PTFE Oil Seals - A relatively new and exciting oil seal, the use of polytetrafluoroethylene means that they can withstand dry or unlubricated operations. With a massive thermal range of -130ºC to +200ºC and a strong resistance to chemicals, they are considered to be the future of rotary shaft seals.
When selecting oil seals for automotive and industrial use, it's essential to consider factors such as compatibility, durability, and performance specifications. The seals should be designed to withstand the specific operating conditions and environmental factors they will encounter. Additionally, choosing reputable suppliers and manufacturers known for producing high-quality oil seals is crucial to ensure the reliability and longevity of the components.
Its sealing edge comes in full contact with the shaft surface in order to provide excellent sealing performance.
(See Figure 3.)
The sealing process involves the interaction between the rotating shaft and the elastomeric material, resulting in a dynamic barrier that prevents fluid leakage and maintains system integrity.

First, an elastomer, most often nitrile, is vulcanised to a metal ring. This creates a stiffening effect that includes a specialised metal tension spring directly behind the sealing lip, keeping the oil seal firmly in place against the moving part.
