This gallery provides a look at some of our gaskets and seals molded with EPDM.

Ethylene Propylene Diene Monomer (EPDM) offers strong resistance to weathering and ozone. Our OEM customers often prefer EPDM as cost-effective material for seals used in environments that do not involve harsh fluid exposure, such as petroleum oils, transmission fluids, or solvents. Typical uses include grommets and press-in-place (PIP) gaskets.

Key Characteristics of EPDM

Excellent Weather and Ozone Resistance
EPDM is particularly valued for its resistance to UV light, ozone, and outdoor weathering. This makes it ideal for use in external sealing applications, such as under-hood or body-mounted automotive gaskets and outdoor industrial equipment.

Wide Temperature Tolerance
EPDM performs well across a broad temperature range, typically from -50°C to +150°C, and up to +180°C in some formulations. This thermal flexibility makes it suitable for cooling system gaskets, HVAC seals, and steam applications.

Superior Water and Steam Resistance
EPDM is highly resistant to water, steam, and glycols, making it an excellent material for coolant seals, heater hoses, and water system gaskets in both automotive and industrial settings.

Chemical Compatibility
EPDM exhibits good resistance to acids, alkalis, and oxygenated solvents, though it is not compatible with petroleum-based oils or fuels. For oil- or fuel-exposed applications, other elastomers such as NBR or FKM are more appropriate.

Elasticity and Compression Set Resistance
EPDM maintains its flexibility and elasticity over time, even in harsh environments. Its low compression setallows it to recover its shape after compression, maintaining a tight and reliable seal under pressure and thermal cycling.

Electrical Insulation Properties
EPDM offers excellent electrical resistance, making it suitable for sealing electrical enclosures or protecting connectors in automotive systems.

Noise and Vibration Dampening
Due to its inherent flexibility and resilience, EPDM is effective at damping vibration and reducing noise, making it useful in automotive body sealing and industrial enclosures where NVH (noise, vibration, harshness) control is desired.
