In addition to the installation procedure, our specialists and suppliers would also like to draw your attention to some cases that occur around oil seals.
The best seal performance is achieved when close shaft and bore tolerances are present. Other factors include shaft eccentricity, end play and vibration.


In conclusion, oil seals play a critical role in high-pressure systems by preventing leaks and maintaining the integrity of the machinery. With proper design, materials, and maintenance, high-pressure oil seals can withstand the extreme pressures and harsh conditions commonly found in industrial settings. By investing in quality seals and regular maintenance, operators can ensure the reliability and efficiency of their high-pressure systems for years to come.
Materials for Oil Seals
Friction modifiers: Friction modifiers help reduce friction when your engine is operating under high temperatures and with heavy loads. This additive can also help you maximize your fuel efficiency.
Well-balanced in terms of resistance to abrasion and high and low temperatures
In engine applications, square rubber gaskets are used to seal various components such as valve covers, oil pans, and intake manifolds. These gaskets help prevent oil and fuel leaks, ensuring the engine operates smoothly and efficiently.
