Lip Seal
Lip seals hold the oil inside a rotating shaft while keeping air, dust, and dirt out. Lip seals are versatile, high-performance seals used for uniform, low-pressure applications. Lip seals are a type of oil seal used to retain oil lubricants inside a hydraulic system. They are primarily used for rotary applications.
Lip seals can have one, two, three, or more lips. Multiple lip designs provide extra protection against contaminants. Most lip seals were originally made of rubber materials, but Teflon is largely replacing traditional rubber materials because it can withstand high pressure applications in which rubber seals would fail. Teflon® is a plastic material that provides enhanced lubrication properties, resistance to wear, and added strength.
