EPDM, short for Ethylene Propylene Diene Monomer, is chosen for sealing positions exposed to weather, ozone, heat, water and coolants. The seals and o-rings in this range are made from top-grade EPDM and are used across the automotive and electronic and electric industries, in daily necessities and sports equipment, in mechanised industrial equipment and other rubber products, and in wires, cables and high-voltage and ultra-high-voltage insulation materials. Typical sealing duty runs from heating systems and automotive brakes to water systems and refrigeration units, where resistance to coolants and refrigerants is required. Food-grade EPDM is available where the seal sits in pharmaceutical or food processing service.
Ozone and weather resistance keeps outdoor and vented assemblies sealed instead of cracking after a season of exposure
Coolant and refrigerant resistance makes it a safe default for refrigeration unit joints
Suitability for brake fluid positions avoids the swelling that hydrocarbon grade compounds show there
Food-grade EPDM available so pharmaceutical and food processing lines can keep one seal family
Proven in high-voltage and ultra-high-voltage insulation so cable and electrical work is covered by the same material
Seals exposed to weather and ozone crack and leak once the equipment has been outdoors for a period
Hydrocarbon grade compounds swell in brake fluid and lose their sealing force
Refrigerant attack on the wrong compound causes slow charge loss that is hard to diagnose
Non food-grade material blocks a seal from being used on a food or pharmaceutical line
Insulation components that degrade under heat shorten the service life of a cable assembly

EPDM is the correct choice for water coolant and brake fluid duty where nitrile would swell
EPDM holds up better in water and steam circuits and in weather exposed outdoor positions
Food-grade EPDM is specified where the seal contacts pharmaceutical or food product

Yes. EPDM is used in refrigeration units because of its resistance to coolants and refrigerants.
Yes. Food-grade EPDM is used for pharmaceutical and food processing applications. State the requirement on the enquiry so the correct grade is quoted.
In wires, cables and high-voltage and ultra-high-voltage insulation materials, as well as in automotive, electronic and electric industry parts, daily necessities, sports equipment and mechanised industrial equipment.
Yes. O-ring and shaped seal dimensions are made to your groove rather than to a stock size.
It depends on the size, grade and whether tooling exists for that profile, and it is confirmed in writing with the quotation.
