, fire, and process piping
• Heavy-duty build at 36.80 pounds reflects robust wall thickness appropriate for commercial-grade installations

Compatibility

Designed as an OEM-style replacement or new-installation fitting for 8-inch grooved mechanical piping systems using plain-end pipe configurations.

Installation Notes

Installation should be performed by a licensed pipefitter or plumber in accordance with applicable mechanical codes such as the IPC or ASME B31 piping standards. Depressurize and drain the piping system fully before removing or installing any coupling. Follow the manufacturer torque sequence for housing bolts to ensure proper gasket seating and a leak-free connection. Do not over-torque housing bolts or substitute non-rated fasteners.
