O-Rings - EPDM, Peroxide-Cured, FDA, 80 Shore A

O-rings are circular sealing rings with a round cross-section. When an O-ring is fitted into a groove and compressed between two surfaces, it forms a seal that prevents the escape of liquids or gases. O-rings are suitable for both static and dynamic applications.

These O-rings are made from peroxide-cured EPDM (ethylene propylene diene monomer rubber). EPDM has excellent resistance to water, steam, ozone, sunlight and weathering. Compared with sulphur-cured EPDM, peroxide curing gives better heat resistance, better resistance to hot water and steam, and lower compression set, so the seal maintains its sealing force for longer. Because no sulphur is used in the curing process, there are no sulphur by-products to leach into the media being sealed. At 80 Shore A, the material offers greater resistance to extrusion than softer grades, while remaining more flexible than 90 Shore A.

The compound complies with FDA requirements for rubber articles intended for repeated use in contact with food.

Chemical Compatibility

EPDM is recommended for use with hot water and steam, glycol-based brake fluids, glycol-based coolants, alcohols, silicone oils, and dilute acids and alkalis.

Limitations

EPDM is not recommended for use with mineral oils and greases, petroleum-based hydraulic oils, petrol, diesel or other hydrocarbon fuels, aliphatic or aromatic hydrocarbons, or chlorinated solvents.

Applications

These O-rings are suitable for food and beverage processing equipment, steam sterilisation, hot water and steam systems, and valves.

Installation Guidance

Make sure that the groove and mating surfaces are clean and free from burrs. Use only a silicone-based lubricant when fitting, and make sure that it is suitable for food contact where required; never use mineral oil-based greases or oils, as these will damage EPDM. Do not stretch or roll the O-ring over sharp edges or threads.
