A car’s air conditioning system is complex, with a multitude of O-Ring's running throughout the pressure lines to and from a belt-driven/electric compressor. Every connection point needs to be sealed in order to ensure optimum performance.
Requirements for sealing air conditioning systems
Custom-designed engineered molded components can incorporate multiple parts into a single product, allowing placement into the limited space available in air conditioning systems. Materials engineered to prevent stick-slip, extend seal and system life where air conditioning use is limited.
O-Ring , special PTFE rotary seals
The battery provides the power to a number of critical systems in the car and without it, the vehicle is inoperable. Start-stop options as well as hybrid powertrains to minimize emissions, have challenging impacts on new battery technologies. Drivers expect to start their car whatever the weather, first time, every time. For that kind of operational dependability, reliable sealing and battery venting is needed.
Requirements for sealing batteries
Ventseal is specially designed for locked container applications such as batteries. It combines a seal and pressure relief function all in one product.
Probably the most safety critical of all automotive applications , it is vital that when needed the brakes will activate instantaneously.
Requirements for sealing brakes
The drivetrain and transmission of a vehicle adapts the output of an engine to the drive wheels. Engines operate at relatively high rotational speeds and the transmission reduces that speed to the slower wheel speed, increasing torque in the process.
Requirements for Sealing of Transmission
Complex sealing configurations combine a number of advanced seals that seal in lubricants, prevent ingress of external media and provide maximum performance in rotary applications due to unrivaled low friction.

Sophisticated electronics that control key functions of the car are housed in the metal/plastic box of an ECU. Often situated in the engine compartment or other areas subject to environmental conditions, good sealing is vital as failure is not an option.
Requirements for Sealing of ECUs
The Rubore® Cover Seal integrates the seal and ECU cover into one single unit, thereby eliminating costly manual installation. This results in a perfect solution at a reduced cost.
In addition, integrating the ECU cover and the seal, as seen with the Rubore® Cover Seal, reduces the number of parts therefore minimizing logistics, assembly and administration costs. Full elastomer gaskets are also available for a wide variety of applications. In-house testing of permeation is available.
Engineered Molded Components , Rubore® Seals ,O-Rings
Running at extreme temperatures and high pressures, secure and reliable sealing is required throughout the fuelling system – in the fuel injectors, the common rail system, the fuel lines and fuel tank.
Requirements for sealing the fuel system
Optimized performance for efficient engine operation
A wide range of seals are available for the different sealing environments within the fuel system. They are composed of specialized materials that have been engineered to withstand gasoline, diesel and bio-fuels, as well as temperature and pressure extremes.

Trelleborg Sealing Solutions has developed a fluoroelastomer sealing compound for fuel injection applications that performs at extremely low temperatures
The objective of ride control systems is to combine steering stability with good handling characteristics while maximizing passenger comfort. The ride control system incorporates the suspension system and shock absorbers.
Requirements for sealing ride control
Today's cars include a wide range of safety solutions to protect drivers and passengers from various types of collisions. This includes airbags installed to surround the front and rear seats.

Trelleborg Sealing Solutions uses its capabilities in liquid silicone rubber injection molding technology to produce safety critical components, completely flash-less, in a clean and fully automated process.
Engines operate at high temperatures and to maximize life of certain engine components, the engine needs to be cooled using fluid that flows through the radiator.
Requirements for sealing engine cooling systems
Specialized seals manufactured using the Rubore® Seal technology or standard full elastomer gaskets, provide custom-made solutions with an extended seal life.
