Classical oil seals consist of a metal housing that carries the dynamic sealing lip and provides the static sealing function. These are usually manufactured of elastomer material, such as ACM, Silicone or FPM. Further, since they are in contact with the surface of the rotating shaft, the lip is pressed onto the shaft surface by means of a spring ring.
Various materials with unique properties are utilised in the construction of rotary shaft seals, allowing manufacturers to tailor the sealing solution to specific industry requirements and ensure optimal performance.

However, the new variant also comes with less good properties. Namely less flexibility and less resistance during assembly. Most damages therefore occur during the installation of PTFE oil seals.

ptfe oil seal. This makes them suitable for use in applications where other types of seals may be damaged by exposure to chemicals.
Many – too numerous to list, covering a vast range of designs, sizes, and materials suitable for a never-ending range of applications. Some designs conform to International Standards such as BS1399 and DIN 3760 for metric sizes and seal types, but the majority have been manufactured to suit particular applications – hence the enormous selection available. This blog is intended to assist in this selection and will consider seal type, materials, and sizes.
