Weather Resistance Performance
- UV & Ozone Resistance
EPDM rubber maintains its sealing properties when exposed to sunlight and ozone over long-term outdoor operation. The material structure helps reduce surface cracking and aging caused by environmental exposure.
- Resistance to Weather Changes
EPDM Flange Gaskets are designed for applications involving rain, humidity, and temperature fluctuations. The rubber compound maintains elasticity during repeated environmental changes, helping the gasket continue to fill the sealing gap between flange surfaces.
- Outdoor Sealing Stability
The gasket forms a compressed sealing layer between flange connections to reduce water penetration and external contamination. Proper material selection and compression design help maintain sealing contact during outdoor installation conditions.
Flange Compatibility
Metal & Equipment Flange Matching
EPDM Flange Gaskets can be manufactured to match different flange structures, including metal equipment flanges, stainless steel connections, and fabricated assemblies. Dimensions are selected according to the flange sealing surface and installation requirements.
Dimension Adaptation
The gasket size can be adjusted based on inner diameter, outer diameter, thickness, and flange geometry. Correct dimensional matching helps ensure the gasket is properly compressed after assembly.
Custom Sealing Profiles
For non-standard flange designs, Chaoyue can produce gasket profiles according to technical drawings or samples. Custom shapes, thicknesses, and sealing structures can be developed for specific equipment connections.
FAQ
What makes EPDM flange gaskets suitable for outdoor applications?
EPDM rubber provides resistance to UV exposure, ozone, rain, and humidity. These properties help the gasket maintain elasticity and sealing contact when installed in outdoor environments with continuous weather exposure.
What is the difference between waterproof and weatherproof EPDM flange gaskets?
Waterproof EPDM flange gaskets focus on preventing water leakage at the sealing interface, while weatherproof EPDM flange gaskets are designed for longer exposure to outdoor conditions such as sunlight, ozone, temperature changes, and weather aging.
Can EPDM flange gaskets be used for outdoor equipment exposed to sunlight?
Yes. EPDM is commonly selected for outdoor sealing applications because it has resistance to UV radiation and ozone, which helps reduce aging effects caused by long-term environmental exposure.
