Description
Bonded EPDM Black Washers are highly effective sealing components commonly used in a variety of industrial, automotive, plumbing, and electrical applications. They combine a durable metal washer with an EPDM (Ethylene Propylene Diene Monomer) rubber seal, providing excellent performance in harsh environments. Here’s a detailed breakdown of the product:
Key Features of Bonded EPDM Black Washers:
- Material Composition:
- Metal Washer: Provides the structural strength and durability required for securing components.
- EPDM Rubber: Offers superior sealing properties, protecting against weathering, UV, ozone, and extreme temperature fluctuations.
- Color:
- The EPDM rubber is typically black, which is standard for EPDM due to its natural properties, including the addition of carbon black for enhanced UV resistance.
- Temperature Resistance:
- EPDM rubber can withstand temperatures ranging from -40°C to +120°C (or higher, depending on the formulation).
- Chemical Resistance:
- Water, steam, mild acids, alkalis, and polar solvents are easily resisted.
- Not suitable for petroleum-based oils, fuels, or strong acids.
- Applications:
- Automotive: Ideal for engine, transmission, and fluid systems.
- Plumbing and HVAC: Used in water or gas systems to prevent leaks.
- Electrical Enclosures: Seals electrical connections to prevent moisture ingress.
- Industrial Machinery: Useful in equipment exposed to vibration or extreme conditions.
Advantages of Bonded EPDM Black Washers:
- Vibration Resistance: The bonded design of these washers keeps the rubber in place, even under vibrations or movement.
- Longevity: EPDM is highly resistant to aging, cracking, and degradation, ensuring a long lifespan.
- Weather Resistance: Excellent performance in outdoor or harsh environments, resisting the effects of UV and ozone exposure.
- Easy Installation: By combining the benefits of both a metal washer and a rubber seal, installation is simplified.
Common Sizes and Specifications:
Bonded EPDM washers are available in various sizes to fit different bolt diameters and specific application requirements. Some common specifications include:
- Inner Diameter (ID): Matches the bolt or screw size to create a tight, secure fit.
- Outer Diameter (OD): Determines the sealing surface area for the washer.
- Thickness: Varies based on the application needs, providing the right balance between sealing effectiveness and durability.
Typical Applications:
- Automotive:
- Sealing bolts in engines, transmissions, and fluid systems.
- Preventing leaks in components such as water pumps, radiators, and fuel systems.
- Plumbing:
- Sealing pipe connections and fittings to avoid leaks.
- Essential in water or gas systems for secure, leak-free connections.
- Electrical:
- Used for sealing electrical enclosures and connections, ensuring protection against moisture and dust ingress.
- Industrial:
- Ideal for machinery and equipment that experience vibration, thermal cycling, or are exposed to harsh environmental conditions.
Why Choose EPDM?
- Durability & Versatility: EPDM is one of the most durable and versatile elastomers, ideal for sealing in high and low temperature environments.
- UV & Ozone Resistance: The black color of the rubber provides additional UV and ozone resistance, making it a preferred choice for outdoor applications.
- Wide Application Range: EPDM is highly suited for applications involving water, air, and dust sealing due to its superior performenc
