Seals for battery housing and service lids The high-voltage battery needs special protection. Trelleborg offers individualized sealing solutions to fit many different lid and battery case geometries. These enable inexpensive and fully automated assembly and simplify disassembly when the battery is serviced.
• For aluminum, steel and plastic housings
• Tightness according to IPX9K and IPX7, and flammability compliant with UL94 V0 and HB
• Special seal design enables thin-walled lid and reduces number of screws required
Seals for high voltage connectors
Special products provide tolerance compensation between plastic and metal housing, combining two or three dissimilar materials, including rubbers, metals and plastics, tailored
to the application. Seals produced comply with flammability requirements UL94 V0 & HB and provide electrical insulation.
A HiSpin™ PDR RT rotary seal has a new type of PTFE sealing lip that delivers minimal frictional torque with high static and dynamic tightness. Sealing is independent of the direction of travel at high speeds of more than 60 m/s /134 mph, while combining grounding into the same product through innovative conductive materials.
Many applications within the fuel cell system require gas tightness at low temperatures and high pressures. Newly developed PU and FKM materials, specially formulated for these applications, combined with our established seal designs provide the ideal solutions. These low temperature compounds solve known issues with the typical glass transition point shift.

Direct liquid cooling is an innovative solution for higher power densities and more compact modules. Pressure activated profile seals guarantee safe and efficient sealing for the power electronics. A narrow seal design increases the cooling surface, giving increased performance.
Multifunctional components combine sealing and housing functions, reduce critical interfaces and lower total system cost. Multicomponent parts can be manufactured from different material combinations, such as LSR, PA66, steel, PPA, EPDM and many more.
Thermal management is essential for sensitive electric systems. Heat dissipation and protection from cold temperatures is a challenge when controlling liquid flow paths. Trelleborg Sealing Solutions offers individualized solutions for critical sealing of three-, four- or five-way thermal management control valves, coolant proportional valves and electric coolant pumps. Multicomponent solutions make assembly easier, reduce installation space and deliver low torque, long-life sealing with during dynamic movement of ball valves.
