Automotive Applications

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.

O-Rings

Probably the most safety critical of all automotive applications , it is vital that when needed the brakes will activate instantaneously.


Our Solutions


O-Ring, Custom-molded components

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.


Our Solutions


Rotary Shaft Seals, Roto L, Hydraulic Wear Rings, Back-up Ring, O-Rings

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.


Our Solutions


O-Rings, Engineered Molded Components

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.
