Main Benefits of EPDM Flange Gasket

Chemical Resistance and Weather Durability

EPDM Flange Gasket offers outstanding protection against harsh chemicals and tough weather. This material stands up to polar fluids like glycol and phosphoric acid esters, making it a top choice for hydraulic and pneumatic systems. EPDM also resists hot water and steam, so it works well in both industrial plants and home appliances. Its chemical stability means it can handle dilute acids, alkalines, and polar solvents such as ketones and alcohols.

When exposed to sunlight, ozone, or strong winds, EPDM Flange Gasket keeps its strength. Its non-polar nature and special additives help it resist UV rays and oxidation. Many industries, including water treatment and food processing, trust EPDM for its safety and durability. The table below shows how EPDM compares to other common sealing materials:

Feature EPDM Rubber PVC Membrane TPO Membrane Bitumen-Based Membrane
Weather Resistance High Moderate High Moderate
Chemical Resistance High Moderate Moderate Low
Lifespan 50+ years 20-30 years 30+ years 20-25 years
Flexibility Excellent Moderate High Low

EPDM Flange Gasket stands out for its long lifespan and excellent resistance to both chemicals and weather, making it a reliable choice for demanding environments.

Temperature Flexibility and Mechanical Strength

EPDM Flange Gasket performs well in a wide range of temperatures. It stays flexible and strong from -30°F to 300°F, and some types can even handle short bursts up to 347°F. This makes it perfect for both cold and hot climates. Even after 1,000 hours of UV and ozone exposure, EPDM gaskets keep about 75% of their original strength.

  • EPDM gaskets resist heat, ozone, and steam.
  • They work in temperatures from -45°C to 150°C.
  • Some can handle short-term exposure up to 175°C.
  • These gaskets keep their shape and strength, even after years of use.

Many industries use EPDM Flange Gasket in brake fluid seals, radiator gaskets, and air conditioning systems. Its ability to handle both mechanical stress and temperature swings means fewer failures and more reliable performance.

Long Service Life and Low Maintenance

EPDM Flange Gasket delivers a long service life with minimal upkeep. Studies show that custom-molded EPDM gaskets keep their sealing power for over 10 years, even in harsh conditions. They resist wear, vibration, and repeated compression, which means they need less frequent replacement.

  • EPDM gaskets extend equipment lifespan by 5 to 10 years.
  • They lower maintenance costs by reducing the need for repairs.
  • Precision engineering and advanced molding help these gaskets last longer.
  • In a 12-month salt spray test, EPDM gaskets showed zero leaks, even in high-salt and high-vibration environments.

Choosing EPDM Flange Gasket means fewer interruptions, lower costs, and peace of mind for any water supply or industrial system.
