EPDM Rubber Gaskets

As part of our comprehensive range of rubber gaskets, here at Martin’s Rubber we offer a selection of EPDM gaskets, including a range of punched, cut, extruded, sheet and fabricated products.

What is an EPDM rubber gasket?

TEPDM Rubber Gasketshe main function of an EPDM rubber gasket is to fill the space between two or more surfaces in order to adequately prevent any seepage from or into objects. EPDM rubber gaskets are also used to fill irregularities or gaps between machine parts in order to increase the lifespan of machinery. EPDM gaskets are well-known for their excellent weathering resistance. Coupled with outstanding UV and ozone resistance properties and the ability to withstand high temperatures, EPDM (Ethylene Propylene Diene Monomer) has excellent weathering properties and is therefore ideal for use outdoors, where it will be exposed to the elements.

EPDM gasket specification

EPDM gaskets are available in a medium to high volume quantity and can be offered in WRAS approved grades, so that the gaskets are suitable for use with potable water. Some of the characteristics that make EPDM rubber gaskets such a multi-purpose and versatile gasket material include:

  • Excellent resistance to ozone, sunlight, aging, severe weather conditions, oxygen, acids, alkalis, oils, grease, ketones and ethanol
  • Outstanding colour stability
  • Odour-free characteristics
  • High temperature resistance
  • Insulating qualities

EPDM gaskets temperature rating

EPDM gaskets are recognised for their particularly high temperature rating. This level of tolerance makes EPDM rubber gaskets the ideal choice when it comes to environments in which temperatures may exceed 100°C. In fact, with EPDM gaskets, much higher temperature ratings are achievable with a specially formulated compound, so if your specific project requires a durable gasket that can withstand such high temperatures, an EPDM gasket may be the ideal rubber gasket for you.

EPDM gasket chemical resistance

Due to the high chemical resistance of an EPDM gasket, it is often recommended for use in environments whereby the following media are likely to be present:

  • Phosphate ester based hydraulic fluids
  • Steam and water
  • Silicone oils and greases
  • Dilute acids and alkalis
  • Ketones
  • Alcohol

Although an EPDM gasket’s chemical resistance is very high, we would advise against using EPDM rubber gaskets with certain media, such as petroleum oils, and would recommend using alternative gasket materials, like nitrile gaskets, which work particularly well in such applications.

EPDM rubber gasket applications

Given that EPDM rubber gaskets are resistant to water, ageing and ozone, they are ideal for use in a number of exposed and exterior applications. EPDM rubber gaskets are often accepted as being a great all-round, general-purpose gasket and for this reason, it can be found in many medium-range applications, such as:

  • Low pressure pipe seals
  • Weather strips in outdoor applications
  • Man way gasket
