What Are Extruded Rubber Bulb Seals and Gaskets?

Bulb Seals are flexible rubber components designed with a bulb-shaped sealing area that compresses to create a secure seal between two surfaces. The extruded design allows for precise dimensional control and customization based on specific application requirements. These seals are commonly used for:

• Weatherstripping
• Vibration Dampening
• Noise Reduction
• Shock Absorption

Bulb seals are highly versatile and can be designed in different sizes, profiles, and materials to meet various sealing needs. The bulb section offers flexible compression, while the attachment base provides a secure installation method, making these seals suitable for both static and dynamic applications.

Key Features and Benefits of Accuseal Rubber Bulb Seals and Gaskets

1. Superior Compression and Sealing Ability

One of the standout features of rubber bulb seals is their exceptional compression and recovery properties. The bulb portion easily compresses under pressure to create a snug, airtight seal that prevents the infiltration of water, dust, air, or noise. When pressure is relieved, the bulb returns to its original shape, ensuring long-term durability and reliable sealing performance.

2. Weather and Environmental Resistance

Accuseal Rubber Inc. produces weather-resistant bulb seals that are designed to withstand harsh environmental conditions. Whether you need protection from UV radiation, ozone, saltwater, or extreme temperatures, our bulb seals are manufactured from high-performance rubber materials, ensuring that they perform exceptionally well in both outdoor and indoor applications.

Materials used in our bulb seals include:

• EPDM Rubber: Known for its excellent weather, UV, and ozone resistance, perfect for outdoor sealing applications.
• Silicone Rubber: Withstands extreme temperature ranges, making it ideal for high-heat environments such as automotive or aerospace settings.
• Neoprene Rubber: Offers good chemical, oil, and weather resistance, making it suitable for industrial and marine applications.

3. Versatile and Customizable Designs

At Accuseal Rubber Inc., we understand that each application has unique requirements, which is why we offer customizable extrusion profiles for our bulb seals and gaskets. Whether you need a specific size, shape, or material, our extruded seals can be tailored to your exact specifications, ensuring a perfect fit and optimal sealing performance. We also offer various attachment options, including adhesive-backed, push-fit, and mechanical fastening designs, for easy installation.

4. Vibration Dampening and Noise Reduction

In addition to sealing, bulb seals provide excellent vibration dampening and noise reduction properties. The flexible rubber bulb absorbs mechanical vibrations, reducing wear and tear on equipment, and minimizing noise transmission. This makes them ideal for use in automotive, marine, and industrial machinery, where vibration control is critical for operational longevity and comfort.

5. Durable and Long-Lasting

Our bulb seals are engineered to provide long-lasting sealing solutions even in high-demand environments. The rubber compounds used in the manufacturing process are designed for durability, ensuring the seals maintain their integrity and sealing properties even after years of exposure to harsh conditions or repeated use.
