Automotive

The automotive industry makes particularly exacting demands on its suppliers. Constant pressures to innovate, for instance due to new legal requirements and changing customer wishes paired with the highest quality requirements and high cost pressures, result in a challenging field in Parker Prädifa has been successfully operating for decades.


Numerous Parker products have proven their viability in practically all production vehicles around the globe in a great diversity of applications ranging from fuel tanks to sun roofs. We manufacture our products at worldwide IATF 16949 certified locations, produce our own elastomer compounds and perform 100% inspections even of complex components using testing machines specifically developed for this purpose.
Experienced project and development engineers support our customers from the initial product idea through to production launch. Please contact us concerning your special requirements.

    Fuel System

    The fuel supply system involves several components from the fuel pump in the tank through to the injection system. Resistance against an increasingly wide range of fuels, good barrier properties and very good mechanical characteristics are key criteria for the selection of seals. Products such as O-rings and elastomer moldings or plastic parts from Parker Prädifa are used in all components that come into contact with fuel.

    Drivetrain

    The power output of the engine is transmitted to the wheels by the drivetrain with all of its components. In the case of a conventional internal combustion engine (IC engine), the drivetrain consists of the clutch, the manually shifted transmission and the drive shaft as its main components.

    Battery and Hybrid Electric Drive

    There are various concepts of hybrid electric drive systems, e.g. plug-in hybrids which additionally offer the opportunity to charge the batteries by plugging them directly into a power outlet. Today’s battery electric vehicles almost exclusively use lithium-ion batteries in the cells of which substances such as solvents, conductive salts and additives in various combinations store the electricity. In this aggressive environment, seals also have to be resistant against highly toxic hydrofluoric acid.

    Emission Control - SCR and AdBlue®

    The growing pressure to reduce exhaust emissions, above all the greenhouse gas CO2 and nitrogen oxides that are harmful to human health, poses great challenges to the automotive industry. In the context of lowering harmful nitrogen oxides particularly in the emissions of diesel engines SCR (selective catalytic reduction) technology plays an important role.

    Diesel Common Rail

    The use of common rail injection systems, aka accumulator injection systems, has become standard practice in diesel technology today. Due to the required enhancement of energy efficiency, there is a trend toward increasingly high injection pressures. Accordingly, sealing elements and sealing systems for pumps and injectors have to ensure operating pressures of up to 2,800 bar. In addition to media compatibility and pressure resistance, sealing elements of injectors particularly have to exhibit high temperature resistance due to their proximity to the combustion chamber.
