Asc Engineered Solutions 390211183 Grooved Coupling 5 in

Product Description

The ASC Engineered Solutions 390211183 is a RigidLite grooved coupling designed for rigid pipe joint connections in pressurized piping systems. Built from ductile iron, this 5-inch coupling handles working pressures up to 300 psi, making it suitable for demanding mechanical and fire protection piping applications. The 7400-E series design provides a rigid, zero-flex joint that maintains pipe alignment under system pressure. Licensed plumbers, pipefitters, and fire sprinkler contractors are the primary installers of this type of coupling.

This coupling is used in grooved-end piping systems where a rigid joint is required to resist pipe movement and maintain precise alignment. Typical applications include HVAC hydronic distribution, industrial process piping, and fire protection mains. The 5-inch size fits standard grooved-end pipe sections cut or roll-grooved to manufacturer groove specifications. It is suited for both new construction and retrofit work in commercial and industrial settings.

Key Features

• Ductile iron construction for strength and durability in high-pressure service
• Rated to 300 psi working pressure for demanding piping applications
• 5-inch nominal size fits standard grooved-end pipe
• Rigid joint design maintains pipe alignment and prevents angular deflection
• 7400-E series grooved coupling for use in mechanical, HVAC, and fire protection systems

Compatibility

Designed as an OEM-style grooved coupling for use with standard 5-inch grooved-end pipe in rigid-joint piping assemblies.

Installation Notes

Installation should be performed by a licensed pipefitter, plumber, or fire protection contractor following applicable codes such as NFPA 13 for fire protection systems or the IPC for mechanical piping. Depressurize and drain the piping system fully before coupling installation or removal. Verify that pipe ends are grooved to the correct groove dimensions for the 5-inch coupling before assembly. Inspect the gasket seat and housing keys for damage prior to torquing the coupling bolts.
