Rubber Seals and O-Rings
EPDM Seals and O-Rings
EPDM seals and O-rings, chosen for heat, ozone and weather resistance.
Product Overview
EPDM seals and O-rings, chosen for heat, ozone and weather resistance. EPDM is used across automotive, electronic and electrical industries, daily necessities, sports equipment and mechanised industrial equipment, and as insulation material for wires, cables and high-voltage and ultra-high-voltage applications. In sealing it covers heating systems, automotive brakes, water systems and refrigeration units, and food-grade EPDM extends it to pharmaceutical and food processing.
Key benefits
Why Buyers Choose This Specification
Weather and Ozone Resistance
EPDM does not crack in sunlight and ozone the way nitrile does. For any seal that lives outdoors or near electrical equipment, that is the property that decides service life.
The Right Choice for Water and Steam
Heating systems, water systems and refrigeration units all use EPDM because it handles hot water, steam and glycol where oil-resistant elastomers fail.
Brake Fluid Compatible
Automotive brake systems are a named application. Brake fluid attacks most elastomers, and EPDM is one of the few that tolerates it.
Food Grade Available
With food-grade EPDM the same material covers pharmaceutical and food processing, which keeps one elastomer family across a plant.
Application scenarios
Where It Is Used
- Heating system seals handling hot water and steam
- Automotive brake system sealing
- Water systems and plumbing seals
- Refrigeration units, due to resistance to coolants and refrigerants
- Pharmaceutical and food processing using food-grade EPDM
- High-voltage and ultra-high-voltage insulation components
Who it is for
The Buyers This Product Suits
HVAC and Refrigeration Manufacturers
Resistance to coolants and refrigerants is the reason EPDM is specified in refrigeration units.
Automotive Brake System Suppliers
Brake fluid compatibility rules out most elastomers, and EPDM is a named material for this duty.
Food and Pharmaceutical Processors
Food-grade EPDM covers both sectors where water, steam and cleaning chemistry dominate.
Problems it solves
What It Fixes
Seals Cracking in Sunlight and Ozone
EPDM's weather and ozone resistance is what prevents the surface cracking that destroys nitrile outdoors.
Seals Failing in Hot Water and Steam
Heat resistance combined with water compatibility is exactly what EPDM provides and oil-resistant elastomers do not.
Brake Fluid Attacking the Seal
EPDM is the standard elastomer for automotive brake applications for this reason.

Sourcing And Inspection
This product is supplied through TrueGlow Imaging, working with manufacturing partners whose facilities are visited and verified rather than taken on trust. In-process quality control and delivery supervision are available so goods are inspected before the container is sealed. Certifications quoted on this page are those stated on the product specification and belong to that product range rather than to our trading entity, so ask for the certificate covering your specific item.
Handling guide
Getting It Right First Time
Step 1
Never use EPDM with petroleum oils, fuels or mineral-oil hydraulic fluid.
Step 2
Specify food-grade EPDM for pharmaceutical and food processing duty.
Step 3
Confirm the operating temperature and the fluid together before selecting.
Step 4
Measure inside diameter and cross-section for replacement O-rings.
Step 5
Store away from direct sunlight even though EPDM resists ozone well.
Comparison
How It Compares In Our Range
EPDM against the oil-resistant elastomers.
| EPDM | Excellent heat, ozone and weather resistance, and compatible with water, steam, glycol, refrigerants and brake fluid. Not compatible with petroleum oils. |
|---|---|
| NBR | Good oil, fuel and hydrocarbon resistance, but poor ozone and weather resistance and unsuitable for brake fluid. |

Selecting an O-Ring Material NBR EPDM FKM or FFKM
Almost every seal failure is a material selection error rather than a dimensional one. The fluid and the temperature decide the elastomer, and the size is the easy part.
