Product Overview
Seals and O-rings in EPDM, ethylene propylene diene monomer, a compound with excellent heat, ozone and weather resistance. It is used across automotive, electronic and electrical industries, in daily necessities and sports equipment, in mechanised industrial equipment, and in wires, cables and high voltage and ultra high voltage insulation. Food grade EPDM is available for pharmaceutical and food processing applications.
Key Benefits
- Excellent heat, ozone and weather resistance for outdoor and exposed use
- Performs well in water, heating systems and brake fluid
- Resistant to coolants and refrigerants, which suits refrigeration units
- Food grade EPDM available for food and pharmaceutical processing
- Used in high voltage and ultra high voltage insulation applications
Problems It Solves
- Nitrile seals failing quickly in water, steam and brake fluid
- Seals perishing from ozone and weather exposure outdoors
- Non food grade compounds used in food contact applications
- Refrigerant attacking an unsuitable compound

Compared With The Alternatives
| NBR O-rings | EPDM excels in water, steam and brake fluid and is poor in mineral oil; nitrile is the reverse. Getting this the wrong way round is the most common sealing mistake. |
|---|---|
| Silicone seals | Silicone tolerates a wider temperature range and is very flexible; EPDM has better mechanical strength and better resistance to water and steam over time. |
Use Guide
- Never put EPDM in a mineral oil circuit
- Specify food grade compound where the seal contacts food or pharmaceutical product
- Use EPDM in preference to nitrile for outdoor and ozone exposed applications
- Check brake fluid compatibility is required before substituting any other compound
Questions
Questions Buyers Ask About This Product
What does EPDM stand for?
Ethylene Propylene Diene Monomer.
Where does EPDM perform best?
In water, steam, heating systems, brake fluid, coolants and refrigerants, and in outdoor applications thanks to its ozone and weather resistance.
Is a food grade version available?
Yes, food grade EPDM is used in pharmaceutical and food processing applications.
Can EPDM be used with mineral oil?
No. EPDM swells and fails in mineral oil; use nitrile or a fluoroelastomer instead.
Is EPDM used in electrical applications?
Yes, in wires, cables and high voltage and ultra high voltage insulation materials.
