Description
Bonded washers with EPDM (black) are specialized sealing components that combine a metal washer (typically stainless steel, carbon steel, or other metals) with a black EPDM rubber sea These washers are designed to create a reliable, vibration-resistant seal in applications where protection against water, air, dust, or other environmental factors is required.
Key Features of Bonded EPDM Black Washers:
1. Material Composition
Metal Washer Provides structural strength and durability.
-EPDM Rubber: Offers excellent sealing properties and resistance to weathering, UV, ozone, and temperature extremes.
2. Color The EPDM rubber is black, which is the standard color for EPDM due to its natural properties and added carbon black for UV resistance.
3. Temperature Resistance
– EPDM can withstand temperatures ranging from 40°C to +120°C (or higher, depending on the formulation).
4. Chemical Resistance
– Resistant to water, steam, mild acids, alkalis, and polar solvents.
– Not suitable for petroleum-based oils, fuels, or strong acids.
5. Applications
– Automotive (engine, transmission, and fluid systems).
– Plumbing and HVAC systems.
– Electrical enclosures and connections.
– Industrial machinery and equipment.
Advantages of Bonded EPDM Black Washers:
– Vibration Resistance: The bonded design ensures the rubber stays in place, even under vibration or movement.
– Longevity**: EPDM is highly resistant to aging, cracking, and degradation.
-Weather Resistance: Excellent performance in outdoor or harsh environments.
-Easy Installation**: Combines the benefits of a metal washer and a rubber seal in one component.
Common Sizes and Specifications:
Bonded EPDM washers are available in various sizes to fit different bolt diameters and application requirements. Key specifications include:
– Inner Diameter (ID) Matches the bolt or screw size.
– Outer Diameter (OD) Determines the sealing surface area.
– Thickness : Varies based on the application needs.
Typical Applications:
1. Automotive
– Sealing bolts in engines, transmissions, and fluid systems.
– Protecting against leaks in water pumps, radiators, and fuel systems.
2. Plumbing:
– Sealing pipe connections and fittings.
– Preventing leaks in water or gas systems.
3.Electrical
– Sealing electrical enclosures or connections to prevent moisture ingress.
4. Industrial
– Machinery and equipment exposed to vibration, thermal cycling, or harsh environments.
Why Choose EPDM
– EPDM is one of the most durable and versatile elastomers for sealing applications.
– It performs well in both high and low-temperature environments.
– Its black color provides added UV and ozone resistance, making it ideal for outdoor use.
