Asc 390211209 Rigidlite Grooved Coupling 6 in 300 Psi

Product Description

The ASC Engineered Solutions 390211209 is a 6-inch Rigidlite grooved coupling rated for 300 psi service, manufactured from ductile iron. Grooved couplings of this type create a rigid mechanical joint between grooved pipe ends, eliminating the need for welding or threading on compatible piping systems. The rigid design limits angular deflection and pipe movement at the joint, making it appropriate for high-pressure mechanical systems. Weighing 5.20 pounds, the 390211209 is installed by pipefitters and plumbing professionals in commercial and industrial piping applications where dependable, pressure-rated joints are required.

This coupling is intended for use on 6-inch grooved-end pipe in mechanical piping systems operating up to 300 psi. Typical applications include HVAC hydronic systems, fire protection headers, industrial process piping, and commercial plumbing mains where grooved pipe joining is specified. The Rigidlite designation indicates a rigid-style coupling that controls pipe-end movement and maintains joint alignment under pressure and load conditions common to large-diameter installations.

Key Features

• Rigid coupling design controls pipe movement and maintains alignment at the joint
• Rated to 300 psi for use in high-pressure mechanical piping systems
• Ductile iron construction provides strength and durability in demanding service environments
• 6-inch nominal pipe size fits grooved-end pipe of corresponding dimension
• Mechanical joint eliminates field welding or threading at the connection point

Compatibility

Designed as an OEM-style grooved mechanical coupling for 6-inch grooved-end pipe conforming to standard groove dimensions used in commercial and industrial piping systems.

Installation Notes

Installation should be performed by a licensed pipefitter or qualified plumber in accordance with applicable mechanical codes. De-pressurize and drain the piping system fully before removing or installing any grooved coupling. Verify that pipe-end groove dimensions conform to the coupling manufacturer specifications before assembly. Inspect the gasket seat and housing lugs for damage before torquing the coupling bolts to the fastener manufacturer specification.
