WHAT IS THE DIFFERENCE BETWEEN MECHANICAL SEAL AND OIL SEAL?
- In conclusion, oil seals play a crucial role in preventing the leakage of fluids in machinery and equipment. The 25, 35, and 70 oil seals are popular choices due to their versatility, durability, and effectiveness. By choosing the right size and type of oil seal and ensuring proper installation and maintenance, you can prolong the life of your equipment and ensure its optimal performance.
- The primary function of a rubber valve cover gasket is to prevent oil from seeping out of the engine. Engine oil, vital for lubrication and cooling, would otherwise escape through any gaps, leading to oil loss, potential engine damage, and reduced efficiency. Moreover, the gasket also keeps contaminants like dust and water from entering the engine, safeguarding its internal components.
A piston oil seal, also known as a piston seal ring, is a critical component in an internal combustion engine. It plays a crucial role in preventing oil leakage from the piston and ensuring efficient engine operation.
Investing in quality seals will benefit you and your machine in the long run. The cost of replacing oil seals will be higher as cheaper alternatives are constantly being purchased. Not to mention, the efficiency and quality of low-cost oil seals may not be reliable.

If this is not possible, you may be able to fit the lower retaining bolt into the upper mounting support, to hold the engine level. Or the gearbox may have to be jacked up and supported.

On most cars you need not remove the engine to get at the sump . But often you have to raise it slightly and wedge it on its mountings so that the sump moves clear of the front- suspension cross member.

OIL SEALS
The simplest way is to know either the preferred manufacturers part number, the overall sizes of shaft diameter, housing diameter and bore depth.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.
