Its sealing edge comes in full contact with the shaft surface in order to provide excellent sealing performance.

The perfect solution to this is to always use an oil seal that fits properly; the right size of the seal should be used. And in other cases, backup devices should be used to avoid the buildup of clearance gaps within the mating edges.
In these instances, Viton can be the perfect sealing material for methanol/ethanol-blended gasoline.
Several prominent companies specialize in the manufacturing of oil seals, offering a wide range of sealing solutions for industrial and automotive applications. These companies leverage advanced manufacturing capabilities, extensive research and development, and a deep understanding of industry-specific requirements to produce high-quality oil seals. Leading companies in the oil seal manufacturing sector are known for their commitment to innovation, quality, and customer satisfaction, providing reliable sealing solutions for critical components in machinery and vehicles.
Most oil seals are designed to support very low-pressure (8 psi or less) applications. If at all, there will be additional pressure along the way, pressure relief should be put into play. This is why it’s important to know the characteristics of the oil seals you are considering and compare them with your application.
