When a gasket fails in a water system, process pipeline, or HVAC installation, the consequences are immediate. Choosing the right material from the start can help you prevent unplanned downtime, rework, and potential contamination.
EPDM (Ethylene Propylene Diene Monomer) is one of the most widely specified rubber compounds in the Australian industry. It handles water, steam, mild acids, alkalis, and sustained UV and ozone exposure without degrading its seal.
At Industrial Experts, we supply a full range of EPDM rubber gaskets for standard flange sizes and custom requirements, backed by over 20 years of manufacturing experience. We’re a trusted EPDM gasket supplier that stocks the right sizes, cuts to order, and delivers fast.

Key Features & Benefits
- UV & Ozone Resistance: Maintains seal integrity in outdoor and exposed environments without cracking or degrading.
- Temperature Range: Flexible and reliable from -30°C to +100°C.
- Water & Steam Resistance: Ideal for water infrastructure, hot water services, and low-pressure steam lines.
- Chemical Compatibility: Resists mild acids, alkalis, and cleaning agents common across food, water, and processing applications.
- Oil and Fuel Limitations: EPDM is not suitable for petroleum-based oils or fuels. Nitrile or Viton may be more appropriate for these applications.
- Compression Set Resistance: Holds its form under sustained load, reducing the risk of seal failure over time.
- AS 4020 Compliance: Potable water-approved EPDM available for drinking water infrastructure.

An EPDM gasket is the most commonly specified rubber gasket material for Australian water infrastructure, largely due to its compliance with AS 4020 for potable water and its resistance to chlorinated water and mild chemical dosing.
When your application calls for a different material, our broader range of industrial gaskets includes paper gaskets for lower-pressure pipework and our spiral wound gasket range for high-temperature, high-pressure environments.
Types of EPDM Gaskets We Supply
Full Face EPDM Gaskets
Full-face gaskets cover the entire flange face, including the bolt holes. Suited to flat face (FF) flanges in low- to medium-pressure water and process systems.
Ring Face EPDM Gaskets
Sit inside the bolt circle for raised face (RF) flanges. A compact, material-efficient option for non-aggressive media.
Custom EPDM Gaskets
Our custom gaskets service produces custom EPDM gaskets to ±0.1mm precision using CNC oscillating knife cutting, in thicknesses from 0.5mm to 50mm and diameters up to 1600mm. Send us a drawing, CAD file, or a worn sample, and our team can confirm the material, dimensions, and production requirements.
EPDM Sheet & Foam Products
Prefer to cut your own seals in-house? Our EPDM sheet is available across a wide range of thicknesses. Our EPDM foam tape is suitable for compression sealing and gap insulation applications.
Advantages of EPDM Rubber
- Weathering Resistance: Performs consistently outdoors, with no UV or ozone degradation.
- Potable Water Compliance: AS 4020-approved grades available for water infrastructure.
- Flexibility: Remains pliable and seals reliably across a broad temperature range.
- Food-Grade Options: White EPDM meets FDA standards for food and beverage processing.
- Long Service Life: Low compression set means sustained sealing performance over time.
