Viton double lip rotary shaft seals are a type of rotary shaft seal designed with two sealing lips made from Viton, a brand of fluoroelastomer rubber known for its exceptional chemical resistance and high-temperature tolerance. The double lip design provides an extra layer of protection, enhancing the sealing efficiency and preventing the ingress of contaminants and the escape of fluids in demanding and chemically aggressive environments.

Here are some key features and characteristics of Viton double lip rotary shaft seals:

1. Viton Material: Viton is a fluoroelastomer with outstanding resistance to a wide range of chemicals, including oils, fuels, solvents, acids, and bases. It is also highly resistant to high temperatures, making it suitable for applications with elevated heat.
2. Double Lip Design: These seals have two sealing lips, as the name suggests. The double lip design provides an additional barrier to improve sealing effectiveness, ensuring better protection against fluid leakage and contamination.
3. Dynamic Sealing: Viton double lip rotary shaft seals are designed for dynamic applications where the shaft is in continuous rotation. They maintain their seal even when the shaft is in motion.
4. Chemical Resistance: Viton’s resistance to aggressive chemicals and solvents makes these seals ideal for applications where other rubber materials might not perform effectively.
5. High-Temperature Tolerance: Viton can withstand high temperatures, which makes these seals suitable for applications where elevated heat is a concern.
6. Versatile Applications: Viton double lip seals are used in various industries, including chemical processing, pharmaceuticals, automotive, and other applications where chemical resistance and high-temperature sealing are required.
7. Customizable: Viton double lip seals can be customized to meet specific application requirements, including variations in size and design features.
8. Lubrication: Proper lubrication is important for the longevity and performance of Viton double lip rotary shaft seals. Lubrication helps reduce friction, heat generation, and wear on the sealing lips.

These seals are commonly found in equipment such as pumps, mixers, and agitators in chemical processing plants, as well as in various applications where resistance to aggressive chemicals and high temperatures is essential. Viton double lip rotary shaft seals are a preferred choice when it comes to ensuring the integrity of the sealing system in challenging environments.
