At Elbex, our team produces a wide range of custom and standard rubber extrusions to fill needs in many different industries. Among these are bulb seals, which help provide maximum sealing power in an application. Here’s what you should know.
What is a Bulb Seal?
A bulb seal is actually comprised of two parts: a mounting mechanism and the bulb section, which tracks into a channel to fill voids or gaps. Bulb seals are also sometimes called trim seals because they are frequently used around doors and windows. A variety of materials can be used to manufacture bulb seals based on their operating environment and intended application to ensure they meet performance requirements.
Common Bulb Seal Applications
As previously noted, bulb seals are most often used to seal and insulate doors, hatches, and windows. This is especially common in residential construction, where bulb seals are used for weatherstripping. They are also used to seal off interior components in automobiles to protect them from water, dust, and other contaminants. Bulb seals are also used for doors and hatches for industrial mixing and drying equipment in pharmaceutical and food processing facilities. Their ability to effectively block water, contaminants, and extreme temperatures is vital in these processes.

In industries like mass transit and construction, secure fitting and protected edges are key to the durability and safety of many applications. Rubber extrusions, particularly custom extruded u-channels and variations like ribbed rubber channels can play an essential role in these areas – and Elbex’s expertise in providing custom solutions will help you move forward with confidence. Understanding U-Channel Rubber Extrusions U-channel rubber extrusions are named for their distinctive U-shape, which allows them to fit over edges or within channels on mating pieces to ensure a secure fit and protect edges. The size and thickness of the legs and base should be adapted to the needs of the application, since precise dimensions are needed to get a secure fit. Depending on needs, extra features like ribbed rubber channels can be added for increased grip, vibration dampening, or sealing. As with other rubber extrusions, various materials, such as EPDM, neoprene, or silicone can be used for U-channels. The right material depends on the application’s environmental conditions (like temperature, chemicals, and UV exposure), as well as performance requirements such as flexibility and durability. Diverse Applications Across Industries U-channels serve a variety of important functions. They can be used as edge guards to protect surfaces from damage and provide a finished look, such as in automotive door edges, metal paneling, or machinery housings. The tight fit of these rubber extrusions within the channel also dampens vibrations and prevents unwanted movement between components. This is especially important for preventing excess wear and promoting structural integrity in transportation equipment and other machinery. U-channels are also used to create seals against dust, moisture, and other environmental elements. Weatherstripping in homes and glazing seals on building and automotive systems are common examples of this. With the right materials, U-channels can provide essential protection, even in extreme environments that undergo frequent temperature changes.
