Product Highlight: Bulb Seal

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.
