J: Additional code is added here as an identifier when two or more seals have exactly the same type codes and dimensional numbers.
In conclusion, choosing the right spark plugs for your MK7 GTI is crucial for optimal performance and engine efficiency. Upgrading to high-quality spark plugs can improve throttle response, fuel efficiency, and overall engine performance. Brands like NGK, Bosch, and Denso offer a variety of spark plugs that are specifically designed for performance cars like the MK7 GTI. When choosing spark plugs, consider factors like heat range and electrode material to ensure you're getting the best performance out of your MK7 GTI.
Auto parts oil seals play a crucial role in the proper functioning and maintenance of vehicle systems. These seals are designed to prevent the leakage of lubricating oil and the ingress of contaminants, ensuring the integrity and efficiency of various components within the vehicle. From wheel hub oil seals to steering oil seals, these components are essential for the smooth operation and longevity of automotive systems.
The simplest way is to know either the preferred manufacturers part number, the overall sizes of shaft diameter, housing diameter and bore depth, or use our brochure to establish the M Barnwell Services ordering reference. Many of the old traditional names of seal manufacturers have either changed or disappeared in this age of “acquisitions”. If no longer available, we will advise you and offer a suitable alternative seal, from stock whenever possible. If your concern is getting the right seals for the job, you will need to know something about the application as well as the overall sizes. If you have any doubts – contact us, we will help in your seal selection.
Does it mean the seal stops the leakage completely? Well, on the practical grounds yes because there is no ‘visible leakage’.
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.
Requirements of the shaft
Even more important than a correct interference fit of the Oil Seal is a perfectly smooth shaft in the region of the seal, particularly if shaft surface speed is high and the medium to be sealed is under a certain amount of excess pressure. The surface roughness of the shaft depends on the average profile depth Ra of the tool marks caused by the machining process. Oil Seals made of PTFE require, independent of the surface speed, a surface roughness of between 0,1 to 0,2 mm, because PTFE has less wear resistance than rubber seals. For normal circumstances, the shaft in the region of the seal must have a surface roughness of approximately: To summarize, the surface of the shaft in the region of the seal should not have noticeable machining marks. For pivoting shafts and other difficult or critical sealing applications, it is recommended that Oil Seals with a helical groove hydrodynamic pattern, which has a pumping effect, be used. When grinding and polishing, an axial movement of the grindstone along the shaft must be avoided in order to prevent machine lay.

In addition to preventing oil leaks, oil seals also help reduce noise and vibration in machinery, improving the overall working environment. By providing a tight seal around rotating shafts and moving parts, seals help reduce friction and improve the efficiency of the equipment.One of the main principles of power transmission is consistent lubrication. Shaft seals play a hugely important role in this. Imagine a situation involving a shaft-mount reducer – electric motor prime mover, driven by belts, motion controlled by a torque arm – with an improperly seated seal. A blown-out input shaft seal is a nightmare situation, necessitating an entire breakdown and reassembly, not to mention re-aligning and re-tensioning the belts.
