Double Bulb Seal Profile

Key Features

Superior Seal Integrity
Versatility in Applications
Enhanced Compression Rates
Improved Insulation

A Double Bulb Seal Profile in rubber extrusion has two bulb-shaped sections, enhancing sealing performance.

Double bulb seals excel in rubber extrusion, featuring a distinctive dual-bulb design. They deliver superior performance across diverse applications, from automotive to industrial settings. The seals’ adaptability and efficiency make them a reliable choice for enhanced sealing capabilities. The presence of two bulb sections allows for higher compression rates, ideal for applications requiring a robust and enduring seal, ensuring long-lasting effectiveness in dynamic environments.

Double bulb seals provide a superior seal against external elements, excelling in preventing air, water, dust, and noise infiltration. The dual-bulb configuration grants them adaptability to various surfaces, suitable for diverse applications like automotive doors, industrial enclosures, or construction windows, offering a secure and effective sealing solution.
