In terms of performance, extension drill rods must be used with care
Another advantage of tapered drill bits is their versatility
Common causes of oil seal failure

Power steering oil seals are integral to the functionality of the vehicle's power steering system. These seals are responsible for containing the hydraulic fluid within the power steering mechanism, preventing leaks and maintaining the smooth operation of the steering components. Power steering oil seals contribute to the proper functioning and longevity of the steering system, ensuring precise and responsive vehicle control.
Oil seals, also known as shaft seals, are radial lip type seals which are primarily used for retaining lubricants in equipment having rotating, reciprocating or oscillating shafts. The rotating shaft application is most common.

Conventional oil is the most commonly used type of oil. It is ideal for light-duty, late-model cars with low to average mileage and a simple engine design.
By first finding out the dimensions of the inner and outer diameters and the height of the bore, you have all the data for the correct size of the oil seal. Of course, the oil seal must also be able to withstand the pressure, temperature and medium it is exposed to within the seal during the manufacturing process. You can read more about this in our oil seal selection guide.
The sealing lip of the RST-D is more heavy-duty, so it can cope with pressures of up to 10 bar at slightly lower rotation speeds.
Our suppliers try to provide the best quality oil seals and products are in some cases optimised to improve performance and fitment. Corteco is one of these brands, whose case studies we have listed for you.
