Bulb Seals for Maximum Sealing Power

Bulb Seals are designed to track into a channel and fill a void or gap, creating a seal. They consist of a mounting mechanism and a bulb section that does the actual sealing.

Depending on the intended application and surrounding conditions, many different materials can be used. But no matter the material, our manufacturing processes yield a strong, durable bulb seal that stays in place and delivers reliable sealing power.

Bulb Seal Applications

Bulb seals are most commonly used around doors, windows, and hatches to provide sealing and insulation. This gives them their alternate name, “trim seals.” They are also sometimes used in industrial mixing and processing applications in which water, dust, or extreme heat need to be sealed off and contained to a specific area or vessel.

  • Automotive - Vehicles are exposed to the elements, and bulb seals can be used to seal off key components to protect the interior.
  • Residential - Bulb seals are often used as weatherstripping around doors and windows.
  • Process Industries - The pharmaceutical and food processing industries often use bulb seals to seal the doors and hatches of industrial mixing and drying equipment.
