EPDM Flange Gaskets
An EPDM flange gasket is a flexible gasket made of ethylene propylene rubber, resistant to water, hot water, air and mild chemicals. Being resistant to ozone and weather, it works for a long time without ageing on outdoor lines too.
A similar manufacturer datasheet gives −50 °C to +150 °C for EPDM seals. It is used on water mains, heating-cooling circuits and low-pressure steam lines; it is not suitable for oil and fuel lines.
Main Applications
- Drinking and service water lines
- Heating and cooling circuits
- Low-pressure steam and condensate
- Compressed air lines
- Outdoor and roof lines
Technical Data
| Material | EPDM (ethylene propylene rubber) |
|---|---|
| Temperature | −50 °C … +150 °C (similar manufacturer datasheet) |
| Type | Flat rubber gasket |
| Thickness | By model |
| Dimension standard | EN 1514-1 |
| Medium | Water, hot water, air, mild chemicals |
| Not suited | Mineral oil and fuel |
Material Options
| Part | EPDM gasket | NBR gasket |
|---|---|---|
| Material | Ethylene propylene rubber | Nitrile rubber |
| Water and steam | Suitable | Limited |
| Oil and fuel | Not suitable | Suitable |
| Ozone resistance | High | Low |
Which material? EPDM swells and degrades in contact with mineral oil and fuel; use NBR or FKM gaskets for oily media. The temperature limit is from a similar datasheet and is confirmed with the product datasheet.
