When included, the garter spring applies pressure to the sealing lip against the shaft, ensuring a tight seal. The choice of material, like that of the case, largely depends on the environment of use.
PTFE, or Polytetrafluoroethylene, is a highly versatile synthetic polymer renowned for its exceptional chemical resistance, low friction coefficient, and high-temperature stability. It finds extensive application in various industries, particularly in the manufacturing of oil seals. An oil seal, fundamentally, is a mechanical device designed to prevent the leakage of oil while allowing the rotation or linear movement of shafts and axles. The integration of PTFE into oil seals brings about a myriad of advantages.Vulcanizates of several fluoroelastomers, listed in Table 14.1, were exposed to a standard 5W-30 engine oil, ASTM Service Fluid 105, for up to 6 weeks at 150°C (302°F).5 The oil was changed weekly, but was not aerated. Retained elongation was measured after exposure for 1, 2, 3, and 6 weeks; data are shown in Fig. 14.3. The results indicate that bisphenol-cured FKM-A500 VDF/HFP copolymer, FKM-B600 VDF/HFP/TFE terpolymer, and peroxide-cured FEPM-7456 TFE/P/VDF terpolymer lost most of their original elongation over the course of the test exposure, indicating considerable additional cross-linking occurred by reaction with amine- and phenol-containing oil additives. The other fluoroelastomers showed better retention of elongation, being much less susceptible to additional crosslinking. Note that FEPM-7456 contains a high level of VDF (about 30%), while FEPM-7506 contains a relatively low VDF level (10–15%) to serve as cure site for bisphenol curing. The other FEPM types contain no VDF.

Rubber oil seals are widely used in various applications due to their versatility, durability, and resistance to oil and other fluids. These seals are designed to provide effective sealing solutions for rotating or reciprocating shafts, preventing the escape of lubricants and the entry of contaminants. Rubber oil seals play a crucial role in maintaining the efficiency and longevity of industrial machinery, automotive engines, and other equipment by ensuring proper lubrication and protection of internal components.
