Epdm Rubber Gaskets

Due to the EPDM rubber materials’ excellent resistance to aging, ozone, and weathering, the EPDM rubber gaskets are widely used in external applications. The EPDM gaskets are made of EPDM rubber elastomer and have an impermeable surface which is ideal for use with most alkalines, ketones and diluted acids, offering strong abrasion resistance.

EPDM Gaskets – Resistance

In medium-range sealing applications, EPDM gaskets are widely used and as flange gaskets, manway seals or low-pressure pipe seals. We offer EPDM Gaskets in food-safe or Drinking water approved versions – from FDA or WRAS/WRc certified. Our specialty are regular EPDM gaskets as well as white food quality EPDM gaskets for use with potable drinking water or for foodstuffs.

EPDM gaskets are the most often specified gasket choice because of their ozone resistance. If your gasket will be outdoors and exposed to temperatures between -40 C and 120 C the EPDM gasket is a great choice.


Ethylene Propylene Diene Monomer (EPDM):

EPDM gaskets are made of a black plate finish sheet with superior resistance to weathering, ozone and UV exposure. EPDM gaskets provide excellent chemical resistance*, and good electrical properties. EPDM gaskets resist animal and vegetable oils, steam, water and oxygenated solvents. This material meets ASTM D-2000-2BA specifications.

We cut gaskets from EPDM sheet gasket material to produce EPDM gaskets. Gaskets cut from 1, 2, 3, 4, 5, 6, 8, 10 mm using EPDM Material.

Please note that the EPDM rubber gaskets are Not oil resistant. Temperature range: -40C to 120C

EPDM rubber gaskets are sealing components made from EPDM (Ethylene Propylene Diene Monomer) rubber material. EPDM is a synthetic elastomer known for its excellent weather resistance, heat resistance, and resistance to ozone, UV radiation, and various chemicals. EPDM rubber gaskets are widely used in a variety of industrial applications where a reliable and durable sealing solution is required. Here’s a detailed description of EPDM rubber gaskets:

1. Material Composition:

  • EPDM Rubber: EPDM is the primary material used in the manufacturing of these gaskets. It is a synthetic rubber compound composed of ethylene, propylene, and a diene monomer, which gives it its desirable properties.

2. Functionality:

  • Sealing: The primary function of EPDM rubber gaskets is to create a secure and effective seal between two surfaces, preventing the leakage of fluids, gases, or contaminants. They are commonly used to provide a barrier against water, air, dust, and other environmental elements.

3. Features and Characteristics:

  • Weather Resistance: EPDM rubber gaskets are highly resistant to weathering, including exposure to sunlight (UV radiation), ozone, and extreme temperatures. This makes them suitable for outdoor and long-term applications.
  • Chemical Resistance: EPDM rubber has good resistance to a wide range of chemicals, acids, alkalis, and polar solvents, making it versatile in various industrial environments.
  • Heat Resistance: EPDM gaskets can withstand high temperatures without significant degradation, making them suitable for applications where heat resistance is required.
  • Compression Set Resistance: EPDM rubber exhibits excellent compression set resistance, meaning it can maintain its shape and sealing properties even after prolonged compression.
  • Flexibility and Elasticity: EPDM rubber is flexible and elastic, allowing it to conform to irregular surfaces and provide a tight seal even under varying conditions.
  • Low-Temperature Flexibility: EPDM remains flexible and functional at low temperatures, which is essential for cold-weather applications.
  • Tear Resistance: EPDM rubber is known for its resistance to tearing and abrasion, ensuring long-lasting durability.
  • Electrical Insulation: EPDM is an electrical insulator, making it suitable for electrical enclosure gaskets and applications where electrical insulation is required.

4. Applications:

  • Automotive: EPDM rubber gaskets are used in automotive applications, including door seals, window seals, weatherstripping, and gaskets for engine components.
  • Construction: They are employed in the construction industry for sealing doors, windows, roofing, and HVAC systems to ensure weatherproofing and energy efficiency.
  • Electronics: EPDM rubber gaskets are used in electronic enclosures and outdoor electrical installations to provide protection against moisture and dust.
  • Pipelines and Plumbing: EPDM gaskets are used in pipeline and plumbing systems for water and gas sealing, as well as in sewage and wastewater systems.
  • Aerospace: EPDM gaskets find applications in the aerospace industry for sealing aircraft components and systems.
  • Industrial Equipment: EPDM rubber gaskets are used in various industrial equipment, machinery, and pumps for sealing purposes.
  • Marine: They are used in marine applications to seal hatches, doors, and access points on boats and ships.

In summary, EPDM rubber gaskets are versatile sealing components known for their excellent resistance to weather, chemicals, heat, and low temperatures. Their durability and adaptability make them suitable for a wide range of applications across various industries, where reliable and long-lasting sealing solutions are essential.
