Asc 390007375 Gruvlok Roughneck Plain End Coupling 2.5 in

Product Description

The ASC Engineered Solutions 390007375 is a Gruvlok 7005-E Roughneck Plain End Coupling designed for joining plain-end pipe in mechanical piping systems. This ductile iron coupling provides a rigid, secure connection without requiring grooved pipe ends, making it well suited for installations where cutting grooves is impractical. At 2.5 inches in size and weighing 7.35 pounds, it is a heavy-duty fitting built for demanding commercial and industrial piping applications. Licensed plumbers and pipefitters typically specify this coupling where plain-end connections are required within fire protection, HVAC, or mechanical piping layouts.

This coupling is intended for use in commercial and industrial mechanical piping systems that require plain-end pipe joining at the 2.5-inch nominal pipe size. It is commonly installed in HVAC hydronic loops, fire protection distribution lines, and general-purpose mechanical piping where the Gruvlok system is already in use. The 7005-E Roughneck design is selected when grooved-end fittings are not feasible or when retrofitting into existing plain-end piping runs.

Key Features

• Plain-end design eliminates the need for grooved pipe preparation
• Ductile iron construction provides high strength and impact resistance
• 2.5-inch fitting size fits standard nominal pipe dimensions
• Part of the Gruvlok 7005-E Roughneck coupling series for consistent system compatibility
• Rigid coupling style maintains pipe alignment under system pressure and vibration

Compatibility

Designed as an OEM-style replacement and standard component for Gruvlok mechanical piping systems using 2.5-inch plain-end pipe. Confirm pipe outside diameter and system pressure rating before installation.

Installation Notes

Installation is typically performed by licensed plumbers or pipefitters. Shut off and depressurize the piping system completely before removing or installing any coupling. Follow the manufacturer torque sequence for housing bolts and inspect gasket seating before returning the system to service. Installations in fire protection systems must comply with NFPA 13 and all applicable local codes.
