EPDM O-rings
EPDM O-rings are sealing components made from Ethylene Propylene Diene Monomer (EPDM) rubber material. Here’s an overview of EPDM O-rings:
Material: EPDM is a synthetic rubber known for its excellent resistance to weathering, ozone, UV exposure, and heat. It also offers good resistance to water, steam, and many chemicals. EPDM is commonly used in outdoor and automotive applications due to its durability and resistance to environmental factors.
Cross-Sectional Design: EPDM O-rings have a circular cross-section, which is typical of traditional O-rings. This design allows them to fit into grooves or cavities between two mating surfaces, creating a seal to prevent the leakage of fluids or gases.
Applications: EPDM O-rings are widely used in various industries and applications where resistance to weathering, ozone, UV exposure, and heat is crucial. Common applications include automotive, HVAC, plumbing, water and steam applications, and outdoor equipment. EPDM O-rings are suitable for sealing against water, steam, and certain chemicals.
Advantages:
- Weather Resistance: EPDM O-rings offer excellent resistance to weathering, ozone, and UV exposure, making them ideal for outdoor applications exposed to harsh environmental conditions.
- Temperature Resistance: EPDM rubber can withstand a wide temperature range, from -50°C to +150°C (-58°F to +302°F), making EPDM O-rings suitable for both hot and cold environments.
- Chemical Resistance: EPDM has good resistance to water, steam, and many chemicals, making EPDM O-rings suitable for various sealing applications in industrial and automotive settings.
- Durability: EPDM rubber is known for its durability and long service life, even in challenging operating conditions. EPDM O-rings offer reliable sealing performance and can withstand repeated compression and expansion cycles without losing their sealing effectiveness.
Installation and Maintenance:
- Proper installation of EPDM O-rings is essential for ensuring effective sealing performance and the integrity of the sealing system.
- Seals should be installed in clean, properly sized grooves with adequate lubrication to minimize friction and prevent damage to the seal.
- Regular inspection and replacement of worn or damaged EPDM O-rings are necessary to maintain optimal sealing performance and prevent leaks.
EPDM O-rings provide reliable and cost-effective sealing solutions for a wide range of industrial and commercial applications. Proper selection, installation, and maintenance of EPDM O-rings are essential for ensuring reliable and effective sealing performance.
O-rings EPDM - 70 Shore A
EPDM O-rings, with a Shore A hardness of 70, offer excellent resistance to weathering, ozone, and UV exposure, making them ideal for outdoor applications. Their elasticity and durability ensure reliable sealing in various environments, including automotive, aerospace, and industrial settings. EPDM’s resistance to water, steam, and chemicals enhances its versatility. The Shore A 70 hardness strikes a balance between flexibility and rigidity, ensuring effective sealing without excessive compression set. Overall, EPDM O-rings provide long-lasting performance and reliability in demanding conditions.
O-rings EPDM - 80 Shore A
EPDM O-rings with an 80 Shore A hardness rating offer increased rigidity compared to softer variants, making them suitable for applications requiring tighter seals and higher pressure environments. This higher durometer rating enhances their resistance to deformation under compression, ensuring reliable sealing performance over time. EPDM’s inherent properties, such as excellent weather resistance, ozone resistance, and thermal stability, remain intact with this hardness level. These O-rings are commonly used in automotive, HVAC, and hydraulic systems where a firmer seal is required to prevent leaks and maintain system integrity.
O-rings EPDM - 70 Shore A - Peroxide Cured
EPDM O-rings with a Shore A hardness of 70, peroxide cured, offer enhanced chemical and temperature resistance compared to standard sulfur-cured EPDM. Peroxide curing results in cross-linking of polymer chains, improving the material’s resistance to aggressive fluids, such as oils, fuels, and solvents. Additionally, peroxide-cured EPDM exhibits better thermal stability, making it suitable for high-temperature applications up to 150°C (302°F) or even higher depending on the specific formulation. These O-rings maintain EPDM’s excellent weathering, ozone resistance, and UV stability while providing superior performance in demanding environments where exposure to harsh chemicals and elevated temperatures is common.
O-rings EPDM - 60 Shore A - Peroxide Cured
EPDM O-rings with a Shore A hardness of 60, peroxide cured, offer a balance of flexibility and durability, making them suitable for various sealing applications. The peroxide curing process enhances the material’s resistance to chemicals and high temperatures, making it ideal for use in environments where exposure to aggressive fluids or elevated temperatures is a concern. These O-rings maintain EPDM’s excellent weathering, ozone resistance, and UV stability while providing improved performance in demanding conditions. The softer Shore A 60 hardness allows for easier deformation and better sealing performance in applications where lower compression forces are desired.
O-rings EPDM - 70 Shore A - Peroxide Cured FDA
EPDM O-rings with a Shore A hardness of 70, peroxide cured and compliant with FDA regulations, are specifically designed for applications where contact with food and beverage products is involved. The peroxide curing process enhances the material’s resistance to chemicals and high temperatures, ensuring its suitability for use in food processing and pharmaceutical industries. These O-rings maintain EPDM’s excellent weathering, ozone resistance, and UV stability while meeting the stringent requirements of FDA regulations for food contact materials. They provide reliable sealing performance while ensuring compliance with food safety standards, making them an ideal choice for critical sealing applications in the food and beverage industry.
