What Are Extruded Rubber Double-Bulb Seals?

Double-bulb seals consist of two compressible bulb-like structures that provide a higher level of sealing performance than single-bulb designs. These seals are engineered to compress easily under pressure and return to their original shape when the pressure is released. The dual-bulb design offers:

• Enhanced Sealing Power: Two bulbs create additional points of contact, ensuring better sealing and compression.
• Greater Flexibility: The flexible structure of the bulbs allows for superior sealing in uneven or complex surfaces.
• Increased Durability: The dual structure provides enhanced resistance to wear and tear in high-pressure applications.

These seals are used in applications that require an extra layer of protection, where standard seals may not be sufficient.

Key Features and Benefits of Accuseal Rubber Double-Bulb Seals

1. Dual Compression Zones for Superior Sealing

The key advantage of double-bulb seals is the dual compression zones, which provide additional sealing points for enhanced performance. These seals compress around gaps or joints, forming an airtight and watertight seal while maintaining excellent recovery properties. This makes them ideal for applications where extra protection against dust, water, air, and noise is essential.

2. Versatility and Adaptability

Accuseal Rubber’s double-bulb seals can be extruded in a variety of materials, profiles, and sizes to suit specific applications. Whether you need seals for low-pressure or high-pressure environments, we can tailor them to meet your exact needs. Our double-bulb seals are widely used in a range of industries, from automotive weatherstripping to industrial enclosure seals.

3. Resistance to Environmental Factors

Double-bulb seals are designed to provide long-lasting resistance to various environmental conditions. Whether it’s exposure to sunlight, ozone, extreme temperatures, or harsh chemicals, our seals maintain their structural integrity and performance. The materials used, such as EPDM, neoprene, and silicone, are selected for their resilience and durability in different environments:

• EPDM Rubber: Outstanding UV, ozone, and weather resistance, suitable for outdoor applications.
• Neoprene Rubber: Good resistance to oil, chemicals, and weathering.
• Silicone Rubber: Excellent thermal stability, performing well in high and low-temperature environments.

4. Shock Absorption and Vibration Dampening

Double-bulb seals are excellent at absorbing vibrations and dampening shocks, protecting equipment from wear and minimizing noise transmission. This feature is critical in applications such as automotive, heavy machinery, and marine environments, where vibration control is essential for smooth operation and longer component lifespan.

5. Customizable Designs for Various Applications

At Accuseal Rubber Inc., we offer customized extruded double-bulb seals based on your specific application requirements. Whether you need a unique profile, size, or material composition, our manufacturing capabilities allow us to design a seal that fits perfectly in your application. We can also provide a range of mounting options, including adhesive-backed or push-fit designs for ease of installation.

Applications of Double-Bulb Seals and Gaskets
