What Are EPDM Washers?
EPDM washers are non-metallic rubber washers designed to:
- Create weatherproof seals
- Prevent water ingress
- Reduce vibration
- Protect surfaces
- Compensate for irregular surfaces
- Provide spacing and cushioning
Their resistance to environmental exposure makes them one of the most commonly specified rubber washer materials for outdoor use.
Why Choose EPDM Washers?
EPDM offers several performance advantages over many other elastomers.
Exceptional Weather Resistance
EPDM performs extremely well when exposed to:
- Rain
- Snow
- Frost
- UV radiation
- Ozone
- Outdoor environments
This makes it one of the preferred materials for long-term external applications.
Excellent Water Resistance
EPDM washers provide reliable performance in:
- Water treatment systems
- Roofing systems
- Plumbing installations
- External equipment
Long Service Life
EPDM resists cracking, hardening and degradation caused by environmental exposure.
Flexible Sealing Performance
The material compresses effectively to help create reliable seals.
