Bruss

What Bruss does

BRUSS Sealing Systems GmbH, headquartered in Hoisdorf, Germany, is a privately held, family-run developer and manufacturer of high-end sealing systems for automotive powertrains. Founded in 1957, the company employs approximately 2,400 people and operates eight wholly-owned production and development sites across Germany, Spain, Ireland, Poland, the United States and China, supplying sealing solutions into both internal combustion and electric vehicle programs of major automotive OEMs and tier-1 suppliers.

The company's product portfolio spans dynamic seals (radial rotary shaft seals, cassettes, and the trademarked IWDR/IWDS integrated modules with speed detection), static seals (O-rings and profiled elastomer-metal composites), high-precision injection-molded plastic parts, complex modules and assemblies (cylinder head covers, oil modules with integrated FLAPS oil mist separation, DRV valves), the proprietary ILSP composite piston for automatic transmissions, multipole magnetizable-elastomer encoders for rotational sensing, current-carrying busbars and grounding rings for EV power distribution, and valves including battery vent and coolant distributor types. Core differentiating technologies include the F-LESS springless rotary shaft seal, integrated module sealing concepts, a patented busbar sealing process that prevents micro-gaps after aging, and full in-house PTFE and elastomer-compound production.

BRUSS generates revenue through long-term B2B supply contracts with automotive OEMs and tier-1 suppliers, sold via direct field-sales teams under a co-development model that runs from concept through series production. Vertical integration across elastomer compounding, PTFE pressing and sintering, tool construction, injection molding, surface technology and module assembly gives the firm control over cost, quality and lead time. The company is IATF 16949 certified at all automotive-direct plants and additionally maintains ISO 14001, ISO 45001 and ISO 50001 certifications, with stated use of renewable electricity at suitable sites. Andreas Rapp and Carlo Crosetto serve as Managing Directors.

Products and services

• Dynamic Seals (Dynamische Dichtungen) Dynamic shaft seals for automotive drivetrains, including radial rotary shaft seals (RWDR), cassettes, and integrated IWDR/IWDS modules with speed detection, offered in elastomer materials (ACM, FKM, HNBR) and PTFE for shaft diameters 9mm to 150mm, speeds up to 22,000 rpm, and temperature range -40C to +150C. Designed for automotive OEMs and tier-1 drivetrain suppliers.
• Static Seals (Statische Dichtungen) Static sealing components for automotive and industrial applications, including O-rings and profiled sealing rings available as pure elastomer parts, elastomer-metal composites, and connecting elements. Used by OEMs and tier-1 suppliers in drivetrains and modules.
• High-Precision Injection Molded Parts (Hochpräzise Spritzgussteile) Precision plastic injection molded parts for automotive applications, part weights from 0.1g to 200g, including composite and automation solutions such as hot riveting and ultrasonic welding. Targets automotive customers needing precision plastic components.
• Modules & Complex Assemblies (Module & komplexe Baugruppen) Complex assembled modules for automotive drivetrains, including cylinder head covers, oil pans, oil modules, and thermal management modules that integrate sealing, oil mist separation (FLAPS), pressure control (DRV/PCV valves), and flow control functions into a single delivered assembly. Used by OEMs and tier-1 suppliers.
• Multipole Technology (Multipoltechnologie) Magnetizable elastomer encoders that enable precise measurement of rotational speed and angular changes of shafts, used in engines, transmissions, steering, ABS systems, electric motors, and machine tools.
