Asc Engineered Solutions 390078848 Gruvlok Grade E Epdm Gasket 14 in

Product Description

The ASC ENGINEERED SOLUTIONS 390078848 is a Gruvlok Grade E EPDM replacement gasket designed for grooved pipe coupling systems used in commercial and industrial piping installations. Rated for a temperature range of -40 to 230 degrees F, this 14-inch nominal gasket is manufactured from green EPDM rubber and is designed for use with Gruvlok 7000-4 and 7400-01 couplings. The pressure-responsive sealing design compresses the inclined gasket lips against the pipe OD, creating a leak-tight seal that is further reinforced when the coupling housings encompass and compress the gasket body. Licensed plumbing and mechanical contractors install this component as part of grooved piping assemblies.

This gasket is suited for 14-inch nominal grooved pipe systems in commercial HVAC hydronic piping, fire protection, and industrial fluid handling applications. The EPDM elastomer compound performs reliably across a broad temperature range, making it appropriate for chilled water, hot water, and other compatible fluid services. It is domestically manufactured and intended as a direct OEM-style replacement for grooved coupling assemblies where the gasket requires periodic inspection and replacement.

Key Features

• Grade E EPDM elastomer rated from -40 to 230 degrees F
• 14-inch nominal size for Gruvlok grooved coupling systems
• Compatible with Gruvlok 7000-4 and 7400-01 couplings
• Pressure-responsive design: internal line pressure energizes the gasket and enhances sealing action
• Inclined gasket lips compress against pipe OD for a leak-tight seal
• Domestically manufactured green EPDM rubber construction

Compatibility

Designed for use with Gruvlok 7000-4 and 7400-01 couplings at 14-inch nominal pipe size. Verify pipe OD and groove dimensions meet Gruvlok specifications before installation.

Installation Notes

Installation is typically performed by licensed plumbing or mechanical contractors working on grooved piping systems. Before replacing a gasket, isolate and depressurize the affected pipe section and drain the line as required by applicable codes. Lubricate the gasket with a compatible, pipe-safe lubricant per the coupling manufacturer's instructions prior to seating. Do not use petroleum-based lubricants on EPDM gaskets, as they can degrade the elastomer.
