ISO 3601 Excellent Weathering Resistance EPDM Rubber O Rings Seals for Industrial Applications

EPDM Rubber O-Rings: English Introduction

EPDM Rubber O-Rings are sealing components made from Ethylene Propylene Diene Monomer (EPDM), a synthetic rubber known for its excellent resistance to weathering, ozone, UV radiation, and extreme temperatures. These O-rings are widely used in various industries due to their durability and chemical stability.

Key Features:

• Weather & Ozone Resistance: Ideal for outdoor applications, as EPDM resists degradation from sunlight and atmospheric conditions.

• Temperature Resistance: Performs well in a broad range, typically from -50°C to +150°C (-58°F to +302°F).

• Chemical Resistance: Resists water, steam, alkalis, acids, and polar solvents, but not recommended for petroleum-based oils or fuels.

• Flexibility & Elasticity: Maintains sealing properties even in dynamic applications.

Common Applications:

• Automotive: Cooling systems, brake systems, and HVAC components.

• Plumbing & HVAC: Water seals, gaskets, and pipe connections.

• Electrical: Insulating seals for enclosures exposed to moisture.

• Industrial: Seals for pumps, valves, and hydraulic systems (non-oil applications).

Advantages Over Other Elastomers:

✔ Better heat and steam resistance than Nitrile (NBR).
✔ Superior ozone/weather resistance compared to Natural Rubber.
✔ More cost-effective than Silicone for many applications.

EPDM O-rings are a reliable choice for sealing in harsh environments where oxidation, water, or temperature fluctuations are concerns. For oil or fuel exposure, alternative materials like Nitrile (NBR) or Fluorocarbon (FKM) are recommended.
