Grooved Coupling Gaskets

Grooved Standard "C" Gaskets are designed for dependable sealing performance in grooved piping systems used throughout commercial, industrial, HVAC, fire protection, and water distribution applications. Available in both EPDM and Nitrile compounds, these gaskets provide reliable sealing across a wide range of temperatures and service conditions.

Engineered for use with grooved mechanical couplings, Standard "C" gaskets help maintain leak-resistant joints while accommodating normal system movement, vibration, and thermal expansion.

General Service Applications

Suitable for water, dilute acids, alkalies, salts, and many chemical services that do not involve hydrocarbons, oils, lubricants, or gases.

EPDM compounds provide excellent oxidation resistance, making them well-suited for water distribution, HVAC, cooling water, and other general service piping systems.

Construction Details

Manufactured from high-quality elastomer compounds, Standard "C" gaskets are engineered to provide long-lasting sealing performance in grooved piping systems.

EPDM gaskets are optimized for water-based applications and offer superior resistance to oxidation and weathering, while Nitrile gaskets provide an alternative compound option for selected service requirements.

The gasket profile is designed to create a positive seal within grooved coupling housings while maintaining flexibility and reliability over time.

Important Notes

EPDM operating temperature range: -30°F to +230°F. Nitrile operating temperature range: -20°F to +180°F.

EPDM gaskets are NOT FOR USE WITH HYDROCARBONS, LUBRICANTS, OR OILS.

Always verify gasket compound compatibility with the intended media, operating pressure, and temperature before installation.
