PTFE Dual Lip Spring Loaded Shaft Seal

A PTFE Dual Lip Spring Loaded Shaft Seal is a type of seal designed to prevent fluid or gas escape from a spinning shaft. Two sealing lips constructed of polytetrafluoroethylene (PTFE), a high-performance fluoropolymer material recognised for its outstanding chemical resistance, minimal friction, and great thermal stability, are used in this type of seal. The spring-activated design exerts a steady force on the sealing lips, ensuring a strong seal against the shaft even at low pressures. This makes the seal excellent for high-speed applications where fluid or gas leakage is a concern.

Product Name: PTFE Dual Lip Spring Loaded Shaft Seal

The double lip design of the seal provides an extra layer of protection against leakage, making it more effective than single lip seals. The seal is able to accommodate some misalignment and deflection of the shaft, making it more versatile and adaptable to different applications.

The PTFE material used in this type of seal is resistant to a wide range of chemicals and is suitable for use in both high and low temperatures. The spring energized design ensures that the seal is self-lubricating, reducing wear and extending the service life of the seal.

Overall, the PTFE Spring Energized Double Lip Shaft Seal is a reliable and effective sealing solution for demanding applications in a range of industries, including aerospace, automotive, and chemical processing.
